Intel Wifi with modern power management = Slow speeds after wake from sleep... A workaround fix...

Q: Intel Wifi with modern power management = Slow speeds after wake from sleep... A workaround fix...

Hello, After looking in this forums i've found at least 4 long threads with people experiencing the same issue with various different wifi chips and access point hardware. It appears intel has some huge fault in their modern wifi chipset that triggers a bug which is easily reproduced to many of us by putting the computer into sleep for a short period of time then resuming.Symptoms of the bug?Incredible slow actual wifi speeds even though the wifi indicator tells you that you have great connectivity, for instance a 802.11AC session with 866mbit/s connectivity actually comes out at 30mbit/s in actual tests when the bug is triggered.What causes the bug?The cause of the bug is when the computer goes into low power mode or "sleep", which is something modern laptops do even though you've set it not to do, modern power saving keeps parts of the computer awake while others are sleeping such as the wifi chip actually responds to smb requests and ping yet you cannot remote into the computer becauset the gpu and gfx rendering module is sleeping.How to fix it?There's no fix. Neither Intel or Lenovo wants to take responsibility, each side is blaming the other, Lenovo will tell you its either your Access Point or your ISP, while Intel will say it's Lenovo's responsibility or an issue with your AP/ISP. Either way since they does not appear to be able to reproduce the issue in their test labs (no actual confirmation that they have even tried though) we're stuck with this issue which appears to be affecting a large spectrum of machines.Then what?There's no official fix for the problem, i've tried everything, like disabling modern power management, disabling mimo and various other settings for the wifi card, nothing appears to help. The only thing that solves it is when you trigger a reset of the wifi adapter, lets say you change a setting or simply disable and enable the wifi adapter when affected by the bug your wifi speeds will go from 30mbit/s to 350mbit/s+ in actual speeds on a 802.11AC connection instantly (the later speeds may vary due to your setup etc but increase in speeds are massive.) Video showcasing the issue: The workaround solution (because we're being ignored by Intel and Lenovo technicans!)The only workaround i've gotten to work in this scenario after days of testing is to make a script that resets the network adapter everytime the computer resumes from sleep. It's not a nice way of doing things but it's a fix that i've been using and it works good because modern chips are fast and you won't even notice that it isn't connected for a few seconds when resuming from sleep.Do the following:Create a bat file with following:netsh interface set interface "WiFi" Disablenetsh interface set interface "WiFi" Enable Note that "Wifi" is the name of your wifi adapter.Create a new task in task scheduler:Set it to trigger "on an event"Basic > Log > SystemEvent ID 507 Set task to run at highest privileges.Now when you resume from sleep it will run automatically and fix the issue, you most likely won't notice it as you're most likely bypassing your login screen for the first seconds when it runs in the background.Hopefully we can get some attention to this issue, if not then at least you may get proper performance on your device rather being stuck in year 2005 with 30mbit/s wifi.

Preferred Solution: Intel Wifi with modern power management = Slow speeds after wake from sleep... A workaround fix...

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


Hello, I've had my X1C7 carbon for a few weeks now and i've discovered a bug that is causing me some distress. I've been troubleshooting for some time now why my wifi appears slow even though when checking the wifi status it tells me i have 866mbits full speed connectivity. Upon restarting the machine and running a speedtest i get real world speeds of 450mbit/s which is perfeclty normal in 802.11 AC envoirment, you actually never get 866mbits as advertised due to various overhead and disturbance but 450mbit/s is acceptable. Once i close the lid to sleep the machine, wait for lets say 5 minutes, i resume from sleep and try the same speedtest, i get 30mbit/s. The wifi still indicates i am at 866mbit/s but real world speeds are greatly reduced. It won't change until i reset the adapter by either changing a setting that triggers it to reconnect to the network or simply just manually reconnect. So what i've tried is the following: * Uninstalling the driver and attempted to install the driver from intels website (cannot be installed, it just fails without any notice, no message in event viewer either, driver can be found here: https://downloadcenter.intel.com/product/99446/Intel-Wireless-AC-9560)* Re-installing the driver found on lenovo website.* Disabling Mimo Power Save Mode* Setting both NIC and AP to 802.11N instead of 802.11AC, tried both VHT 40 and VHT 80 on the channels.* Tried "prefer 5ghz network" setting etc. I've verified from the AP's dire...

