Hi all, can anyone tell how to reset my CMOS to factory defaults? My laptop (Compaq Presario V4000) is dead, power led lights come on but no POST, I am getting the BSOD (black screen of death). I verified for a faulty RAM but they ok, in fact if I try to power without them gives me the beeps of not having RAM. Now i need to reset the CMOS but do not know how, found the RTC Battery and removed it for a while, but that did not work. Looking to see if there are any jumper to short out to reset the bios like on regular motherboards but do not see anything. Thank in advance.
