Having problems with your Acer Aspire (AST180-US340B) PC Desktop ?

My Aspire M1600 (desktop) might have encountered an overvoltage surge and wont start at all. The lower blue LED on the frontpanel is flashing slowly (1 sec). Where to look /what to do? Looking forward. BR Lars


Answers :

Test the power supply first- to do this you should use a "tester". OR un plug the power cable from motherboard 20/24 pin adapter and might as well unplug the rest of it for the testing purposes. With the 20 pin cable unpluged look for a GREEN wire on it then taking a paper clip TOUCH green wire to any SOLID BLACK wire. If the power supply powers up - fan comes on- its likely a Motherboard failure.

Note: you can (test power) on the power supply with everything plugged in by "shorting" the green wire to black wire for 5sec. if the pc AUTO turns back off after 5sec it is bad motherboard or "maby" CPU/actual processor.

If you can throw some other RAM into the motherboard and try to power on normally.

You might want to RESET the bios - look for a jumper on the motherboard with 3 pins and - while unplugged from wall power - move the jumper to the other 2 pins (should share the center pin from 1st position) leave there for 5sec then move back to origional pins it was on. Then re-connect power and turn on normally.

For the past week, when my Sceptre LCD monitor goes to sleep after inactivity, it won't restart immediately. The blue LED blinks every second or so; eventually, the screen begins to flash the display, and then a few minutes after that, will finally turn on. Sometimes the whole process takes five minutes, sometimes an hour. How can I fix this problem? (I can't find the documentation to say exactly what model this is; if that's important, I can look again.)
