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.

Hi I have just bought a second-hand lenovo W530 (with i7-3840QM quadcore processor), and it was delivered with a 135W power adapter. The seller tells me that the 135W one was the original power adapter for that computer. I would like to know if you know this is true, or all the computer were originally delivered with the 170W power adapter. As I would use the computer for engineering simulations I would like to be sure that the the computer have not CPU throttling due to the 135W power adapter when using near 100% CPU and GPU. Kind regards

Hi all, As my W510 was already experiencing thermal issues prior to this, so I stepped in to replace the thermal paste with the thermal Grizzly Kryonaut on the Graphics Adapter and the CPU. I applied a thin layer although it was slightly uneven, then replaced the components. When I tried re-booting, the computer got stuck at the bios screen and I powered it off. It now refuses to power up, and I hear a rather loud chirping sound coming from the attached 135W adapter, as if the adapter is powering on and off repeatedly. I have reseated the RAM and reset the CMOS but to no avail. Have I created a short circuit somewhere? Is my unit really dead? I would appreciate any assistance here. Thanks!

I Just got my W530 3720QM K2000m and i find it ridiculous that it cant use the 90W Adapter when idle and uses the battery. I Read threads of similar things with the W520, as well as some on the W510, and it appears that this used to work on the W510, 90W power adapter delivered the system in working condition with reduced performance. Now, i use my laptop as both a worstation and an entertainment laptop. if i were to go on a flight or be in a car, i sure wont be doing intensive VMware or 3d stuff, so 90W would be more than sufficient to drive the laptop as well as charge the laptop. i even have a Killawatt meter, i plugged in the 170W Adapter into it, and then ran my laptop while having the battery charged. the max power consumption that it pulled was 70W At the wall, surfing the web in optimus mode. Why cant we have a power saver mode to allow usage of the 90W adapter? or at least have the Choice between "battery only" - reduced performance anyways and "reduced performance AC/only"? At the very least it would avoid draining the battery for absolutely no good reason. My system idles at under 30watts anyways and that would leave 60W to do anything else, for example charging the battery at 40W - to give the total of 70W at the wall, from the 170W Brick. i Wish to see a revised bios to correct this or at least allow this. i dont believe its impossible or too complex to code. it was done on the W510, i dont see why it cant be done on newer, improved, smarter, more ...

A:W530 Power Adapters, 90W vs 135W Vs 170W

This topic has been discussed in this thread:  and this thread.  I have not seen a satisfactory reason why the notebook cannot operate from 90W in a reduced performance mode.  The conditions that cause a 135W power draw are rare. For light use my W520 draws 15-20 watts. As a thought experiment, consider what would happen if you had a 90W adapter attached, and suddenly the notebook tried to draw 135W.  The adapter would shut down due to over-current. This is exactly the same scenario that would occur if I unplugged the adapter while operating. The notebook is designed to instantly switch over to battery if the AC power goes away. So there is no risk to the computer. Maybe if the adapter is poorly designed, it could be damaged. I challenge Lenovo to provide a technical reason why the W520 and W530 cannot operate off a 90W supply in a reduced performance mode.  I believe a good portion of the 135W is for charging the battery. So if the power drain exceeds 90W, stop charging the battery. 90W should be more than enough to operate the notebook only under any circumstance. Under most circumstances, it can operate the computer and charge the battery.  This thread describes mods that will trick the notebook into thinking it has a different capacity power supply.

The tips I got with this Kensington 33197 power adapter have numbers stenciled on them like N3, N5, N19, etc. The tips sold on their web site make no mention of the "N" numbers and have numbers like K20059, K20050, etc. and there is no cross reference.

You can also see a complete reference for "N" numbers to all the laptops they support at the above link. Again, no mention of the numbers Kensington uses on their site.

I need a cross reference for these kinds of numbers.

Kensington referred me to their telephone tech support; but, there is a language or cultural barrier that prevents their understanding what I need.

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.

