Some keys on my laptop dont work

The keys m, c, v, x and apostrophe dont work. Pressing comma also works as F11 at the same time. PGUP and PGDOWN work improperly. Only right control works. Pressing space gives me bracket and space - [ [ . Sometimes it will repeat a key like thiss one or qq. Somehow G is connected with F7 which asks me for caret browsing. F2 is connected with S, F4 with D, F11 with comma and F12 with a dot. Arrow keys only work on a single stroke (holding them wont move the cursor). I am trying to get help but no one was useful so far (telling me to try on-screen keyboard, or buy a desktop keyboard for my laptop is not helpful at all).

I dont know how to fix. I did virus and spyware scans, fixed the registry with registry mechanic, in safe mode the issue is still there and I dont have any restore points. What can I do? I have a vista 32, toshiba satellite A500-13F laptop.

And I didnt instal anything that might affect the keys and I dont think its dirt, I keep it clean (without using water, just dry cleaning). The keys just didnt work anymore.

I checked in device manager and theres no yellow exclamation mark. I tried to uninstall and reinstall the driver, but the issue is still here. Now I am trying to download a driver if its anything better but I cant find anything. The issue must be digital rather than something physical with the keyboard, because all keys act the same. Whenever I press G it asks me for caret browsing, even if I checked not to show that dialog box again. Whats wrong?

    Ok, thanks. I am still wondering if there was any possibility of any liquid, but if it is then I am wondering why do keys always act the same. Comma will always act as F11 too, which switches IE or FF to full screen. I will try with a new keyboard, but its not a big issue anyway. I am planning on buying a new laptop while this one will now be good for videos.

Trying a desktop keyboard is useful for determining if it is a keyboard problem or a software problem. This usualy happens if some liquid has gotten into the keyboard, but you said thats not possible. Try to boot into bios, the first screen that pops up when you boot, on a toshiba it is usually pressing F1 or Del. then if your Arrow keys don't work there, you need a new keyboard.

    The reason it acts that way is the pathways are bridged with the liquid, so every time you press a key it follows the new pathway. I do not agree with buying a new laptop unless you want a new laptop. You can buy a brand new keyboard on ebay for under $20 and it is very easy to change a keyboard, and many resellers offer instructions with their keyboards.

Hello hklotus, hi, your keyboard is totally bad, the mcvx keys are open, this could be that SOMEONE may spilled liquid on your keyboard, you may not know it. I agree with the other experts advice, its either you replace your laptop or buy and use a USB external keyboard. you choose.

there should be a boot menu command at start up just like you entered the system bios, i believe the e machine boot command is F12 that will give you the opportunity to boot from what ever you want on that boot only. so in your case of course you would scroll down to cd and hit enter. press any key to boot hit any key and boot.

Light is in lid,top centre,instructions say to pressFn and Pgup keys to switch it on,no pressing combination makes it work.I need the night light facility

Quote from the R50e manual:
"Fn+PgUp Turn the ThinkLight on or off.

Note: This function is supported only on the
ThinkPad computers that have the ThinkLight.
The on or off status of the ThinkLight is shown
on the screen for a few seconds when you
press Fn+PgUp."
You might try and reinstall ThinkPad Hotkeys Features Setup or something similar to that.

Hi, "I suggest that you try reconfiguring the way the Keyboard functions. Click on the Start button, in the [Start Search Window] type: keyboards; the "Keyboard" will appear in the shortcut menu. Next, select to open, make all the changes to your specifications, "Apply and OK" all changes. After you are finished, Restart the Computer. If this helped; let me know by giving a "helpful rating," thanks.

Go to the control panel and set up your mouse. If this doesn't fix the problem, take the mouse apart and blow the dust out where the wheels with slots are. There is a small eye that detects movement in the wheels. If that doesn't fix it, the mouse needs replaced.