I've been investigating an issue that my laptop has when going into sleep mode while connected to certain public networks and access points. After coming out of sleep when connected to these networks, all my network adapters will remain in an "off" state (media disconnected status in ipconfig /all), that takes forever to force it out of (I still don't have a clear remedy, it just seems to finally turn back on after multiple power cycles and airplane mode toggles).As best as I can tell, it's likely a PSP issue with the ac8625 wifi card as described here: https://www.intel.com/content/www/us/en/support/articles/000005645/network-and-i-o/wireless-networki...However, for some reason my X1 Carbon 6th Gen laptop doesn't have ANY of the common window10 power management options available... I don't have a power management tab in the adapter's properties page: I dont' have any wireless adapter power control options in the advanced power settings control panel: And I can't access any of the advanced settings in the Intel ProSet tool. Is this something Lenovo purposefully disabled?? I've never seen a computer set up to exclude all the important advanced power management features. I've gone into the messy lenovo advantage to turn off the weird airplane power saving feature, but I can't find any other way to re-enable power controls so I can adjust the PSP power settings for this adapter.

Just got a new X1 Extreme (Gen2, 20QV, i7-9850H) and it has been working perfectly for a couple of days. Yesterday a notification appeared that i should upgrade the Intel Management Engine Interface. After that upgrade the Wifi is extremely (!) slow and its almost useless. Especially the "upload" maxes out around 1Mbit/s. Can i downgrade the ME drivers somehow? This is the current details:Intel Management Engine Interface 1914.12.0.1256ME firmware 1.25 (2019-08-19) Thanks for any advice on how to solve this.

My PC is fairly new and I'm having problems with slow shutdowns/restarts and slow sleep/wakes. Recently it seems to fail waking altogether and restarts after a while instead. Usually during waking I just have a black screen for a long time before the reset/restart but sometimes I see the Windows log-in screen but it's unresponsive.
The problem predates my CPU undervolting and doesn't seem to change when I switch RAM settings back to Auto instead of XMP (I my RAM necessitates some kind of overclock in order to function at its rated speed).

Can anyone advise how to proceed? Thanks.

I am new here. Hoping someone can help me out with this issue. I work in IT so am not a complete computer bonehead and am at my wits end with this.

My laptop is about 4 years old, it's a toshiba. For whatever reason, it started taking 5+ minutes to wake up from sleeping. If it sleeps for an hour, it's OK.. but if you leave it sleep all night and try to wake it up in the morning, it's quite cranky. After the 5+ minute wake up, it performs as normal. It was running Windows 7 Home 32 bit.

Troubleshooting steps that I have taken are as follows.

Reinstalled windows. Issue was resolved! but after about 2-3 weeks, issue came back. I thought maybe it was some type of windows update, so I reinstalled windows again and paid closer attention to the updates. Issue presented itself again after 2-3 weeks, and there were no updates immediately done prior to it starting.

I started to think maybe it was something related to my hard drive, so i performed laptop surgery and swapped out my original hard drive with a solid slate drive, and installed windows 7 Ultimate 64 bit (this laptop can support 64 bit so I figured why not upgrade.).

issue again was resolved for a few weeks, and now it's back to taking 5+ minutes to wake up again.

If you're turning the laptop on from scratch, it takes 10-15 seconds tops. if you're restarting, it's 10-15 seconds tops (man, I love SSD...)... if you're waking itup within the hour, its 1-2 seconds. But anything longer then that, 5+ minutes.

