joan’s PC dead. on connecting power cord, green led on bac of case comes on briefly, then goes off. pressing power button does nothing.
we did have a small 1sec~ power outage Thursday? but i think she used pc after this?
pc is Dell G5 5000
on inserting power cord to power supply, led next to socket on back goes on for ~3 seconds then goes out. attemptig to use the front panel on/off does nothing (dopesn’t come on, blink, in any colour. this is with RAM, SSD, and GPU out; no beep codes either
power supply is not ATX standard; has few power connectors. 500W, only outputs 12VDC
model L500EPM-00 Dell P/N 99TPH
doesn’t use standard colours…. assuming
BRN is +12V
BLK is groud
PURPLE
PURPLE
NOTE!! the following are smaler gauge wires, therefore likely control signals.
BLUE
GREY -maybe
so if GREY is “power good”, perhaps BLUE is the “ON” signal to the power supply; pulling this LOW (to ground) should turn ps on? BUT what is purple?
PURPLE rings continuous to other BRN, so is likely 12VDC too. but sould open PS up to be sure.
allegedly avail from ebay or others:
but not sure if this is the problem….
test GPU:
test RAM:
test
