Question about E-Machines eMachines Desktop PC
Left D2880 off, with powerstrip off, while on vacation for one week.
came back, no power, but green light on motherboard. switched outlets, cable and power source-no power. observed charred component on motherboard, took power source in to comp-usa, tested good. installed new motherboard-no power. have tested and swapped power switch, checked and rechecked all connections and swapped out processor with one that came from a running unit. still only get green light on mother board. tried to power up without dvd and another good hard drive, green light on mother board. could power source still be suspect
even though it was tested? noticed the guy only tested the lead to the
cd and hard drive, not the P8 lead to the mother board.
Probably yes, the poiwer-source may be delivering "dirty" power (happens also when using a back-up generator, as in the power in the building goes out, or when used in an old RV, and the back-up kicks in) <--- is a safety feature to protect the CPU. Try also a different powerstrip, or head off to the neighbors and try their plug before swapping out the power supply.
In the end, you may wish purchase an inexpensive clone-tower, swap out the HD and processor (if you are spending too much time and money trying to band-aid the old one)
Hope this helps!