My new HP laptop 15-ac114nx [Intel Core i3 @ 2.00GHz, 4GB RAM, 1TB HDD] running Windows 10 64 bit has a serious wifi problem. Ever since I have bought the laptop Wifi internet speeds seem to be comparitively very slow on battery than when plugged in. I have a 20 Mbps connection which provides a reasonable browsing and download speed on all my other devices. The issue with this laptop is that when running on battery and connected using wifi even opening a webpage such as facebook or youtube takes an awfully lot of time lets say like 5 to 10 seconds and sometimes much more, whereas if I do the same with the power cord plugged in, the web pages appear as soon as I click their links(i.e. Vey Fast/Instantaneously).  To add further clarity to the situation I tested the download speed of a particular file while running on battery and with the cord plugged in. I started the download of a file [Java Development Kit ~ 160MB] using chrome with the cord plugged in and navigated to the chrome downloads page to monitor the download progress. The download speed was about 1000-1200 Kbps. Midway through the download I removed the power cord. Immediately the speeds dropped down to 20-30Kbps and sometimes even much lower.  After approximately 10 seconds I plugged the cord back in and wow the download speed went back up to approx a 1000 Kbps. After sometime I removed the cord again and as a result the speed dropped down again. Plugged the cord again and it rose back up. NOw this c... Read more

Welcome to the Community.
It might help to know the make and model of the USB-C device that's at the center of the issue. It sounds as if 1909 has installed the wrong driver, changed the power savings mode of the driver or altered a registry key.  Wouldn't be the first time a Windows update has done  something like that.

I experienced a feature on my friends laptop called Modern Standby.  It adds the ability to go into and resume from something called "Modern Standby".  The sleep state in older PCs was S3 but in this new model it is S0i3, which Microsoft refers to as Modern Standby and Intel calls S0 Low Power Idle - I found technical details thru research but I could not determine which new PCs have this feature. So, with this Modern Standby feature enabled, I can wake her Laptop from Sleep by saying "Hey Cortana".  This even works with her laptop lid down.I think this is a great feature but I was surprised I did not know about it, when I was doing research to purchase a new laptop this summer. How can a consumer buying from retail know which Lenovo Laptops support this capability ? Thanks,Paul Review

Hi there,

We've got 3 Dell precision towers 5810 that work great, except for a possible bios bug, which I can reproduce on all machines:

I'm using the installed NIC: Intel ethernet server adapter i210-t1.
Our computers go powerless every night (mains power) after a normal pc shutdown. Every morning, when the power is back on, I want to wake up all computers in our building with Wake On Lan (WOL) by sending a 'magic packet' over the network.
This normally works well if the machine has been switched on and off with the power button / windows shutdown. But when I unplug the machine (mains power), wait and plug in the mains power again, the computer does not respond to the WOL packet. (Maybe the PCI-E NIC does not get power on plugging in the mains of machine for the first time).
It works well on the integrated (motherboard) NIC. BIOS / power / sleep state settings seem to be ok.

The machine will work fine, but after sleep and you open the lid, the monitor won't wake. You can however install the older driver asus has on their website which will restore functionality.
Is this a bios problem or what exactly is not compatible with the newer intel drivers?

I live in a place where we have power shortages from time to time. I have my Dell desktop pc attached to a UPS and i have configured the pc to go to sleep after 5 minutes when on UPS. Is there anyway to wake up the pc automatically once the power is on? I have connected my UPS with USB cable to the pc, and the pc treats the UPS as a battery. I use this pc as a media centre so this feature is something i really need.
I am on Windows 7 Ultimate.


A:Wake the PC from sleep/hibernation when power comes up

With it being a Dell the option may very well be hidden (with no way to unhide it), but have a look in the bios under the Power options for anything relating to "restore on power loss". If it is there it is likely set to disabled (the default on most if not all motherboards), set it to enabled and that should do it.

This started two days ago. When waking up from sleep, the power cycles on and off about every 2-3 seconds. This is happening before any programs are restarted, and the screen is still dark. I first thought it was my new battery backup. I called APC, and they agreed that it had failed even thou the UPS was only 10 days old,. So I disconnected it, and plugged the computer into a dedicated outlet, removed the UPS monitoring software with Revo, and then cleaned the registry with CClean, with no effect. The only new programs I've loaded, were about 2 weeks ago I added itunes, and a Win update or 2, and the battery backup software, which has been removed.
Thanks in advance for your help.

