Machine Starts Only after CMOS battery removed and replaced
Posted on 2013-06-03
I have a new Lenovo machine which we tried to use an additional video card in. After trying we realised that the power requirements of the card were too high for the power supply. When we reinstalled the original card it stopped powering up.
An identical working power supply was used to check it did not start. I have now discovered that it powers on when the CMOS battery is removed, it may continue to power on once or twice after the battery is put back in but then the process has to be repeated all over again.
Any ideas on the reason for this.
