Toshiba Laptop Keyboard Malfunction

I have a Toshiba laptop A85 - S107 with an "all but dead" keyboard. It usually does not work at all. The indicator light under the F11 key lights up as soon as you turn on the power. If you run your hand across the entire keyboard some times the light will go off and all the keys will work except the z, the /, and the arrow keys. When you press on of those keys the keyboard freezes up and you have to turn it off to get any further response. A USB keyboard works fine. It IS NOT a problem with the keyboard hardware. My boss has the exact same laptop - without the keyboard problem. I took the keyboard off his laptop and put it on mine. Same problem. I put my keyboard on his laptop and it worked perfectly. I started having problems about 2 or 3 weeks ago. My laptop is 2 years old running Windows XP SP2. I have thought about formatting the hard drive and re-installing everything. Any thoughts?

    OK - I made a bootable XP CD using BartPE. I launched from the CD and went into WordPad and I could type all the letters of the alphabet until I got to z. The keyboard locked up. The USB external keyboard still worked fine. It doesn't sound like it would do me any good to format the hard drive and re-install windows. I also ran AV software, Ad-Aware, and Search and Destroy and everything came up clean. Any other ideas? Thanks

    I have a Satellite M55-S325 with similar keyboard issues. Keyboard is dead until you start clacking on the keys. The board starts running on with a period or [ then locks up after a time. Replaced the keyboard, updated the bios with like same new, same prob. Any USB keyboard works just fine. Me thinks is time to replace the system board.......Thoughts?

    I have exactly the same laptop and exactly the same problem. If the laptop stays off for a day, it works well for 15 minutes. If I just reboot after that, it won't work.
    An USB external keyboard works fine.

    My Toshiba Satellite has similar problem. A "^" is inserted to each key strock and makes a undisplayable character or a "hotkey". An PS2 keyboard with a USB pigtail has the same problem. I removed the keyboard(s) from Device Manager, unplugged USB, reboot and did not see any difference. Reformated HD, reloaded XP, and updated to FP3 does not make any difference.

    I do not know the procedure to reload CMOS.

    Any ideas??? Please help.

How do I change a keyboard on a satellite A85-S107 laptop?

1. Take out the battery and AC adapter, unplugged from the wall, enusre the laptop is fully powered off.
2. Remove those screws with a T-8 or Phillips screwdriver.
3. Turn the laptop back over and open it up. Check and see if the Toshiba Satellite A85-S107 keyboard is tucked under any plastic pieces. If so, find them if those plastic pieces are screwed into anything, and unfasten them as well. If not, it probably uses clamps that can easily be removed.
4. Remove the plastic pieces carefully.
5. Unscrew any screws at the top (if necessary) and remove the keyboard itself from top to bottom. You'll notice that the keyboard is connected with a thin, but wide, data cable to the system board at the bottom.
6. Disconnect the data cable attachment of the keyboard which will sever all the remaining attachments of the laptop keyboard with the laptop computer motherboard. To remove this cable, you have to just carefully pull it out from the socket to which it is attached. Then you can lift out the entire keyboard out of the laptop.
7. Take the new Toshiba Satellite A85-S107 keyboard out of the plastic and place it inside with the right orientation, attach the data cable.
8. Refasten the keyboard in place at the top.
9. If you had to remove any plastic pieces, carefully snap them back in and replace any screws you had to remove.
10. Turn the laptop over and replace all of the keyboard screws.
11. Put the laptop battery back in place and switch it on to check Toshiba Satellite A85-S107 keyboard functionality. If everything has gone according to plan, you should be ready to type away!

Hi, 2 of the key pads came off at my sisters house can you give me an idea how much it will cost to get them re-installed it seems they are only the top parts & one seems to be sticking


You really can't purchase just the keys alone, you usually have to replace the keyboard itself. My company sells the keyboard for $69.99 for the OEM and $59.99 for compatible keyboard.

Problem with display

It's the inverter you need to change.
Usually that's the symtoms when it goes.
You can usually find one on ebay or amazon or wherever it's not very hard to change either.
Just has a couple of plugs and they are affordable.

You might have a short in the jack that you plug the power adapter into, which means that it is only sending power to the laptop but not to the battery. Your batteries are dying because they can not be charged. You might have to take it to the shop. Check and see if it is still under warranty.
