My computer keyboard starting doing its own thing

I have a Satellite M35X. I use this laptop for work and personal use. It was purchased January 2005, so it’s 18 months old. Recently, I purchased Scan Disk to back up my documents file on a chip that you can carry around your neck, — I don’t know the technical name for what they call this. The day I plugged this in to a USB port, 20 minutes later when I was working in Microsoft Word, my computer keyboard starting doing its own thing. If I hit the shift key, it would take off typing “n” across the page or the backslash symbol. It would reboot but I could not get past the password screen. When I started to enter my password – the touch pad still works well in moving the cursor to an area. It would permit me to enter 3 characters, then it would return wiping the display out and back to reentering again. I purchased a new keyboard and replaced the old. The same thing occurred. I purchased an external keyboard, and unplugged the laptop’s keyboard. For the first 4 hours everything went well, then it did the same thing. When I went into Word it would start typing capital “b” across line upon line. Hitting Escape did not stop it. Holding down the backspace key just caused it to delete the last typed letter, but as soon as it was released, it would continue across the page. Sometimes it would type three characters on a line then return and start with a backslash symbol and type a couple more alphabets on that line, then return and start with a backslash again and a few more characters, return again, and do the same over and over. The alphabet typed on the lines were not always the same – it liked a capital “A” and “n” quite often. When you then go into Microsoft Explorer it will not let you type in the search bar or the address bar but inserts backslashes, continual, never ending Since the laptop keyboard has been replaced, and an external purchased and plugged in, it is not the keyboard, but must be something in the computer. HELP! Any suggestions????

According to the description you’ve provided, I would assume that the keyboard is bad, but you already replaced it. That is a very strange problem. I assume that it might be a software problem.
You can try to reinstall the keyboard drive. Open the device manager and find the keyboard line. Click on the plus sign to expand it. Right click on the “Standard 101/102-Key or Microsoft Natural PS/2 Keyboard” line and click on uninstall the driver. After you reboot the laptop, Windows will reinstall the driver automatically. Try it first – it might help.
Also you can try this. Revert the operating system back in time when the keyboard was working properly. You’ll have to use the system restore utility. Go to Start – All Programs – Accessories – System Tools – System Restore. Choose date and time when the keyboard worked fine and run the restore. This process will revert only system files and you shouldn’t loose any personal data.
If it still doesn’t help, you can reload the operating system from a recovery DVD. It will take the laptop software back to original factory defaults. When you re-image the drive all data on your hard drive would be erased. BACKUP all important files before you run the recovery DVD. This process should eliminate any software related problems.
One more thing. Try to re-flash or update the laptop BIOS. May be the BIOS is corrupted and it causing the keyboard problem.
If it still doesn’t help, then I would assume that the keyboard controller on the system board can be bad and the system board has to be replaced.

  1. I just wanna say that Toshiba is telling me that my computer wasn’t covered with the xtended warranty but the Toshiba M35X IS so make sure yu get your computer fixed for free – person who started this thread

  2. update on the toshiba m35 keyboard issue
    took my laptop to the service agent Toshiba agent told me to on Dec 19th called today to find out status and they said it was NOT under the extended warranty. Called Toshiba and they gave me the runaround.
    Essentially telling me that they never said I was under the warranty..
    I pushed hard and finally got the customer service person to admit that they may have given me the wrong information. I’m to call tomorrow and speak to a CS supervisor.
    This the last time I’ll get a Toshiba anything you can rest assured. I’ve spend 4 months trying to get this resolved and spent over 200.00 so far
    Now the repair shop wants $99 for a new keyboard and $65 to replace it.
    I want Toshiba to cover this since they sent me to Concord (another county) when I might have been able to fix it for less rite here in SF.
    UGH (i thought it might be too good to be true)
    In answer to laptop freaks question about the two techies who told me there were other issues – one had me replace my hard drive as they said it was failing they also said it was spyware and even showed me the malware his sweeper cought. told me to get rid of norton – they sold me Trend which I’m using.
    The other one ( a Toshiba repair shop in Berkeley) said there was nothing wrong with my keybboard. He didn’t know what it was.

