CMOS Wake On Alarm Question
I have a Acer Verition M460 [AMI BIOS R01-C3] with WindowsXP SP3.
I had the CMOS set to wake and boot every morning. Worked fine for several years. Then intermittent, now not at all. In the morning the power light is on and the NIC light is sometimes on. Screen has no info and the PC has stopped short of actually booting [so Event Viewer has no info]. I simply hold the power button 3 seconds and repower up. Always successful. Time/date is accurate but I changed the CMOS battery and re-enabled the RTC alarm. No joy. Obviously not a major issue but I am curious, any idea why this is happening? Thank you. |

CMOS Wake On Alarm Question
In case anyone has a similar problem, this was answered in a different
thread. Cap on motherboard located near CMOS showing bulge + running very hot. Likely suspect.
