T480 waking up when LID is opened

Q: T480 waking up when LID is opened

Hi, I would like my PC NOT to wake up when I open my lid and at the same time going to sleep when I close it? I had this feature on my previous HP laptop running Win7. Now I'm running Win 10 and wonder if that;s rather a matter of operating system or the PC itself? Regards,Marcin

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.)

Lenovo ThinkPad T480, Product Number 20L5CTO1WW, BIOS N24ET48W 1.23, Windows 10 64 bit. All updates distributed by Lenovo and Windows are applied. No unique, custom settings to power, sleep, battery, etc. The laptop will wake from sleep about 75% of the time. The rest of the time, the Windows 10 log in screen appears but neither the keyboard nor mouse respond. I always have to hard restart in those instances. There is also no consistency regarding the occurrences, such as whether it occurs when the computer is on battery before sleep and then power after sleep, or battery before and after sleep, or power before sleep and battery after sleep, and power before sleep and power after sleep. Under all such instances, I have seen this issue occur where waking from sleep stalls and requires a hard restart. Thanks for the guidance on how to address the issue.

I have a P50 running Windows 10 Enterprise Fall Creators Update (1709) OS Build 16299.248 I've been surprised on a couple of occasions to open my backpack and find the P50 is running and VERY HOT.  Even tho, when I put it in the backpack it was sleeping.  Since the P50 doesn't have a physical latch to keep the lid closed, it is sometimes able to open a few millimeters (just enough to wake it out of sleep). I've configured the power management settings (under Control Panel->Power Options->Choose what closing the lid does) to "Do nothing" when I close the lid.And this indeed works most of the time.  Most of the time, opening the lid does nothing, and I have to press the power button or Fn key to wake the P50.However, I've discovered that if the P50 ever goes into hibernation (either explicitly, or after being in sleep for a long time) then this issue with coming out of sleep by opening the lid happens.  In order to make the P50 return to the expected behavior (in other words NOT waking when the lid is opened) I must do a complete shutdown/reboot. Does anyone else notice their P50 comes out of sleep when opening the lid (even tho you've set "When I close the lid" = "Do Nothing"?

I have my laptop set to hibernate when closing the lid and starting yesterday (had this for about a month), upon waking up, I get stuck on the windows boot manager. Even if I exit out from it, it comes back to this screen. The only workaround is to force a reboot. I'm recent with both lenovo and windows update and ran lenovo diagnostics but everything comes out ok. Reset the BIOS settings to default as well. But to no avail. Setting the boot priority to my SSD first does nothing as well.

Hi
My son has an ipad and an iphone. the iphone is not sycned to the ipad but a single email has been opened on the ipad that he has only accessed via his iphone. How can this happen?
 

A:one email looks opened when i ahve not opened it?

It sounds like you are using IMAP, which syncs the emails with the server, not the devices. So when one device shows up and is read there, the other will then show the same thing (being read). This is normal.

I've noticed my fan always stays on regading the temps when my machine is plugged on the 65W charger, temperatures remain between 38 and 57 on light use, but even when idling the fan kicks on as soon as I plug in my charger and turns off a couple seconds after I plug it off. I have tried to fix it by installing the patch mentioned on https://pcsupport.lenovo.com/es/en/solutions/ht506625 and changin the BIOS profile for the plugged status (it's on the same profile now both for AC plugged and unplugged) but the problem perists. Anyone knows how to fix this issue without the need to install 3rd party software or can point me to the windows 10 settings that regukate this behaviour? Thanks in advance.

T480 doesn?t charge with the USB-C AC charger plugged in. when the AC charger is plugged in, the orange LED illuminates and blinks three times, the plugged in logo pops up momentarily then nothing. The thinkpad was purchased in October this year with everything working flawlessly... I then left the standard 45W charger at an airport. I ordered a replacement and received it 6 weeks ago and has been working fine until today... Do I have a dead AC charger? anyone have similar issues?

Hello all, Just received my sixth thinkpad in the last 23 years. It arrived yesterday.  It is a: T480, I7-8550U, 16GB(8+8), 512 M.2 SSD, iGPU, Win10 Pro The fan is really annoying.  It goes on and off constantly.  It seems to ramp up to full speed.  I have been reading about fan noise with this model all over the internet.  Is there a way for it to run constantly at a lower speed than the constant on and off?  My previous model was a T430 never had issues with fan noise (it was very quiet too when it ran). Currently running a test:  Not using the laptop at all.  Opened 1 tab on Chrome and have it sitting on cnn.com.  Also, opened one tab on Edge also on cnn.com.  Task manager open.  Chrome uses less CPU but more memory than Edge.  CPU is running between 15% and 20%.  Fan turns on every minute or so for about 20 to 30 seconds then goes off. It is loud and annoying going on and off.  Why can't it just be a constant lower speed?  On and off is ridiculous.  If this keeps up this machine is going back. Thanks for any replies and suggestions.

