Satellite C850D-11 q - keyboard and the Touchpad does not

The laptop is a little more than a year and worked ok until recently.

Symptoms were the keyboard and the touchpad does not not on page 8 of windows logon. Pressing power to put the laptop into sleep and pressing still often got their work.

He progressed to the keyboard and the touchpad works do not randomly points while the use of the laptop.

Finally cleared the HARD drive and restored windows 8 alone, the laptop still BSOD quite frequently - refuses to install the updates required for 8.1 and the keyboard and mouse often do not work even in BIOS Setup page. I reinstalled the RAM and HARD drive.

Short of ideas, the keyboard and the touchpad work and so I guess that their connections are correct - but often they just stop.

Any ideas appreciated?

Thank you

Hello

> Finally cleared the HARD drive and restored windows 8 only
I hope that you created before Toshiba recovery disks you have formatted the system.
Did you?

The recovery disks will allow you to reset the laptop to factory settings; on the same State as at the first day of the purchase.

> First symptoms were the keyboard and the touchpad does not not on page 8 of windows logon. Pressing power to put the laptop into sleep and pressing still often got their work.
Well, usually the keyboard problems are not problems system or software as the keyboard driver is part of the system and an additional installation of some drivers is not really essential and necessary.
That is why in most of the cases the keyboard problems could be the causes of physical problems.

However, after using the recovery disc and the parameters of the laptop back to factory State, both parties (keyboard and touchpad) should work perfectly.

> the BSOD laptop still quite frequently - refuses to install the updates required for 8.1
BSOD doesn't look very good. As mentioned above; parameters of the laptop back to factory settings should solve all the problems in the system. In the case where the BSOD appears even if the power has been turned back to factory State, a hardware problem could be the reason for this.

I had also some problems with the update 8.1 Win. The system to win 8 could not find the Win 8.1.
But the reason for this was simply. I had to install all updates to Win 8 and had to update the State system before trying to update to the next level following 8.1 Win

So, what can I say: I will try to put the laptop initial configuration using the recovery disk.
Then I would try to get automatic updates (a few reboots were essential too). After that, I would check the functionality of the keyboard and the touchpad. In the case where them parts would not work, I would contact the service to check if the two pieces.

  • Recovery of the Internet and the Touchpad does not

    Hi all!

    I tried to format my Macbook Pro (2015 start, 13 "), so I wiped the disk with disk utility.

    Now, I'm the restart with CMD - R and a globe appears. I know that it means that the computer is trying to reboot from the internet, but I have to choose my Wi - Fi and insert the password.

    The problem is: the touchpad is not sensitive, so I can not perform the procedure. I also tried a keyboard and a USB mouse, but it does not work either.

    Thanks to anyone who responds!

    Release the SHIFT key when you see the gray Apple logo and progress indicator.

  • When install Vista Home Premium computer hangs on the language selection screen. No visible cursor, the keyboard and the mouse does not.

    Hi, when I try to install vista that Home Premium 32 bits on the computer of my son, through the installation of loading files with the gray bar at the bottom, then goes to the screen language selection, at this stage, I can not select anything using the keyboard or the mouse. There is no cursor visible. Keyboard and mouse both work fine in the bios and on other machines. Have used other keyboards and mice on the machine in question, but that makes no difference. Tried another copy of vista, no difference. Tested on Windows 7 install and everything works fine!

    Very confused, thinking that it must be a driver problem, but how about him? Any help is appreciated!

  • Satellite Pro L20 - right button on the touchpad does not work

    I have a Sat Pro L20.
    When I press the right button on the touchpad, nothing happens. The left button works fine.
    I checked the properties of the mouse left button is set as the main click with the right button, defined as the secondary click.

    Thank you.

    Hello

    Maybe the touchpad button has a physical malfunction.
    But first of all, you can try to reinstall the driver for the touchpad. Check if the resettlement will change something. But the truth; I don t think this will solve the problem. Anyway, try is free, you know.

