Hi all, looking for some help. Board is completely clean, as is the rest of the machine, battery is healthy and charges fine on other machine. The machine is completely dead however did power up yesterday and reported an 3 amber 1 white led sequence which is dying cmos battery. Got into bios, charger detected, main battery charging etc. all looked fine. Powered down, Put another cmos battery in from another machine and it's dead again, no power.
Ordered a brand new CMOS battery to see if that helps but not holding my breath. Have done the whole disconnect battery and CMOs battery, press power button to drain all current, plug back in etc… to no avail… Any suggestions about what to look out for on these? Some dodgy capacitor dragging current down? Re flash bios chip? I think there are two on this model… Nothing gets hot on board as there is no power… using genuine dell charger… thank you!
