Red light on my tower and it wont work

Psu no power - replace Psu

The Acer Aspire L100 is a desktop computer powered by a special DC adapter and power cable. The computer's motherboard incorporates a fuse designed to prevent any power surges from damaging the computer. If the fuse burns out due to a power surge or for any other reason, the computer will no longer function. You can check the motherboard fuse for damage yourself, then take it to a trained technician for replacement if needed

Shut down the Acer Aspire L100 and turn the tower around.

Press the "On/Off" button on the front of the tower. If the computer will not boot and the fan does not turn on, the fuse may be burned out.

Unplug the power cord from the rear of the tower

Turn the tower on its side and remove the Phillips-head screws connecting the back panel to the Aspire L100's cabinet.

Pull out the motherboard assembly gently from the back of the cabinet. The internal fuse is located on the motherboard behind the DC power jack, which is to the right of the monitor jack

Let me know if this helped..

sounds like the cpu fan and that would also explane the green then red lights also open the tower access panel but first unplug the unit,wait 30 secounds or so plug the tower back in then look at the fan sitting on the motherboard or main processer see if it turns on and make sure it keeps running they tend to start then if there is a problem they eigther don't turn on at all or turn off a few secounds later Im thinking later would explane the lights

Press and HOLD the ON/OFF button for TEN seconds, until the computer turns itself off.
Then, press the ON/OFF button as per normal, and it should start.

i found the same problem (can't load BioS) but we are not alone as you can see on web about M1640 and M1641 it's very popular defect
I made various test:
cpu (pentiun e2180) pass the test mounted on another PC.
I removed the two ram and replace with other ,result nothing (Pc power on but can't load the BIoS).

Change the MotheBoard

So I have found the answer myself ;o)
I removed the front panel of the computer, behind the panel the wires were labelled, I connected the cables to the connectors that I required and connected them to the MoBo, works like a dream!

if its the red flashing light on the tower, its the hard drive activity light.

when the monitor goes on stand by, does the tower retain power? (green light on and flashing red light sometimes?) Does your keyboard's scroll lock/num lock/caps lock keys and keyboard lights work?

back? dvd.cd drives usually slide out the front.i think ur try to push a door that u have to pull. rating please. get back if not the solution

hi first of all check that nothing is touching the blades then spry some oil in the hinge (WD40..) make sure both ways of the fan are open for good air flow if the SUDDEN accelerations annoys you then connect it soo it will run all the time - take the red and black wires to the red and black wires of the 5v hardiscs good luck
