After BIOS update numpad on my Satellite C850 does not work correctly

My numeric keypad started to go crazy. What can I use are "0.369* - + button"home"end touches PGUP and PGDN.

The keypad light is on and I can't turn it off. whenever I do what it s like I m by pressing the FN key and whenever I press NUMPAD 1 it always typing gibberish words when I press NUMPAD 2 he does what than done F12 key and so on for numpad 4,5,7,8

All this happens after I updated my BIOS and has never been a spill of liquid on the keyboard.
Any idea on this freaking problem?

Hello

I can't imagine that this problem could be linked to the new version of the BIOS.
Maybe it of a simple bad luck that this keyboard problem appeared after the BIOS update.

From my point of few, it looks like malfunctioning hardware keyboard.
But to confirm this diagnosis, you should try workarounds.

* 1 * workaround: first enter the BIOS and set its default value.

* 2nd * solution: disconnect the power adapter, remove the battery, hold down power button / stop along 30 sec. Finally, reconnect the two devices.

* 3rd * workaround: connect the external USB keyboard and test functionality.

In case the USB keyboard would work correctly, the problem is related to the fault of the internal keyboard.

  • Drive CD/DVD of Satellite P100 does not work correctly

    Play dvds on windvd or CDs on Media Player results in his nasal and photos. Sometimes both play very well but then any attempt to enter a new menu or jump titles causes stuttering again. Tried a system restore that solved the problem initially but now it is picked up. Strangely, change the volume sometimes seems to invite the reader to work properly, almost as if he's slow and then use other controls somehow turns it.
    Is it a hardware problem or software?
    Not a computer expert so if you have a solution please explain as simply as possible.
    Thank you very much

    Packer of creative cloud in creating a package that I can install do not.  He goes through the motions, download all updates, create setup file, but it does not work despite the fact that there are no errors in the log files

    After hitting my head against the desk to repeatedly create packages, try on different computers I have finally found a solution.

    These packages have been copied on an external drive, if I try and install from the external drive, which is a common practice, it fails.

    If I then copy this file pkg from the outside, to the computer I install, then run it, it will to and moved very well.

    That is mind-boggling stupid, because it's rare that you have to copy the file into any computer, it is less always installed off the coast of externally, and many people in the company are pushing on the network and the management of the suites so there is a serious problem in Adobe package manager if this is the case where it cannot manage the Middle installed offshore.

    I hope that if anyone else is having problems so it suits.
