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

Basically, it seems most ThinkPads (confirmed on my X1 Carbon, P1, T470, and T460) have a serious problem with their keyboards not detecting keypresses. For example: typing "load" quickly produces "loda" every time. "Oad" is fine, but "load" will reliably produce "loda". This error seems to be related to the extremely slow polling rate of ThinkPad keyboards. Using an external keyboard will not cause the same issue. Additional info: https://www.reddit.com/r/thinkpad/comments/9ivh0u/thinkpad_keyboards_measurement_of_polling_lag_and/additional info 2: https://www.reddit.com/r/thinkpad/comments/9j70v6/thinkpad_keyboard_firmware_worse_than_anyone/This is a serious problem that hinders productivity of anyone who types quickly, and it needs to be addressed.Thank you.

Hi there,  I have been using an X1 carbon 7 gen  Laptop for over 6 months, and I absolutely love the tactile feel, sound and the crispness of the keys! On ocassion, I have the HDMI of my laptop plugged into a larger 38" monitor, wich it powers well.  I am loooking for a desktop/ full size keyboard, that would emulate the feel and satisfaction I get from using the keyboard of my X1 Carbon 7th Gen. I have gone through several, including the Lenovo 500 Series. Nothing compares or even comes close. Does anyone have any suggestions? It could be a 3rd party manufacturer or even Lenovo....doesn't matter...I thoroughly enjoy typing on my laptop, and would like to have the same experience when doing it on the fuller size keyboard. Any advice, suggestions or insight will be greatly appreciated? Thank you kinldy in advance!Shahmn

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

Hi. My T23 Thinkpad had a key pop off thanks to a book falling on the keyboard. I have the key and both unbroken little plastic holder parts.

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 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 really hate the ISO keyboard. They managed to take the existing keyboard design, which is already sub-optimal, based on 1800 typewriters, and managed to make it worse! With an ISO keyboard your pinkies have to travel twice as far from home row just to hit two of the most used keys, shift and return:At least some companies recognize this problem and have been giving the option to buy laptops with ANSI US keyboards, all over the world. Sadly, I couldn't find a single EU Lenovo online shop that carried this keyboard option, and the US shop will not sell internationally. I would love to buy a P40 Yoga, but the ISO keyboard is a deal breaker, because I spend most of my computer time typing. Do you have any advice?

Hello! I have a ThinkPad X220, the original keyboard broke a few weeks ago. I have replaced it with a keyboard I found on ebay, but this one just doesn't type the same as the original. It makes a lot of sound during typing and the keys give absolutely zero feedback. Besides that, it just did not fit great, I needed to bend the four tabs holding the keyboard under the palmrest down a bit, because they were too high to fit in the desired slots. I am looking for a genuine Lenovo keyboard. If possible, I would stay away from ebay this time, because the one I ordered does not look like the one advertised, and is not genuine. I do not want to buy another keyboard that just types terrible. Some of keyboards advertised as 'genuine Lenovo' just look exactly the same as the non-original I have now.So if someone knows a trusted ebay seller that sells the original, please let me know. If I can get it from Lenovo, that would be just perfect. However, I cannot buy part 45N2241 at the Lenovo Replacement Parts website anymore. The original keyboard has the following FRU No.: 45N2241. Thanks in advance! SubieForest2001

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 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.
