The Acer Aspire L100 is a desktop computer powered by a special DC adaptor 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 burnt 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.