Hopefully someone here can help solve my issue, because I'm practically at my wit's end with it. I recently ran Lenovo's Updater program and it installed a few new things on my Laptop... I don't remember all of them, but I know one was a BIOS update, a Firmware update (can't remember specifically for what though), as well as a few programs I was missing on my computer (like Lenovo Power Management, just to name one).  It's something I hadn't ran for a good year, so I'm sure everything was using an older version! In any case, it seems after I did that, many of the games on my computer started playing worse.  Long story short, after checking out a few programs to monitor what my computer's doing (CPU-Z, and even Intel's Extreme Tuning Utility), I noticed that my Laptop's suddenly only using a portion of what it can do. For example, the core speed should be able to go up to 2.6ghz - 3.3ghz... but strangely, it's staying at a solid 1.20ghz the whole time. No matter if I run any graphic-intensive games or do anything else that might need some extra power, it stays exactly at that number. Here's the weird thing though.  If I unplug my Laptop and let it run off the battery?  It shoots straight up to the 2.6ghz-3.3ghz, as it's supposed to.  As soon as I plug it in again, it drops right back down to 1.20ghz and many of my games run like crap again. I've tried looking up solutions online, but I've found nothing that helps.

This review in regards to the next Generation T series from Lenovo.  
 
The machine I tested is based on a Intel i7-8565U 8th Generation Whiskey Lake 1.8GHz quad-core CPU.  It came with 16 GB of DDR4 memory and a bright 14? QHD(2560 x 1440) with Dolby Vision 500 nit IPS screen.  The screen I got according to HWiNFO64 is Model LEN40AE with a Monitor name of B14QAN02.0. It looks to my naked eye as the same as my X1 Yoga 3 screen with Dolby Vision.  It?s a very nice screen. This screen does not support touch.  The side bezels have shrunk(see pictures below).
 
As for graphics.  It came with a Intel UHD Graphics 620 and Nvidia GeForce MX250 with 2GB GDDR5 memory.
 
For connectivity it came with 2 USB 3.1 Gen1 ports, 1 USB Type-C, 1 HDMI 1.4, 1 Thunderbolt 3, a MicroSD Card reader and 1 Audio Jack.  An interesting feature on this laptop that I personally have not seen before is the left side USB C port can charge other USB C devices.  It can output 5V at 1.5A. I personally have not been able to try this.

This is a common problem (I see lots of posts)
The problem source is the [Dell] AC adapter.  PA-21 Family, 65W, P/N: NX061.  It is made in China.
I have an XPS M1330.  Using Dell after warranty service, replaced the Mother Board twice, replaced the battery twice, replaced the AC adapter twice - not fixing it.
Turns out the power warning message is very informative.  It states "Please connect a Dell 65W AC adapter or greater for best system performance".  So, I plugged in my Dell 95W adapter - WOW Problem Solved.
A lab test of my new Dell 65W AC adapter shows it to be 64.6 watts.  If this unit gets hot (like after several hours of use), it may not put out the full 65 watts - the system may not recognize the adapter, it may power the system ok, but won't charge the battery.
These units burn out after only a few months of use. Their cables are too fragile. If Dell's or their supplier's Quality Control can't produce a reliable 65W product - I found seveal "Made In USA" universal adapters.

I just got a T590 and started using it last week. I have two pairs of speakers, one (Harman Kardon) a little nicer than the other (Alans). When I first started using the laptop, I could play music using the Harman Kardon speakers just fine. A couple days in, I played music from the Alans speakers. After that, I tried to play music again from the HKs, but it won't work. It's almost like the laptop thinks the HK speakers are a microphone. When I connected them, a little microphone icon appeared on the screen. Under the sound settings in the control panel, it showed both external speakers and an external microphone, and when I tried to play music, it would show that the volume of the external microphone was very high, and the volume of the external speakers on but very low. The sound coming though the speakers was soft, garbled, and mixed with a lot of noise. I got the same results with a pair of headphones. The Alans speakers still work. In the Device Manager, my sound controller is "Realtek High Definition Audio(SST)". I have tried both disabling and re-enabling it, and uninstalling it and letting the computer reinstall, and downloading the driver from Lenovo and manually reinstalling. This did not fix the problem.

Anyway could somebody measure the resistance between ground and signal pin ? I have read somewhere here that making short circuit between ground and signal pin making power causing charger recognizable for laptop as 135W . could anybody confirm that before I damage laptop ? thanks

Hi, I am considering to buy the 4K version of one of these laptops. I have used the X1E but I am bothered by the fan noise even under BIOS 1.19. Do these laptops have noisy fan issues? Are they fully compatible with Linux right out of the box? I mean do all functions work right after installation of Linux without further work from the user? How is the battery life? Thanks.

