Laptop boots only if CMOS battery is removed, then replaced
this Dell Latitude E6400, win7pro, began to show a problem of spontaneous rebooting when the lid repositioned during operation, several days later it finally failed to boot. The power button 'l e d' stopped lighting and the laptop was unresponsive. I thought the power button had failed but I tried removing the cmos battery and replugging it and the laptop booted. It will warm boot but will only cold boot if the cmos is unplugged and replugged. Hopefully this is not a motherboard failure...any ideas about repair???