    But if that does not help so I think you need to replace the touchpad.

  • Satellite A30 - electric light flashes and the battery does not charge

    Hi guys,.

    I have the model above and recently, when I plug in my power cord to the back of the laptop instead of the usual constant green light loading, the indicator flashes and the light orange low battery always flashes as well.

    I have checked the plug, unplugged the power cord from the laptop and plugged back again but does not help. A few times it started loading so everything went well and now he again refuses to load.

    Any suggestions how I can solve this will be highly appreciated.

    Thank you.

    Looks like a hardware problem

    Usually if the power light blinks then it does not sound good because the LED provides an error code which can be read by a technician for laptop

    But before you will contact the technician for laptop for help, try to do it:
    Remove the battery and unplug the AC adapter from the portable computer
    Wait about 20-30 minutes and then reconnect the two parts.

    Then try to turn on the laptop

  • Problem starting el capitan (sierra) - built-in keyboard and the mouse do not respond

    Hello

    I have a 2015 macbook pro (SSD 256, 16 GB of RAM last el capitan updated) with a wired problem.

    I use it mainly to a cinema monitor and I use wireless keyboard and mouse (office installation program), and of course as a stand-alone laptop when I'm not at my desk.

    When I put the laptop to sleep, everything works fine when I wake up.

    but, if I'm away from the office and I have to restart my laptop, here is the problem.

    The boot process is very very slow, there is no edge, and when I finally have the screen to unlock the safe, the keyboard and the touchpad do not react. Actually, that's not exactly true, they are so slow that they are unusable and get caught quickly, all gel. So I can't unlock and complete the boot. My laptop is unusable ;-(

    At this point, I get a message that if I forgot my password I just need to reboot by pressing the power button, and I'll be able to reset it.

    When I do this and aprΦs the dΘmarrage that more slowly than usual but ok, I get another screen with several options of problem solving. One of them is "keyboard not responding do not. When choosing this one, it asks if you want to remove safe. I tried and everything was back to normal.

    later, I delivered safe and I had the same problem again. I did the thing to be able to restart again and improved to sierra in the hope that it would disappear. However, the problem is still there.

    I thought I could try to restart my office to see if my keyboard and wireless mouse would still work. Indeed, even if responsiveness was not normal, I could unlock and fill the chest.

    I have the impression that my laptop always "believe" it is on my desk, linked to my screen (probably the reason why I don't hear the Bell) and to my wireless K & M.

    It's really annoying and I hope someone has a solution.

    Thank you very much

    best,

    Alex

    I'm having a similar problem with macOS Sierra which I didn't have with El Capitan.  I can possibly move the cursor on the power button and turn off (no), but I must be patient because the keyboard and trackpad are only for a fraction of a second, which only allows me to move the mouse slightly.  After he stop and start back up, everything is perfect until I tried another reboot, and then I'm back to the beginning.

    I tried to reinstall the operating system, reset the SMC, resetting the NVRAM, reboot in SafeMode... nothing worked so far.

  • loss of function of the keyboard and the touchpad

    I am a rural small repair shop and received a HP/Compaq Presario CQ60-615DX to repair the loss of function of the keyboard and the touchpad. My first thought was that the Ribbon connectors came loose. However, when I first turned it on, the keyboard worked to enter the Windows password. Once started, the keyboard would not work. My client had a major sale/repair company and their solution was to install a keyboard on the screen and use a wireless mouse. I started my research in this tthinking of problem that perhaps it was caused by malicious software. Fortunately my client gave me the AC adapter while I was looking for input on the laptop voltage. It wasn't on the outer label, so I removed the battery. I reinstalled the battery and was amazed to find that both keynoard and touchpad work now.

    What could have caused this loss of function and why would be to remove and reinstall the battery solve this problem?

    It's probably that the battery actually acted as a hard reset.  A hard reset has the effect to remove remaining current EEPROM and other devices on the motherboard.

    Best regards
