I reset my surge protector and the computer wont power up. i think i need a new power supply. the power cord is working fine. Please let me know where i can find a power supply for the aspire...


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..

    Hi i have an acer aspire E380 and it doesnt boot up when switched on,it doesnt even beep. noce rare occasions it with work fine but it may take many attempts. what could be the cause many thanks.


    Your problem is either with your power supply or motherboard, but being as it boots somtimes and then dosent, and not even a beep, then the power supply would be the main cause, i sugest taking the power supply out of the computer and taking it to your local pc store, ask them if they could test it for you before you buy a new one. hope this helps.

    How to change the power jack on acer aspire 5000


    This is a big job. It requires taking the unit completely apart. Many small screws and pieces. Also may require soldering the new jack to the board. If you have never done it before suggest bringing it to a repair center.

    Many things can go wrong that can kill the laptop.

    Hope this helps!

    Acer 9100 dc jack broken


    search ebay for a DC Jack for your model. Disassemble your laptop. Desolder the broken DC Jack from the laptop motherboard. Solder the new DC jack onto the motherboard and reassemble laptop. If your not experienced in soldering of disassembling laptops I would recommend you hire someone to do this job. If you wish contact me jason@jrdtech.net

    The laptop turns itself off but doesnt come back on properly. if u touch it in the wrong way it will turn off. sometimes the power comes on but no screen


    the power supply inside check for the AC adopter if not the problem is due to DC jack.if you change is it ll go well.since you are saying there is no display check out the VGA....hook up theexternal VGA port and try .if there is a display then you have to change theVGA.
