Help anyone,\n\nI just put a new SD11 mobo in a Compaq 5900Z, replacing a OE version of the\nSD11 that I thought was bad. It would not reboot. (tries to but would seem\nto go into sleep mode instead) Anyway, SD11 was cheap on ebay so I got one,\nput it in and, viola, it does the same thing! So I cleared the bios setting\nwith the jumper, rebooted, and it still goes into sleep mode. (I'm not sure\nit really is in sleep mode, but the monitor goes into low power, and the\nbooting process stops. If I clear the bios & hit the switch, it says cmos\nsetting bad, cmos/GPNV checksum bad, hit F1 to enter SETUP, F2 to use\ndefault values. I've changed just about everything in SETUP to no avail. If\nI hit F2 and take defaults, it will boot and run okay until I have to reboot\nagain. Then I must go through the same process again. Anyone have any ideas\nabout this? Thanks!