Just set up this new laptop and I never achieve more than about 1-2Mbps upload or download speeds. Its running the latest driver from Lenovo so I tried to update the adapter using the most current driver from Intel directly which made no difference. Did all Windows updates including 1903 feature update but nothing changed. Speeds of all other wifi devices in my house are fine so its not my dual band Linksys router that the cause. Any ideas what else it could be before I resort to returning the laptop.And just to clarify, it happens on both the 2.4 and the 5 Ghz band and also whether I use the built in Intel adapter or my TPLink wifi USB dongle.Ran another test. The built in Intel adapter and my TPLink wifi dongle work just fine when booting the laptop to a Windows 10 PE USB (Gandalfs Redstone 2 to be exact). Clearly something is going on with preloaded copy of Windows 10. The PE version on the USB is a much older version, probably created using a version of Win10 from at least a year or two ago. The OEM version on the laptop has all the current update and is version 1903. There has gotta be something in Windows thats causing it but can't imagine what.

Dear all
I'm trying to get wake on lan working on my new computer after a shutdown from windows. I'm using the following hardware/software:
Asrock X99 Extreme 4 with onboard Intel I218-V --> connected trough wired lan
Windows 10 EDU 64 bit
The wake on lan works when I put the system in hibernation or sleep. However on shutdown it doesn't work. On shutdown the lights on the ethernet connector of the motherboard are off. If I boot the system to the BIOS and shut down from there the lights are still on and the wake on lan works. So it seems like windows 10 is disabling the network card on shutdown.
I tried changing the following settings:
- in BIOS: turned on wake-on-Lan. and turned off Deep Sleep
- in windows in the divice manager at the power management tab of the I218-V I made sure to select: "wake on magic packet", "wake on pattern match", "wake on magic Packet from power off State".
- Disabled "fast start-up" from windows 10 as I found some people had problems with that combination.
Does anyone have any suggestions on how to make sure windows 10 does not disable the network card on shutdown so that wake on lan still works?

- open Event Viewer (run eventvwr.msc from the "Run" dialog))
- expand the Custom Views category (left click on the > next to the words "Custom Views")
- right click on Administrative Events
- select "Save all Events in Custom View as..."

I was working away the other day and I received a Lenovo critical pop up which I recall was for the Intel update and I clicked the update button.
I have a Lenovo W520 and now whenever I put the computer to sleep, it looks like it went to sleep however the sleep light only goes on for a second and then goes off, where the light should stay lit until I want to use the computer again.  Now the computer will only start back up if I press the power button and it asks if I want to start the computer normally etc. as it looks like the system now crashes on sleep.
I checked the power options and all looks ok and I don't see new messages in the event viewer except for "The previous system shutdown at 9:37:45 PM on ?06/?07/?2017 was unexpected." and "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."
Any suggestions would be appreciated.

Yes, indeed the famous sleep problem that everyone seems to still have.

I have searched high and low for other users with the same problem as I do and did not get anywhere. I have a HP Pavillion M7750N for those who care to know with only one addition to it being a M-Audio Delta 44 sound card for Sound recording purposes.

My problem is that when the computer goes on sleep mode (S3) it hangs untill it finaly reboots and brings up an error in windows. In other words I can never have the computer in sleep mode or hibernation for that matter.

Since I did not find any information to help in this process I started to look deeper to the problem and I found a temporary solution. I followed Step 8 in the terrific instruction bellow:

Power Options and Sleep Mode Problems

Doing so I caught that HD Audio Control Panel (RtHDVCpl.exe) was preventing my PC to go into sleep mode.

Now I can go in sleep mode but I lost the ability to control my sound input/output that I kinda liked with Realtek. I tried to uninstall Realtek HD Audio Manager and install the latest version but with no better results.

Reason for this post is one for anyone to use in case disabling Realtek HD Audio Control Panel can do the trick to fix your problem. And second, to request help or comments to fix mine.

Sorry about the lenght of my storry. Great Forum by the way!

I've been getting persistent BSOD's when attempting to wake up my computer (Lenovo Twist u230) from sleep. I am also sporadically getting Kernal Data Inpage Error BSOD while using my computer.

My machine is Windows 8, installed from factory with a recent refresh done. SFC /SCANNOW and DISM both come up clean. All of my hardware diagnostics are also clean.

Which hardware diagnostics have you done?

Please run Driver Verifier according to these instructions: Driver Verifier Settings

Just a guess at this point, but try removing Diskeeper to see if that helps.
If not that, then try removing the Citrix software to see if it helps.

