Thinkpad T42 keyboard problem

Q: Thinkpad T42 keyboard problem

my laptop keyboard is not working right. first the specs. ibm thinkpad T42, machine type 2378, model R4U, OS xp-pro coa sp2, 512mb ram. my cpu usage jumps up and down between 40 to 100% when running my spy sweeper, fire fox isp and a voice chat program. when i am not running any programs except whats need for the laptop to work the cpu usage is 3 to 10%. and i have available ram. OK now with the problem. when i try to type on the keyboard the letters or numbers don't show up. but if i hold the keys down it will show up there is a delay of about 2 seconds. if i just push down the keys at normal speed it wont show up. it will only show up if i hold it down for about 2 seconds. i thought the keyboard was bad so i bought a new one from the factory. i installed it but it is still doing the same thing. just to let you know every thing else about the computer works great and and all my programs do not have any lag. its only the problem with keyboard delay. i will just add this i have cleaned up the computer,defragged, ran spy ware and anti virus and it has been working fine for years without any problems.

Help please!

I brought home the laptop I use at work. I am trying to login to my employer's VPN network. For some reason the keyboard keys that share letters and numbers (for example, o is also 6, K is also 5 etc) will only type numbers. I cannot get letters when I type those keys, so I cannot login with my password,
What am I doing wrong? I don't think I changed any configurations so why can I not get letters from these keys?

Hi all, I have a Thinkpad x240 that I bought refurbrished in ferbruary. It was working perfectly untill recently I've noticed a problem with a bult-in keyboard. So microphone mute key stopped working and when I press down and hold left Alt key, microphone mute indicator powers on. Also sometimes Fn lock led stays powered on even though Fn lock is disabled. I've noticed this behavior after I've used logitech wireless mouse with usb unified reciever. Is there a way to fix this strange behavior? I've already cleaned contacts on the keyboard connector on the motherboard and cable, but it didn't fix the problem. Also it seems like it is not OS dependet, because it has the same behavior in bios/linux/windows 7 & 10.

Hi all, Since a few days I have been suffering from a keyboard problem.Sometimes the keyboard doesn't register my strokes, despite the fact that I'm pushing normally. In fact when it happens the amount of pressure doesn't seem to matter. Sometimes it is a letter and sometimes it happens with the Enter button. In any case it goes away after I keep pressing for 5/6 times. I was hoping that anyone here could provide me with a suggestion as to how to fix this problem. Kind regards, Niels

I was just given a Thinkpad 390. It was having problems booting past the bio screen. Eventually, after trying to enter bios and no luck, I tried hooking up the keyboard from my tower. The keyboard worked in the thinkpad, but I found that the only way the laptop will boot up is if the keyboard is plugged in. Then, once in windows (2000) the laptop keyboard still wont work, whether the tower keyboard is plugged in or not. I have no idea if anything was spilled on the machine or not. Does anyone know how to get into the keyboard to make sure its plugged into the board correctly?? I unscrewed the screws, but its not as easy as that though. Any ideas? Thanks

Ok here's the story... I borrowed a semi broken thinkpad from a friend... monitor is cracked and most of the keys don't work... so when I got it I used a external keyboard.. no problem... with a splitter for the mouse... no problem... It has windows 2000 pro. I personally use windows 98 so I was trying to get my scroll mouse to work so I loaded the software for that mouse... big mistake..... after that No mouse or keyboard worked.... I eventually tried another mouse that goes through the parallel port... ah that works... still no keyboard... I unistalled the mouse and keyboard many times... with no luck... my next thought was the com port so I uninstalled that.... nope still no keyboard.. even the few keys from the laptop that did work before do not..nor the laptops own mouse. So I hope I said it all... except because this is borrowed I don't have the discs.... so what else? Joel

I have a Lenovo Thinkpad
Model : E431 (Edge Series) Number: 62774UQ
(3rd Gen Ci5/ 4GB/ 500GB 7200rpm HDD/ Windows 10)

I purchase this in 2013. It has been used moderately over the first 2/ 2 1/2 years
The laptop was idle for the past 6 months.
After I recharged the laptop, I noticed that some keys began to malfunction. So I installed Windows 10 (Windows 7 previously). However the problem persisted.
The shift key seems to be pressed as per its own wish and the sticky keys notifications comes up on its own. The Enter key sometimes works, sometimes it doesn't, sometimes on its own. The backspace key also does not function sometimes.
I then opened up the laptop and removed the keyboard from the laptop and then replugged it back in hoping it would make a difference, but it didn't.
The touchpad also become unresponsive sometimes and I have to press the Windows key twice to make it work again.
What could be the source of the problem? Is it the keyboard or is it the motherboard to blame? Kindly provide a solution.

I bought my P50 in March of 2016. I've been very happy with my purchase overall, the only disappointment has been the low key-rollover property of the built-in keyboard. I am a programmer/game developer, and it is important for me to have a keyboard that supports multiple simultaneous keystrokes. After taking ownership, I found that the keyboard drops strokes with as few as 2 keys already held down, which makes it pretty useless for gaming.  I work around this by plugging in a USB keyboard when I need to test my game projects. At the time I purchased, there was only one option for the keyboard. Today, I was browsing the Lenovo online store, and noticed that there's now an option for a backlit keyboard in addition to the standard non-backlit keyboard.  Under "Help Me Decide" it says: Lenovo has refreshed the keyset on all ThinkPad laptops, outfitting them with the ThinkPad Precision Keyboard.This new keyset allows a more comfortable, fluid and accurate typing experience with it's slate of individually rounded, spacious, and low-set keys. The ThinkPad Precision Keyboard simultaneously delivers a modern look and feel to your ThinkPad.*Select models are available with a backlit keyset as standard, or as an optional upgrade.*Most 15.6" models come standard with full keyboard including dedicated number pad. I am wondering if this refreshed keyboard means a  higher rollover.

