I have a computer that a power supply died. I replaced with the same model, Same amps and watts all the same. The Green light on the mobo comes on, but if i hit the power button nothing. I tested the PSU, works fine. Tested the CPU fan works. Tested the ram, and its fine. I just cant get the thing to power up.

My question is, will a bios battery stop a computer from turning on? i thought if the battery was dead, it would just post funny, but would atlest post.

M y experience of this is yes they will post. Also depends on if the power is turned off between actualy turning the Pc on and off as to if it boots normaly or as you would say funny.

The computer will post, but it will not boot into Windows... You will likely get a series of beeps.

WAaaYY back when i was in School, my A+ instructor disassembled a machine and placed a piece of tape behind the battery and made us build/install as an assignment. This was a pretty good trick.. At the time.

The tape (same as dead or missing battery) caused the machine to fail post. But it did in fact get the beeps.

The computer will still boot without CMOS battery, but you will not be able to save changes in CMOS. The Green light on mobo is probably the power stand by LED. Take a closer look to your mobo for signs of damage components.

now when you installed the new psu, did you make sure to plug in the 4/8 pin cpu power connector?

I think such a problem, the battery should be incompatible with your computer, then your computer or a problem with the internal circuitry.
