    Hi all,

    I'm currently in the process of repairing a Toshiba SA40-261 laptop of a friend of mine.

    He was complaining about the clock that kept resetting itself, since he uses it stationary because of a dead battery my first instinct was to replace the RTC/CMOS battery.
    I fixed a new batterypack for him and he changed them, but now the laptop doesn't boot anymore.

    It turns on (power light) but there's no screen activity, no backlight, no disk activity, no fan activity and no beeper activity at all!

    In an attempt to reduce the problem factors, I've removed the WiFi card, the harddisk. Replaced the RAM and even tried it with the chassis removed (no screen, speakers, multimedia keys etc.)

    Has anyone here seen a situation like this?
    Is there any way to reset the CMOS (if this one could be garbled)?

    Or could this mainboard be bricked?