I'm using an on screen keyboard to type. Ihad a weird .exe file running in processes after using google and I couldn't end it. My computer was slow and it seemed like another google re-direct virus. I tried running virus scanners, but they would shut down or wouldn't open. I ran combofix, but lost internet connection while doing so. My screen was frozen when my connection came back. I had to shut down. I tried to run it a couple more times but it froze. After a few reboots to safe and regular modes and trying to run virus scanners, I noticed my keyboard doesn't respond. I managed to reinstall malwarebytes and get ridof viruses but my keyboard still doesn't work.

You are infected. Can you boot into Safe Mode (press F8 at bootup)? Does the keyboard work here? If not have you tried an external keyboard? Run Combofix from Safe Mode, you do not need to be online when it runs. Be sure to disable your Anti-Virus before it scans. If still having problems, click on the link for Virus/Trojan in my signature and post there for more help.

The "period" key was sticking on my laptop last night then a little later, it worked fine, but then my right shift key was giving me trouble.
I suspect that somehow a piece of food worked its way into the keyboard(though it is hard to imagine, no more clearance than there is). Probably from one of the kids. Whatever is down there seems to be moving around.

I attempted to disassemble, and got as far as the actual touchpad. There is a IC cable leading from the touchpad down to the motherboard that is keeping me from opening the lid up all the way. I would rather get the advice of someone who is familiar with these before I "experiment and attempt it on my own.

Can anyone tell me how to take the IC cable from the touchpad?

Thanks in advance.

I have a Thinkpad Yoga 12 model. It is using Windows 10. What is the driver/software I should check to make sure I'm running the latest version for the equivalent of what used to be called "Transitions"?  Basically something that recognizes various keyboard configurations such as tablet mode, tent mode, etc. and appropriately disables or re-enables the keyboard? Two things happened last night as I was playing a game in tent mode:- firstly I could not get the screen to rotate 180 degrees when I switched from tablet mode to normal laptop mode by rotating the keyboard and flipping to normal orientation.  So everything was displayed upside-down.- the keyboard was unresponsive, but I could use the touch screen fine and use the Windows button under the screen to get to the Start menu.   So basically somehow something stopped responsing that should have told the system that I flipped the laptop from tent mode to normal mode and also rotated the keyboard forward.

Greetings,I recevently received a Thinkpad 13 intended for small office use.  However, when I inspected the hardware, I discovered a problem at the bottom left corner of the keyboard (pictures below).??As you can see, the corner of the keyboard base is bulging upward.  It very clearly should not be this way, as the other corner is flush with the edge of the chassis (picture below). ??So, I tried to wiggle the corner down into place, but it did no good.  I don't want to have to send it back (I just got it, and need to use it), but I certainly don't want damage or poor quality control to be ignored.Does anyone know if I can fix this myself?  If not, what is the best way to inform Lenovo of this problem?Cheers,

Hey everyone, Recently bought this laptop. Loving everything about it. However, I did a fresh install of Windows 10 (it wasn't an upgrade from Win8.1, but rather a new install of Win10 after I replaced the harddrive to a 1TB SSD). Since then I've reinstalled everything I could get from the site. Every Lenovo driver set and utility. Updated the BIOS. Consulted the Solution Center. Ran scans from the utilities and the site. I've literally tried EVERYTHING that's obvious, and I can't get the backlight to come on at all. When I first received the laptop with the old harddrive, the backlight worked just fine. Since I put in the new SSD with a fresh install, I cannot for the life of me get it to turn on. Pressing Fn+SPACE gets it to show the little icon on screen that it's SUPPOSED to be turned on, but it isn't on. So I'm at a loss here. I sincerely doubt it's a hardware issue, because literally the only thing that's changed is the harddrive. If there's a specific driver for the keyboard backlight, I'd love to know about it. Thanks in advance!

Do you want to try out something just to check that the keyboard light is working?
I have a TP Yoga 14 here and when I access the BIOS the keyboard lights up when I press "FN+Space", give it a try if it works for you.
 
I do not know if it requires an special driver, but I'm using the Windows 10 that was updated over the Win8.1 that came included.
 
The other things that cames to my mind is trying to boot other OS from the USB and see if the keyboard lights up.

Ever since I had to format and reinstall WinXP my laptop, it has developed several annoying issues. First that developed was the built in touchpad and trackpoint stopped working intermittantly. Even with updating the driver, they seldom work. I found that opening the properties page in device manager makes it work for about 10 seconds, then it cuts out. Even then, it only allows the touchpad to function for the time, leaving the trackpoint useless. That doesn't matter to me, since I can use the USB mouse when I'm in the house. It just would be nice to rely on the touchpad when I need it!

Then a couple months later, the keyboard cuts out. Not completely, mind you... It works during POST, it works when it asks you to choose OS (I dual booted for 2k and XP), and most of the time it works for me to input my password into the user select screen of WinXP. The cutting out of the KB is completely random, though I've noticed that it's more frequent to cut out when loading IE or Firefox too soon after booting up, though it is not limited to the loading of those programs. Some times, it will get past POST and OS selection, but not work to enter the password.

The IBM troubleshooting page has been useless. All they want to say is that the KB is shot, but that's only because the only options is "The keyboard does not work at all!", which is not the case. I am typing this on the laptop in question as we speak, so obviously it works.
