Certain keys not working after formatting......

I recently formatted my laptop and reinstalled Windows XP and all the drivers.
Everything is fine except 2-3 keyboard buttons are not working (@ and \ keys are not coming). It is due to wrong/missing driver or some other setting is there?
Do laptops need key board drivers? I installed all the drivers I had in the bundle.
Any ideas what it could be for Compaq C794wu? (XP)
This question was solved.

I mean, the keys are working, but the output is different.

Some keybaord keys not working after suspect virus on Tecra A

Apostrophe, delete, semicolon and end keys not working after a suspected virus attack. I found record of the same problem on the net but apparently this guy fixed his problem after he found scroll lock or num lock on.
This is not the case here but there is something going on with numlock - register shows 2 and not 0. change to 0 but when reboot back to 2 again.
Suspect changed back by bios. I thought i couldnt get to bios because DEL key not working but found ESC works.
Tried to reset default values for bios but then cannot save and exit as this required the END key to work.
I was running XP at the time of the (suspected) attack and could not rectify the problem so put the computer back to the OEM status which i hoped would help - it did not, same problem so rather than install all the software on the computer again with XP i upgraded to Windows7 - fresh install.
Still keys do not work - it was a real pain to start with as my computer was set up to ctl+alt+del to log in and i had to do this with on screen keyboard - XP - this also showed that numlock was on before and after windows boot.
The reason i suspect a virus - my wife was watching one of her tv shows on line from home country (another toshiba laptop) and i needed to use that laptop for something else so i asked her to use mine - later on we turned the laptops off and in the morning turned tham back on again, the other laptop with AVG virus protection flagged several hits and this one with (FAMOUS and completely up to date) Norton flagged nothing - once i got into it using on screen keyboard.
Problems with this computer was found after scanning with a different antivirus.
Anyway - i am left with 4 keys that do not work on my keyboard (actually they did work after i logged into the computer for the first time but i had to hold them in for a long time - and then next time i rebooted, not work at all and havent ever since)
Any assistance here would be greatly appreciated, i have been working on this all weekend with no joy at all.
Thanks in advance.

Thanks Xardas,
I have essentially done both - tried Toshiba OEM status found on a small partition of the toshi hard drive - no good - then did a fresh install of Windows 7 - still no good
You know - as cunning as it sounds - i cannot reload the default settings in BIOS as it requires the END key to work so i can Save & Exit - all i can do is Exit Without Save - i sort of feel snookered at the moment.
Toshiba got back to me today and said that i have tried everything they would have (yeah for sure) and to take my machine into a service centre for a hardware check - yeah right on boys!
Check out this guys post below found on Kioskea.net - getting close to a year ago...

Hi there, I was hoping that you might be able to help me with the problem that I seem to be having with my Toshiba Satellite Laptop Keyboard too. For a few days now I havent been able to use a few of the keys on my keyboard, including (1) delete (the backspace key is still working though), (2) colon/semicolon, (3) apostrophe/quotation marks and (4) end (the home and PgUp and PgDn keys are still working though). Any suggestions?
Identical to my problem....obviously this guy had the same problem as well...see below - same thread.
yab - Feb 9, 2010 4:47am GMT
hi did you ever figure this out? i have the same exact problem...
However, i was not able to solve my problem the way this guy did - my scroll lock is not activated - it seems to work ok (on and off) i tested it using Excel to move around the cells.
yab ms ml - Feb 9, 2010 7:57am GMT
Nevermind. For me it was scroll lock. My apostrophe, semicolon, and delete keys are alive and working again. I hope you have the same easy fix.
Incidently - never hear from the first guy again - probably ended up being his scroll lock.
all sugestions welcome - sorry my smily face has no eyes -) guess why!

6630: Certain Keys Not Working

For some reason, my Nokia 6630 has certain keys not working. Actually, sometimes they work and sometimes they don't. I doubt it's a cover problem, because even when I take it out, the keys still don't work.
The "1", "3", "C", Left, and Up don't work at all, and it's annoying. Some help, please?

The phone is too old and I think it has no FW upgrade in NSU.
I guess this could be a hardware fault. Better if you go to service point.
But before that have you tried a hard reset?*#7370#.
[It will clean up the phone memory, so better back up by PC Suit).

Liquid spill on keyboard. Certain keys not working. Any inexpensive repair? re

Water spill on the keyboard of my Mac Book Air. Now certain keys not functioning. A Mac friend suggested submerging in rice upside down to dry out. Didn't work. Warranty expired. Help!

