Only About Half of Keyboard Keys Actually Work

Helping a neighbor.
This is a Compaq Presario CQ-61, just out of warranty. Only about half of the keyboard keys, when pressed, display. Is there a fairly easy and reliable way to determine whether the keyboard itself has gone bad, or if it's a motherboard or other hardware issue? I don't want to recommend the purchase of a replacement keyboard, assuming HP even sells them, only to have it installed without solving the problem.
Will appreciate any help and advice.

I'm sorry about the lack of detail
I'm getting Medium Errors most of the time, but sometimes the burner outright rejects the blank CD.
I have used a wide range of brands, but nothing seems to work. I've tried Nexxtech (obviously a bad choice), Maxell, Memorex, Verbatim, and Sony CDRs, and they all seem to fail at about the same rate (Nexxtechs were noticeably worse, though)

Hi lialou,
I got your message about the new keyboard failing. I would recommend doing a full System Recovery to see if that restores the function back to those keys. Make sure that you back up your data beforehand.

If that doesn't work it could be an issue with the connecting cables and you should give us a call regarding repair options. You can reach HP Total Care at 1-800-474-6836 in North America or start here if you live outside of North America.

My backlit keyboard keys not working?

How come my backlit keyboard keys not working? When I try to use them I get a circle with a line running through it?

Jax, the backlight is currently usinig a sensor to turn the light on and off for you. This uses the least amount of battery. If you want to test or control the lighting yourself, go to the Apple Menu, select System Preferences, click on the Keyboard icon. Here you can turn the automatic setting on and off. If it is off, you can use they keyboard keys to turn the keyboard lighting on and off.
Exactly!

My MacBook Air running on Snow Leopard gets extremely slow (almost like a hang, except if you wait about half an hr, it actually moves) after login interface. Sometimes it never gets past the background of the homepage, desktop doesn't seem to load. After multiple forced shut downs and left to run for hours, sometimes the desktop loads but the dock does not respond when applications are opened. The computer is then unable to shut down normally. Forced shut downs are necessary most times. Time machine backup takes extremely long, and attempts to use the time machine to bring the laptop back to the time befiore the problem arose was met with extremely slow and hung time machine function.
Please help!

There isn't much besides a failing hard drive or other hardware fault that can cause those symptoms. Run the Apple Hardware Test, or just take it to an Apple Store for testing.

Usb keyboard keys stop working after 10 minutes on mac mini osx lion

I am using a mid-2010 mac mini with opitical drive, updated to OS X Lion. Within the last two days I noticed a certain section of my wired keyboard eventually stops working. These are the right arrow key, as well as the 1, 2, 3, zero, period and enter keys. The virtual on-screen keyboard works just fine. I've come home from work and powered the mac and all keys work fine for ten minutes so it can't be that the keys are worn. I was going to take it to Apple Store genius bar but now I can't tell if it's the hardware or the lion software that's buggy.

I had terrible problems last year with the USB ports on my 20" display. They were made worse when I installed a USB 2.0 PCI card in my G5.
At the time the advice I got was that I should avoid using the display as a USB hub. Apparently the ports are only intended for devices relating to the display (whatever that means). Ridiculous if you ask me. I succesfully use my Cubase SX dongle in the back of the display but that's all.

Pavilion 15-b142dx Some Keyboard keys not working

A friend gave me their Pavilion 15-b142dx sleekbook, apparently AFTER they spilled some type of liquid in it. I was able to revive the computer, however, there is still a problem with the keyboard. When the keyboard is installed in the laptop, several of the keys do not work. However, when I take it out (and suspend it with some plastic) it works fine. I have disconnected the ribbon cable, and taken some alcohol to clean up the area. I have also been able to run the HP diagnostics on bootup, both short and extended versions, and they come back ok. Additionally, I connected an external keyboard and it worked fine. I have searched the forum for this type of question and didn't see it. Has anyone else had this problem, or am I looking at replacing the keyboard?
I currently am running windows 8.1. I do not get any error messages, but I did notice HP does not include a keyboard key test in its diagnostics.
This question was solved.

