Power supply problem

Hi, I'm having the same problem with one of mine M1 Active 620. Please have you found out characteristics of D5 Zener diode, voltage?

I went through this same scenario.Motherboard,power supply, ram, Couldn't figure it out.Turns out it was the Power button itself.Put all the components in a new case an viola everything works

try to buy new power supply

These use a standard Power Supply that you can get from almost any computer shop

Better to get one slight higher rated so maybe a 350 or 400w PSU

you can replace these yourself as the connections are pretty easy to follow and only four screws around the supply hold it in

It is a common e-machine issu so long as it has not taken out anything on the motherboard you should be fine.
I have seen the emachines pwer supply take out the main board on occasion although it is quite rare

IS THAT A Relic CRT monitors/?? wow.
NOW THE FULL STORY. (GOT TIME NOW, IM IN MEX,GULF ON A BOAT,WITH SLOW WIFI OR NEAR DEAD.)

the PSU is dead if the power button acts dead
no fans right ? no sounds, the 2 or 3 fans do not spin and blow
1: bad PSU
2: or objects plugged into the mobo are shorted,
3: mobo dead (Motherboard)

do the jump test?

you either have a bad proccesor, or memory, one other thing come to mind is that the pwoer supply may need to be cleaned out use a hair drier and point it at the power supply open the case and do the same for the whole inside pluse the insde holes of the pwer suppply

there are 4 screws on the back of your computer that will release the powersupply at that point you should be able to just slide it out keep mind were you unplug things

The green blinking light can mean there is a problem with the power supply.

Try unplugging the computer from the wall, and turning on the pc on switch.

After a few minutes, try plugging it back in.

If that does not start things up, you may have a bad power supply.

If the power supply is bad, these models take standard power supplies. You should get an ATX 350Watt or higher power supply.

They are easy to replace, unplug the power from the wall, disconnect all the cables inside the computer. Unscrew the four phillips screws outside the back of the computer where the power supply is attached to the case.

Remove and replace.

If you don't feel comfortable with this, a good local computer shop can help you out.

Are any fans running? If not take the power supply to a reputable computer repair person. They can test it while you wait. If the power supply is good or the fans are working then I would remove that new RAM. My guess is the power supply is bad.

Good luck