Yes, the "magic rice trick" doesnt work.
inexpensive repair? No.
Liquid spills, why your MacBook chassis is a one-way valve for spills
After a substantial spill many people will turn their notebook upside down and shake it, not only does this not work, but it spreads liquid havoc throughout your machine and makes things often as bad as possible.
The keyboard itself acts like a one way valve in the case of a substantial liquid spill. While liquid pours into the bottom chassis easy, it does not come out easily at all, and in the case of any spill, most of it will not come out by turning it upside down. Disconnect all power and contact Apple for diagnostics and repair.
Do not attempt to, after a spill, ‘dry out your MacBook’ and test it
After a spill most people invariably try to “dry out” their notebook by various methods, including hair dryers and otherwise. This both does not work, and after a substantial spill of any magnitude, even if the liquid was water, residue is left behind.
There are additionally many very tight places inside your notebook where liquids will linger for a very long time, and cause corrosion or worse.
Immediately unplug your notebook and contact Apple for in shop diagnostics and parts replacement.
In the case of very minor spills people will “dry out” their notebook and feel success that their notebook is working ok, however invariably in nearly all instances after 4-14 days an error / fault pops up and is usually followed by more.
In case of a spill, damage estimates are impossible,.....anything can be fixed, without question.......the question is cost.
contact Apple for in shop diagnostics and cost estimation ....possible parts replacement.

Re: NB200-134 - FN key not working after upgrade to Windows 7 Ultimate

My FN keys of NB200-134 is not working after upgrading from Windows 7 starter to Windows 7 ultimate. I tried installing every drivers found on Toshiba website for my lappy but still it does not work.
Help please

Hi asalamk,
The FN keys are controlled by Value Added Package and Flash Cards Support Utility. I think you have forgotten to install these tools
You should check the Toshiba page again and download both tools. Start with installation of Value Added Package then restart your notebook. After this install Flash Cards Support Utility. Once again restart and all FN keys should work properly now.

Glide pad will not work after formatting g60-630ca

Can somebody help? my glide pad will not work after downgrading to xp. The pad works itself for the mouse but then the scrolls on the side will not. Please help...

You need the driver. It is a Synaptics Touchpad and you can use this driver:
Synaptics
Here is a link to the General XP Downgrade guide which has a link to all the drivers you need under "Moderate models:
XP Guide
The touchpad is hard because Windows does load a basic driver so it does not appear with an error in Device Manager, but the "real" driver is needed for advanced features like scrolling. Be sure you have all the needed Xp drivers, by the way.

Certain keys not working on Equium A200-196 after Windows 7 update

Hi all, I've just upgrade my partner's laptop (a Toshiba Equium A200-196) to Windows 7 after initially installing Windows XP on it (it came with Vista).
After the XP update, I noticed certain keys weren't working. I can't remember the process I used to fix the issue, but fix it I did, and they were all soon working perfectly. So it was a software issue, rather than hardware. I think it may have had something to do with the FN key - but I can't be sure.
Now I've just upgraded the same machine and I have exactly the same problem. The keys that don't work are Backspace, W, P, F, H, K and L.
Can anyone help please? I've tried reinstalling Win7 and the problem is still there.
Many thanks,
Andy

>The keys that don't work are Backspace, W, P, F, H, K and L.
These keys have nothing to do with the missing software.
Indeed, the function key (FN key) needs an installation of particular Toshiba utility / software to get it working but the Backspace, W, P, F, H, K and L keys are common keyboard keys which dont needs any special software.
Therefore I think the issue is hardware related: simple keyboard malfunction.
I guess all these keys would work properly if you connect and use external USB keyboard.

Certain keys not working envy dv7-7304tx

My keyboard will occasionally lose the ability to register certain keys when pressed. In particular, the top row of number keys will frequently stop working. For instance, at the moment the five, six and dash will not work, and fifteen minutes ago none of the numbers in the top row would. The right-side number pad also will occasionally not work. After a short time everything will work again normally, but it happens pretty frequently and can be very frustrating if you need some work done in a hurry.
As I write this, I've tried the 5 and 6 keys and they're working now, but when I started to write it they would not. Has someone else had similar issues? Is it the hardware or something I can address myself?

Keyboard wireless key not working after upgrading to windows 8.1

Hello,
I am having hp pavilion dv6-6165tx notebook, where keyboard having a wireless button that turns ON and OFF all wireless devices, After upgrading to windows 8.1, HP Connection Manager is not getting installed, as well as Key is not working, key color turns red and white but no action is performed.
Kindly suggest me some solution.
Note: HP Doesn't provide drivers for windows 8/8.1 ONLY WINDOWS 7 for hp pavilion dv6-6165tx.
Thanks.