Hi,Recently bought a T480 with the 150MX Nvidia card. The laptop works great during normal operation during work etc but when I get home and want to play some games, nothing is working as it should. What happens is this:When I start the game everything is running good but after a few minutes I can see my CPU start to lower it's power limit (PL1) slowly towards 5W. It will stop at 5W never gaining any wattage back until i restart computer. The PL1 is at 15W when computer is newly booted. I have tried to uninstall the Intel Dynamic Platform and Thermal Framework, this results in that the processor is fixed at 15W but after a while the iGPU will go crazy and goes to 100% leaving the CPU at 2W = 0.2Ghz. And I have to restart. So this is not a valid solution. All my power settings are on maximum performance ofc.I have tried almost everything I can think of and been browsing all kind of reddit threads without any long term solution.

Hey! I was wondering any kind of SSDs would work with the T480? Right now I bought it with 500 GB HDD and Intel Optane (16Gb), but in the future, I might consider upgrading to 512 nVME SSD for system. Also, what do you guys know about the battery life upon general internet usage? I bought a battery with 72Wh so in total it would be 96 Wh. Plus, I also own a Varta Power Bank (13mAh) 48,1 Wh. Do you guys believe it could charge the battery by any chance? https://www.varta-consumer.com/en/products/portable-power/overview/details/lcd-power-bank-13000 Please let me know you guys think!

I ordered a T480 with the Geforce MX150 option. Was surprised to see my delivered unit with Intel UHD 620 and simultaneously active with the Geforce GPU. The Intel GPU however is the default display adapter. Intel UHD 620 is active display adapterI've never quite seen this before. Desktop mainboard BIOS would typically disable the onboard GPU if slotted with an actual video card (leaving the OS blind to its presence), and all my previous laptops that I configured with a discrete GPU would have just that alone. Am I supposed to disable the UHD 620 in Device Manager in order to force the Geforce to take over? I don't see anything in the BIOS that can influence this (in fact it seems to suggest the UHD is in charge with its shared memory setting).

Hi everyone, today I upgraded the RAM and the SSD of my T480. I am absolutely not doing this for the first time and I was really careful. I removed the external battery and deactivated the internal battery before starting with the procedure. I used only ESD-safe tools and an ESD-wristband to make sure that the device doens't get damaged by static discharge.After installing the components, my device would no longer turn on. When I connect the charger, the power led flashes 3x but when I press the powervbutton nothing happens. No fan spin, no lights turning on, absolutly nothing.I then tried removing the RAM and the SSD and turning on the machine. But that didn't work as well.After that I tried removing all the power sources (internal and external battery, CMOS-battery), pressing the power button for 60 seconds and leaving the device for 1 hour before reconnecting everything. But it still can't turn it on. Do you guys have any idea what I could try to make my device work again? Thanks in advance. --resonance

After perusing this and other forums looking for a definitive answer, there seem to be dissenting opinions on whether using the drive caddy and adapter cable in the HDD bay will allow 2280 M.2 NVMe SSD drives to utilize all 4 PCIe lanes. I want to know if there is a reason to shop for a higher end M.2 drive if I can't extract full performance out of it.

I don't have one to test, but the platform spec for the T480 says that some of the T480 machines have SATA drives and some have this: "M.2 SSD / PCIe NVMe, PCIe 3.0 x 4"
 
To me, that means is should use 4 lanes

Hi Folks, Here at the company i work at we recently got lots of X280s and T480s which are fully usb-c for charging and docking station.  We use the thinkpad hybrid docking station and what we've seen is that when we plug in the dock the monitors will take 1-3 minutes to fully startup. The ethernet and charging works as soon as plugged in but thats it unless we wait 1-3 minutes as mentioned for the monitors. I've tried different docking stations and the problem persists. Another issue is the fact that sometimes the LED light next to the USB-C port stays lit orange even when not plugged in. I've done the latest bios and thunderbolt firmware updates.  The two drivers that fail when plugged in are the UCSI USB Connector manager and an Unknown USB Device Port reset. ive already uninstalled them but they keep coming back like that.  Premier support said to change settings in the BIOS which we did together but the problem persists, they said the next step is to switch out the motherboard but this has happened to 30+ machines so we cannot keep having this issue as it affects our users productivity.  Hoping to hear that someone here has an resolution and that we are not the only ones experiencing this major hardware/software failure related to the X280s and T480s