We've had some power offs and ons due to snow storms recently. But, I don't know if the power is the actual problem.

Typically when I come to the computer its in the sleep mode and a mouse movement or keyboard key would wake up the machine. In the last few days neither do a thing.

A couple observations-

1) My Samsung monitor's power blue light , stays blue and blinks
2) The case power on button light is on and steady lite.
3) Pressing the reset doesn't go to reset, kind of does nothing
4) Pressing and holding the power button acts the same as the reset

In the end , I turn the power strip off then on again and then all's well.

The board is an Asus, with an AMD processor, 16 gig mem.

Samsung SSD
Any ideas?

When laptop is in sleep mode, light behind power button slowly dims and brightens repeatedly. Wiggle or click mouse or press keys on keyboard does nothing. Flick power button wakes it. Device Mgr says mouse and keyboard can wake system.
Win7 would wake with wiggle mouse. Any way to get 8.1 to do that?

Hi there, I've been dealing with a "female" L580.... Power management is behaving quite randomly. Sometimes it just turns itself off (with or without charger), or cannot wake it up from sleep, ..... When it fails to start the power button led remains ON but no fan no screen no other leds no nothing. I've tried emptying all condensers by disconnecting internal battery and pushing power button for a few seconds and all that.... Sometimes it's also possible for the machine to stay on for days doing memory, disk, virus and other all sorts of tests trying to figure it out - nothing comes out of it, all clean. Tried replacing internal battery for another new OEM one, and the symptons remain. Just cannot find a pattern or a correlation. There are no errors, temperatures, nothing that can lead to a conclusion on which component may be damaged, if anything is damaged. I have to say I'm little bit disappointed as I've bought Lenovo Prof line to come away from this sort of thing. It's a less than 1 year old high spec machine..... Doesn't make much sense to me. Any thoughts or experience on this kind of behaviour? Thanks. Regards, Bruno Belo.

Hi all,
I'm using Win10 x64 and Intel 520 240GB SSD:

For my mobo, Asus P8Z77-V-Deluxe, I downloaded the official asus chipset drivers.
There is one for Win8.1 x64 and a Beta version for Win10.
The chipset driver for Win8.1 has installed the following:
1. under Device Manager> IDE ATA/ATAPI controller > Inter 7 series/C216 chipset Family SATA AHCI Controller
2. Version - Date 2013/08/01
If I install the Asus Win10 chipset driver, then instead of the Inel SATA controller, I'll end up having Standard SATA controller by Microsoft.
I'm currently using the Asus beta Win10 chipset driver, however I manually installed the Intel SATA controller which is officially supported on Win8.1 and is digitally signed.
I ran two SSD benchmark test with AS SSD (latest version).
With just the official Win8.1 chipset driver as mentioned above, I'm getting the following results:

With the Win10 beta chipset driver and the Standard SATA controller by Microsoft:

And here are the test results made by Intel SSD 520 Series Solid State Drive | Intel,SSD,520 Series,Solid State Drive,SSDSC2CW240A3,Benchmarks,Performance,Reviews,Olin Coles,Intel SSD 520 Series Solid State Drive SSDSC2CW240A3 Benchmark Performance Review by Olin Coles

Can you spot the difference???
I'm wondering if someone here can please guide me and see if it's possible to improve the results.

My wife and I both have the x1 Extreme 20mf. Last week I ran the update called "Intel Management Engine 12.0 Firmware for Windows 10 64-bit - ThinkPad P1, X1 Extreme" because it was labeled critical. Since then both computers are having a problem. Maybe 50% of the time when booting up, the computer fails to recognize the wifi module. In device manager there is a yellow triangle next to the Intel 9560 wifi card. A simple uninstall/reinstall or disable/reenable fixes the problem and wifi works fine, but on next boot up maybe it won't. Again it happens about 50% of the time. It's possible this started happening after the upgrade to bios 1.18 as well, not sure. I did those both around the same time.  Additionally the computer just seems unstable on start up. The keyboard backlighting turns on and off like 3 times before the screen registers. Maybe that's normal or... I don't know. We're both running Windows 10, 64bit, professional build 1809 and bios 1.18. Is anyone else experiencing this?Is there anyway to roll back that firmware update?Is there any other solution? Thanks in advance for any help.