    It’s very unlikely that two different keyboard on two different laptops have the same issue. I don’t think it’s a hardware issue. Virus? Possible. Maybe you installed the same infected file on both machines.
    What if you boot the laptop into Safe mode or use an external keyboard, the same problem still appears?
    Do you remember when the problem started on the IBM laptop? Try reverting the operating system back to that time using the system restore utility, it might help to get rid of the problem at least on the IBM laptop. Use SpyBot S&D utility to scan the laptop for spyware.

  4. Hi,

    I have 2 laptops – an Acer TravelMate and an IBM R52.
    The problem in both is that the keys for typing @ and ” have swapped…. i.e., I need to press Shift+2 to get the character ” and Shift+’ to type the character @ !!!

    This problem emerged first with my Acer laptop and has just recently spread to the IBM one!! That kinda confirms that it’s a software issue…..or a virus??

    Please help!!!

  5. GREAT NEWS for the M35X owner up there
    Our laptops were recalled for a static electric something or other and in the process all M35X’s have an extended warrantee…SO we can take our laptops to a Toshiba repair place (call toshiba and they;” give you the name and address of one near you) and they will fix our computers for free.!!!!
    labor and parts…
    I just happened to find out about it as i scrolled thru some stuff on Toshiba’s website you might want to check it out – it’s a class action suit.
    So hopefully I will find out real soon what the problem was….but you better get your butt in gear and find out if you qualify

    Cam Muir,
    All keyboards are different and I don’t have any instructions for assembling it back together. Sometimes I get customers like you, they bring me parts of the keys in a plastic bag. Here’s what I do in this case. I carefully remove the cap from a working key to see how the frame is assembled under the key. Carefully pull it up until it snaps off the frame. You want to remove just the cap, so the frame stays in place. After that you assemble the frame from a pulled key the same way as it assembled on a good key and then snap the key cap back in place.

    I went to two different techies and they both said nothing was wrong with my keyboard -( it works with an external one)

    What did you mean by that? The laptop works fine with an external keyboard?
    If the laptop works with an external keyboard, it doesn’t mean that the internal keyboard is just fine. I would assume that there is nothing wrong with your software, but you still might have a faulty keyboard. Do you get any beeping sounds on startup? May be you have a stuck keyboard key?

    I have a large problem and no body seems to able to solve it. A have a Toshiba Laptop model A105-S2061 and let someone use it for the weekend and guess what there is a password in the bios and I can’t get it out?
    Ok- before everyone tells me about the fixes, here is one little twist, there is no parallel port!!!
    Now, I have tried them all that I have found, even used a usb to parallel cable to no avail. Now guys I am all ears for suggestions??

    Last night my cat jumped up on my desk and stepped onto the keyboard of my laptop. As I lifted him off he swug down his paw and stuck one of his claws under a key (#5+1) and pulled it off. I have found three parts: the key, a little rectangular frame and what looks like a tiny toilet plunger. Can you tell me how to replace the parts so I can once again use this key?

    Many thanks!

  10. Ijust read the first entry and my mouth fell open
    I too have a Toshiba M35 and have been having the same issues.
    When I typed OK – as I typed the K the O disappeard. Then as I typed whole sentences disappeard. At the same time N started to give me an H after it and then the F gave me a $ in front of it and then the keyboard stopped responding altoghether. I went to two different techies and they both said nothing was wrong with my keyboaard -( it works with an extenal one)
    Then I read in the microsoft knowledgebase that pressing the F12 or F11 keys at the same time might fix the problem…after a while it did
    BUT then like a bad movie the keys started to act up again – the very next day the keyboard stopped working.
    I use flash memory stick too but have always used one and i never had any problems
    HELP – my computer is around the same age as the other M35
