That sounds like a bad PSU. Open the machine and clean if needed.

SOURCE: power tower wont turn on. when you press the power

First thing I would check is the power supply, easiest way to test it is to just swap the power supply with a working one.

That's easier said than done if you're just an average user so unless you've got an extra power supply handy then I would suggest finding a local computer repair shop that provides FREE DIAGNOSTICS, most do these days. Have them check out the system. It's either the power supply or motherboard. HOPEFULLY it's just the power supply though ;)

If the repair shop says it is the power supply I'd sincerely thank them for their time (5 minutes) and then I'd buy a replacement power supply and install myself ($15-25)

Hope this info helps!

The most likely cause is a failing power supply. Unless you have a tester you will need to buy a replacement. Check the specs and order a suitable replacement. (www.newegg.com is my choice)

If any of this goes past your computer knowledge take your computer to an expert to examine first-hand.

How can I tell if my power supply is bad?


Switch the machine off and leave it unplugged from the mains for 5 minutes, while it is unplugged press the power on button a couple of times. (This will make sure all of the logic in the tower is reset, ) Then turn it on again. The only way to test a power supply is with a multimeter or a PSU tester, the second one is easier and cheaper. (about 5 to 10 GBP)

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..

    My new omega washing mashine shows an E2 error code 5 miniutes into the wash how do I fix this?


    Hello,

    Manufactured by omega washing mashine have an electronic controlpanel that must be unlocked in order to set or make changes to your washingcycle.
    E2 indicates a water leak. When a leak occurs, it trips thefloat device by dumping water into the dishwasher's base. The incoming watervalve will be switched off, and the drain pump will turn on until the sump isempty
    However, if an error light is blinking on your dishwasher'scontrol panel, the panel must be reset before you can gain access. Blinkinglights on your washer control panel may signal a mechanical problem that needsto be repaired. If the lights continue to blink after you've reset the controlpanel, contact Sears to service omega washing mashine or considertroubleshooting the appliance yourself carefully.Instructions
    1 Press and hold the "Heated Dry" button onyour omega washing mashine for four seconds to unlock the dishwasher controlpanel.
    2 Press the "Heated Dry," "Normal Wash,""Heated Dry" and "Normal Wash" buttons one after theother, in fairly quick succession.
    3 Wait for the washer to run a short diagnostic test.
    4 Press the "Cancel/Drain" button at the endof the diagnostic test cycle. This should reset the control panel on your omegawashing mashine. Thankfor using fixya.

    Hi,
    If you are referring to the green light on the system tower and is blinking the problem could be the system is in stand by mode.

    Turn off the computer by pressing on the power button on the system tower for 10 seconds.

    Disconnect the black power cord at the back of the system tower and then again press the power button on the tower for 10 seconds. There would be no activity on the tower when you do this.

    Reconnect the power cord and then power on the computer to see if the issue is resolved.