I was comparing my new P52 (Xeon processor, 32 GB, NVMe SSD) to the wake speed of my friend's 5 year old MacBook Air.  The MacBook Air resumes from sleep in less than 1 second. It prompts you for your password very quickly.  Windows 10 x64 (1809 17763.134) takes minimally 5-8 seconds (never less) when lifting the lid to get the background image and finally prompt for the password. When the resume process starts, there is a fair amount of disk activity.  I also noticed that the P52 takes at least 5 seconds to achieve sleep mode. From the time I close the lid to the time the red led on the ThinkPad cover starts blinking. The "Fast startup" option in power settings is DISABLED. What do other see on their systems ?  Is this a Windows definiciency  or a ThinkPad specific issue ?

Hi all.

I have built a new computer system for my parents and am having some annoying power management problems.

The system specs are:
Asus M4A7TD USB3
Athlon II x4 640
4GB RAM DDR31600
Ati Radeon 4350 1Gb

All drivers and BIOS are up to date.

The annoyances stem from the fact that when the system is powered down from Windows, the machine keeps power through the LAN Port and USB bus, keeping lights on the mouse, keyboard and card reader which is a problem for my parents. I realise that this is normal, and - I believe - so the computer can be woken up?

However, BIOS option for 'wake on LAN/KB/Mouse/USB' etc is all disabled.

There is a setting for energy savings requirement EuP, which when enabled, over rides all other settings, and when this EuP setting is selected and the computer is turned off, all power is switched off, and no lights are left on.

However, if EuP is active, and I set the computer to sleep in Windows 7, there is no way to wake the machine up from sleep other than killing power to the PSU. The power button flashes on and off but does nothing when you press it. Nothing happens with keyboard or mouse action.

However, with EuP disabled, sleep works as it should from Windows.

Is there something I'm missing?

Many thanks.

Greetings everyone!I've got a Lenovo T520 running Windows 7 Pro 64-bit with Service Pack 1. Two days ago I upgraded Intel Management Engine Firmware to version via Lenovo System Update. Since then my laptop has lost the ability to sleep. When I press the Sleep key my laptop performs an emergency power-off and then asks me if I want to start Windows normally or in the safe mode when I power it up again.The hybrid sleep function still works, but it takes much longer than just dumping the current session into RAM. I tried everything: updated the BIOS firmware (1.46) and the Intel 3000 video card drivers ( I have the latest Lenovo Power Manager software (6.68.13) too.Is there a way to roll back the Intel Management Engine Firmware to an earlier version?

This is just a small thing, but my X1 Extreme feels like it takes awfully long to wake from sleep. Opening the lid of my laptop, I expect it to be ready to go immediately, especially with a supposedly excellent SSD. But the screen stays black for a second or two, then the power button flashes, a few more seconds go by, the screen finally turns on, a few more seconds and Windows Hello decides to activate, the mouse finally starts to respond, and then I'm finally in. Just feels awfully janky for a performance device. Anyone experience this or have any fixes?

Hello Folks! First off, I'm an experienced IT Admin, and I've owned 6 Thinkpads over the years... the machine in question today being a Thinkpad W530 (K1000M, 16 GB RAM, 240GB Intel SSD, Windows 7 x64, Latest Drivers and BIOS). I've been having a weird issue where out of no where, and while on battery, the computer will go to its default "uh oh, battery is running out, save everything!" mode. Aka, if hibernate is enabled, the computer will hibernate. If I force disable hibernate in Windows, then the computer will sleep. So the problem is the same, and for others the symptoms may present as "hibernate without warning" instead of "sleep without warning". Either way, this happens sporadically, and often at inconvenient moments. The first few times, I didn't know what was up, but I've looked into it a bit further now. Right after this sporadic forced "sleep"/"hibernate" happens, I checked the event log: "The system is entering sleep.Sleep Reason: Battery" Now obviously that's no good. I was kinda mystified the first time I saw that, as neither the power manager, nor the built-in Windows gauge were showing low battery. And after I resume from sleep/hibernate, the battery level is still fine. Today though, I think I found a major clue. This time, instead of just jumping to a sleep/hibernate event, I got a Windows Critical Low Battery pop-up warning first, and looking at the Windows battery gauge it showed 7% left, even though the Lenovo Power Mana...