I connect  a Thunderbolt 3 Dock Gen 2 to my L390 Yoga with firmware 1.18 and the latest dock-drivers 10011. Then I try to make a firmware update of the dockingstation with firmware-version 3.1.61. After unpacking I start the "ThinkPad Thunderbolt 3 Dock Gen2_Workstation Dock firmware update.exe" with admin-rights. Then I get a the following warning: "Can't read Thunderbol controller version, Will skip Thunderbolt firmware update!". After clicking "OK" the updater continue until the next message appear: "Your dock has new firmware can be upgraded, please click [Update] to start firmware upgrade."  and the Current Version shows: = <unknown>.If I click the update-button the programm continue until the message: "Firmware update completed!" appear. A click on the OK-button close the update-program.If a start the firmware-update program again the same error happens. The update-program can't retrieve the current version of the docking station. So is the update-program buggy? The installed OS is Windows 10-1903 with latest patches and the docking with the 2nd usb-c connector from above on th left side. I bought the Thunderbolt 3 Dock Gen 2 because the Lenovo tool "docking-search" told me, that there are 3 dockings compatible with ThinkPad L390 Yoga. So what to do?

For the last two weeks, every time I start my Dell INSPIRON E1705 while using the power supply I am greeted with the following message. "The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 90W AC adapter or higher for best system operation". I press the F1 Key and everything works fine. I've read about this on other websites and most say it's a design flaw in the power supply after the cord has been properly wound around the supply as designed. Apparently a few of the cords internal wire strands become broken and cause this message. My computer is from June 2006 and shouldn't be having this issue so early...or ever. This seems like a flaw that should have created some type of manufacturers recall since so many people are having this issue. I'm of course out of warranty, will Dell replace this free of charge?

A:Power Supply - "The AC power adapter type cannot be determined....."

You are correct, the failure is due toloss of the power supply ID signal. Sometimes this happens because of strain on the plug, which breaks the signal wire. Some even are so severe that the insulation breaks away from the plug; this is due to rough handling. The other cause is one or more of the power socket solder connections to the system board become broken. This also is related to severe handling. I have seen one case where all three power connections and three of four mechanical connections were disconnected. If the power supply is bad, a replacement will cure the problem. If not, then the socket is bad, and this will require a system board replacement. If you are experienced, you can try to resolder the connections. I am experienced and was not able to get my daughter's E6000 to work by resoldered. More recent Dells are using a replacable power connection board which is a much cheaper repair.

My needs can be satisfied with T590/P53s and they have num keypad. P1/X1 Extreme on the other hand have powerful CPU (45W, 6 cores) and powerful GPU (good for 3D rendering, GIS explorations). Gaming is not a big consideration. Rational for GPU is really from a GIS perspective (in case there is some 3D modeling). T590/P53s - adequate, does not get hot, relatively quiet. Soldered RAM -- if a problem then that is not easily rectified. Is this ever an issue? I mean, RAM going bad (I have had this once only in business laptops). If soldered RAM goes bad, can the add-on still work? Or have to replace MoBo. P1/X1 Extreme -- more future proof, Carbon bodies, two DIMM slots. Powerful GPU - great for gaming and 4K displays. No soldered RAM issue. But seems that we are still discovering issues with cooling, fan noise, and battery life is limiting (hard to get advertised battery life without much tweaking).  Price diff b/w two, on sale, is about $250. Very tempting to go with P1/Xtreme but battery life/cooling issues are becoming a drag.  Appreciate any guidance.

I bought a Dynex USB 2.0 4-Port Hub last week and have decided to add an external power supply to power the hub. The short and terse User Manual notes on the final page that a 5Volt / 2.5 Amp Power Adapter may be connected. I called their customer support number and talked to a lady, but her best advice was return to the store and ask there. My experience with this store over the years has been fat chance for this kind of request. Has anyone got a suggestion as to where I can purchase such a USB Power Adapter?
 

A:USB Hub Power Adapter

Radio Shack would be a good place to start although you might have to get one of their adjustable models. A Google search should also turn up something. Actually I just replaced my D-Link powered USB1 hub with a USB2 model. The old one is just sitting around and it has a 5V 2.4A adapter. If you want it so you can use the adapter just PM me and I'll send it to you.