Hi @Jayesh_Bhadja ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion dv6-6165tx Notebook and the Wireless keyboard not working correctly. Here is a link to troubleshoot the keyboard.
The HP Connection Manager is something that is for Windows 7 not Windows 8.1. I would uninstall this from your Notebook. Here is a link to the HP Support Assistant if you need it. Just download and run the application and it will help with the software and drivers on your system that need updating. It has a troubleshooting tool in this.
Make sure all your updates have been completed. I would try restarting my Notebook a few times.
If that does not help I would uninstall the keyboard from the Device manager.
Thanks.

AltGr key not working after upgrade to Xorg 7.3

So, I upgraded to Xorg 7.3, and everything seemingly worked fine.
Then I tried writing an e-mail address, and pressing AltGr+2 which should give me an (at) symbol didn't work. After fiddling about abit, I concluded that AltGr did not work at all.
I tried the suggested solutions in the wiki, but none worked for me. I also tried setting Option "XkvVariant "nodeadkeys", but no luck there either.
Here's the keyboard section of my xorg.conf:
Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "CoreKeyboard"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
Option "XkbLayout" "no"
Option "XkbVariant" ""
EndSection
This worked like it should before the upgrade.
As you may have noticed, I have a norwegian keyboard. And if it helps, it's a laptop keyboard - I have a HP nc8430.
Pressing and releasing AltGr in xev produces this output:
FocusIn event, serial 28, synthetic NO, window 0x2200001,
mode NotifyUngrab, detail NotifyAncestor
KeymapNotify event, serial 28, synthetic NO, window 0x0,
keys: 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
I'm not entirely sure if this is relevant tough.
Any help will be greatly appreciated.
EDIT: I should perhaps add this:
I'm not using a composite manager like Compiz or Beryl, and I do not have composite nor AIGLX enabled in my xorg.conf.
I'm using the fglrx driver.
Last edited by sunn (2007-11-07 16:28:46)

It seems the problem has resolved itself. I did a pacman -Syu today, and although only libsamplerate was upgraded, my AltGr key functions properly again. Kind of weird, as libsamplerate seems to have something to do with audio.. But hey, it works, and I'm not complaining.

Keyboard delete and caps lock keys not working after update

Shortly after a windows update two keys, delete and caps lock do not work. I have tried the following
1. system restore..it says it cannot restore as a file is missing. I have used this function before without any problem.
2. Update key board driver (standard PS/2)..it says latest version is installed.
3. Uninstall and reinstall.
4. Reset using the remove batteryt hold down power key option.
The caps lock and delete does not work in Notepad or MS Word.
It seems unlikely that the two keys themselves are damaged as it is unlikely that they would both fail at the same time and the problem after the windows undate is suspicious.
I am using Windows 7 Home premium on a 64 bit HP G62.
help appreciated as ever
thanks

Certain keys not working. (backspace, brightness, volume)

Recently, the keys on my Macbook Air (mid-11') has not been working properly and I'm unsure as to why this happened. I noticed in the keyboard viewer that sometimes when I press the arrow keys or such, the fn keys stick and doesn't unstick until i use my cursor in order to click on the key. The keys such as the delete, brightness settings, and volume are not working as it should. Sometimes it does, other times it doesnt not. For example, my delete key now only deletes from the left to right. Brightness settings only work when I change to setting to when I hold FN to use f1 f2. My volume settings randomly switched me to dashboard and desktop 2. It should be noted that everything works fine when i type, delete, etc when I restart the computer and go

Satellite A350 - FN keys not working after Windows 7 installation

Sorry for my bad english, i am forum Portugal and i don't are very good at english.
1 I installed Windows 7 on my pc, installed the drivers 7 and FN was to give. However I had another problem and had to format the pc again, now install everything again and functionality not the FN.
2 Without the drive functionality that is FN + F6/F7 brightness works. But with the drive not installed anything. It seems they are in conflict.
3 The bar at the top of the screen that appeared no longer appears. But if I go to Start -> All Programs -> TOSHIBA -> Utilities -> Settings for TOSHIBA E-cards. With it open, squeeze "Allow the mouse to show the cards" and they appear at the top, as hidden. But just gives me no way, I wish to give to the FN.
Anyone know how this is resolved?? It gave me immense way and even have tried everything, installed everything, there is nothing to block the FN key? A feature that blocks this key?? Please help me.
My PC as it says in the title is Toshiba Sattelite A350D 10Y PSALME....

To enable Fn key functionality, you need to install:
TOSHIBA Value Added Package (v1.2.28)
Utility Support Driver for Windows 7 (v1.0.25.5C)
If you installed Vista version of those packages, it may not work properly.
You need to Windows 7 versions specifically for the A350