I have the same problem with my Lenovo T510 and my new P70.   I setted the sleep mode and hibernate mode to "never" in the Power Management and even use : Performance setting and my P70 always go the sleep mode after 4-5 minutes if the computer is idle. I was able to avoid the problem with my T510 by pausing a video.  That avoid the computer to do in sleep mode (yes the workaround is stupid.. but it works). But that stupid workaround doesn't work with the P70.  If I let my computer without touching it, it will go in sleep mode.  Don't download anything while going to the bathroom. PS.  I have Windows 10 on both my computers. I asked the same question on Microsoft Windows 10 forums and got an answer that reset all the setting to the default value, but that didn't fix the issue.  And now that I have the same problems with two lenovo laptop, I'm not sure that the problem is only with Windows and more with Lenovo drivers.

Hello All,

In the last two weeks I have been experiencing something very strange with my Windows 10 Pro. When my laptop resumes from sleep the Wireless is turned off in Windows. I don't believe it was an update because I have defer updates enabled. Unfortunately, I just noticed System Restore was turned off.

1) I have checked the power settings in Device Manager and the device is NOT checked to use power management)
2) I have updated to the latest wireless driver available.

Any ideas would be greatly appreciated.
Edit: I believe this issue has something specifically to do with Sleep because when I reboot or shutdown/power-on the Wireless is enabled and working fine. It only seems to be when Windows goes into sleep mode.

A:Wireless turned off after lid closed or sleep (Not Power Management)

It is common behavior for any devices to be powered down if you close the lid to place into sleep mode.

I have a "LENOVO 80E3 Lenovo G50-45" (according to Belarc Utilities report) and I'm running Windows 8.1 Pro.When the Lenovo hibernates and blanks the screen, in order to waken it, I have to press the power button. (It then goes to my login page, which is exactly where I want it to go.)I'd rather have it exit hibernation mode / blank screen mode when I move the mouse or swipe my finger across the touch pad.How do I enable that?

A:How to enable mouse move to wake Lenovo G50-45 from sleep instead of power button?

Hi Tomlenovo,
Welcome to the Forums.
When the system goes to the hibernate the screen will be black in order to resume power button is the only way to resume. Through touchpad this option cannot be set, if the system is locked and if the screen is black then if you swife the finger on the touchpad the screen will resume with login screen.
 Hope this helps. Do post back if the issue persists!

I have a HP Pavilion p6837c and I'm using an Edimax dongle to catch a WiFi signal since I'm unable to hard wire the desktop computer with Ethernet. According to Speed Test.net, I'm getting 2.75 Mbps download and 9.35 Mbps upload. Absolutely awful.

When I took my desktop to another room where I could use Ethernet, I'm getting speeds of 94 Mbps download.

I have another HP computer that has a WiFi card built in and I'm getting speeds with that one of 20 Mbps download.

Is there any advice on what I can do to increase the speed of the P6837c using, perhaps, a different WiFi desktop adapter?

The other option for me is pay my ISP to install another modem and then pay an extra $5/month. I'm open to doing that, but would prefer to buy a good desktop adapter that will get decent speeds.


A:Extremely Slow Speeds Through WiFi

What's the exact description of that Edimax wireless adapter?
If you have a webpage for it, please post the link to it.

Does your modem/router(unknown description) and Edimax wireless adapter support 2.4 GHz and 5 GHz wireless bands?

A wired ethernet connection tends to produce higher and more stable download speeds than what a wireless connection does.
Depending on how far away that room is from your modem/router, you might consider buying and using a 50' - 100' long ethernet cable.

I live in a townhouse in a college campus which means we all have the same ISP. I checked the channels and checked wifi stumbler. They both look good. For the last few days I have been getting really slow internet speeds after 7 pm till 1 am. I am paying for 25 mbps but around that time I get 0.5 mbps. I have the latest firmware for the router. I talked to customer support twice and all they did was reset my router and tell me to power cycle it. It can't be range of the router because my laptop is right next to it.

Can someone please help me fix this problem.
