    hi everyone,
    i have changed cpu to tk-57 to tl-68
    i got just blank screen no post or no splash screen of bios!
    just laptop restarts once then shut down itself.:S
    i can hear dvd-rom and hdd voice but fan doesnt work.
    tl-68 is dm step like tk-57.
    it seems to be supported.
    Should i reset cmos.?
    is there any dude who know where cmos jumpers are in motherbord.
    i saw the cmos battary location on picture.
    There is very hard to get for me.
    Thanks...