Hi there @MrKen99
Welcome to the HP Support Forums!
I understand that some of your keys are not working, after some liquid decided to pay an unwanted visit to the board. I am happy to assist you with this.
In my sordid past I have seen some really messed up keyboards, due to similar things, coffee, cola, water, whatever. My most memorable was someone who brought me a computer that was used in a kitchen and was close to a deep fat fryer, and the keyboard was not only coated with oil and grease but a build up of fuzzy dust all throughout the keyboard. In that case I recommended a replacement as the cost to clean it was more expensive than a new one.
Anyway, it sounds as if you have already tried to clean it, but if you did not pop off the offending/non-working keys, the contacts could be "tacky". Make note of the keys that are having the problem and treat them individually. This document shows how to remove and replace keys from a standard notebook keyboard.
Notebook Keyboard Troubleshooting (Windows 8)
If you do not have any success doing that then, I would look at either replacing the keyboard, or using an external keyboard. If you choose a replacement you can look at the service manual for it, and it will list the supported parts.

Keyboard keys dont work in Mac OSx

The following keys suddenly stop working and then continue working randomly: F1 to F7, but the F keys work (eg to show desktop) and also the right (and only the right) shift key.
This does not depend on what software I have running and happens very very frequently.
If I bring up the Keyboard Viewer when the problem exists, the keys also dont get registered on the keyboard viewer.
This is really annoying and happens in Mac OSx, not in Windows - although volume and brightness keys dont work (all the time) in Windows - less of an issue though.
Any suggestions??

I'm having a similar problem. But it is not intermittent, they just don't work.
What can I do to fix this? If I use my wireless keyboard, it isn't a problem. Just when I use my laptop by itself...

Qosmio F750 - some keyboard keys stoped working

Hello
I have a Toshiba Qosmio F750 since 3 months ago. The other day, i just powered the laptop and noticed some keys (a,b,n,enter...) were not working at all. I tried to clean blowing under the keyboard and nothing. Also in the windows booting these keys dont work. Anyone with the same problem?
Someone knows how to solve this?
Is quite annoying having to use an external keyboard with a 3 months old laptop....
thank you!

Hi
I think only keyboard replacement could solve your keyboard button problem.
It looks like the single buttons are faulty and since the single buttons cannot be removed, the whole keyboard needs to be replaced.
Get in contact with an local Toshiba ASP. The warranty seems to be valid and the fix should be done free of charge sorry to say this but it seems you had simply a bad luck :(

Keyboard keys not working?

I am wondering if anybody has ANY ideas for me. It started off the trackball not tracking to the right. I cleaned the TB, and fixed that problem. Then all of the keys went random. The call button went to "y" and "i" all of the time. I did a hard reset (after many soft resets), and that fixed most of the keys. Then randomly the "3/R" key quit working, and the "L" key also quit working.
Any ideas? I am exactly thirty days out of warrenty....
God bless,
John

Hi,
How did you "clean" the trackball?
I guess you've got water damage so follow sdgardne's steps for de-hydrating the device - stick the devcie only (no battery,etc) in a bag of rice for three days (DO NOT REMOVE OR "TEST"!)
If this doesnt work then do an OS reload.
If it still doesnt work then youve got a faulty device and you'll have to go through a repair/replacement.

Keyboard key not working

Hi
I left my mac over the weekend and not use it at all and I came back after the weekend to find that my 't' key isn't working. It works on my wireless keyboard so I am guessing its an error on the key but I have never know it happen to just a single key? I checked and the key isn't jammed.
Can anyone help with how I can fix this or is it gonna be a trip to Apple to get them to fix it?
Cheers
Jack

Keyboard's right arrow key stopped working..
Please give me the possible solutions for this problem..
If this is in warranty you should get it fixed ASAP and if not you will have to get a USB keyboard to test whether or not the fault is the laptop keyboard or the system board connections to verify the problem. If the USB keyboard works fine for all keys then you need to replace the laptop keyboard.
