    This is an older Compaq laptop, Evo N105v with a P4m CPU and the latest BIOS. Two issues, possibly related:

    Keyboard issue:
    Power on the laptop, hit F2 to enter BIOS and it won't go in BIOS, whether you hit it once or tap it like crazy. If I boot off a boot disc that leads to a text based command line, 2/3 of the boots it won't read the keyboard whatsoever unless you reboot and 1/3 success on reading keyboard. An external keyboard will work fine, every time. If you set BIOS to support either onboard only or onboard and external keyboard, it has no difference.

    Slowdown issue:
    An example of this, while installing Windows from an OPK install, during the WinPE boot the system will operate at extreme turtle speed... unless you hit a key on the keyboard and it operates normally. After a reboot, if you don't hit a key at some point, it will run at turtle speed. By turtle speed, I mean the system will take two days of full running to install Windows from CD.


    Since experiencing these problems, the laptop was completely dismantled and we cleaned the CPU heatsink and applied some fresh thermal compound as the relation between keyboard and CPU speed wasn't noticed until after the system was put back together. Taking the laptop completely apart, to access the CPU, had no effect on solving either of the above.

    Anyone who's intimitely familiar with this specific or similar models and has some experienced insight, it would be appreciated! Thanks in advance.
