Having problems with your Dell OptiPlex GX620 PC Desktop ?
Will not power up. When I plug in the power cord, a small orange light comes on - on the mother board. Other than that, nothing happens when I cycle the power switch. I replaced the power supply, but still the same result.
Try re-setting the BIOS by using the clear CMOS jumper on the motherboard. If that does not work then remove the memory dimms, cd-rom drive, hard drive, floppy drive and any PCI components. After that try the computer and see if you at least get a post-up screen. If you do then re-connect each component until the post up screen stops again and that is your problem component. If not then your motherboard is bad.
Bios battery is dead,looks like a nickle.

Have a Dell XPS 200. Computer was on overnight when our power went out and then came back on. It was plugged into a power strip with surge protector. Now it will not turn on, no power, no lights, no fan comes on. It's just dead. Unplugged it, plugged directly into wall, turned the switch on the back of & on. NOTHING. What could cause this? Power supply, mobo? Could the bios battery cause this? Thanks!
Most probably, the fuse in the power supply has been burnt out when the power came back. Surge protectors only protect against voltage surges, not against rise in electric current (Amperes). The fuse inside your computer's power supply protects again ... PC Desktops
