My computer does not start up looks like in satnd by mode


Most All-in-One Personal Computers (PCs) are based on internal laptop/notebook component technology.

The first item to test is the Alternating Current (AC)/ Direct Current (DC) Power Adapter to see if there is:

damage or a fault in the cabling;

damage or a fault in the transformer box;

a fault, damage or a loose connection in the AC/DC Adapter Jack point via which the AC/DC Adapter plugs into the PC.

If no AC/DC Adapter-related fault is evident or any such fault is definitively resolved (such as by testing a definitively functional replacement AC/DC Adapter), then his sounds like either a Loose AC/DC Power Jack detached from or short-circuiting its Motherboard Solder Points, a Power Management problem on the Power Management Tracks, Electrolytic Capacitors or Power Management Contoller Integrated Circuit (IC)/Chip on the Motherboard or a Graphics Chip or Graphics Card damaged surface or Motherboard Solder Point Contact fault.

Any of the 3 internal faults described above would require specialist internal diagnostics, repair and testing by a technician with specialist laptop repair experience and specialist Infra Red Workstation, BGA Reballing StationMicro-Soldering, Oscilloscope, and Multi-Metering equipment.

DC Jack repairs are likely to be moderately expensive. Power Management or Graphics repairs are likely to be more expensive still, but if conducted by a professional, all three repairs should resolve the problem. A competent repair technician should be able to repair these faults and offer a minimum 3 month warranty on a reoccurrence of the same fault.

So, on the symptoms described in the question, yes. Unless it is just an AC/DC Adapter fault, this will probably prove to be a serious, non-DIY repair problem, I'm afraid.

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 gateway laptop note book, will not power up, I have checked the cord, battery etc. Went to turn it on one day and no power? someone mentioned that it over heated?


    First of all, take the battery off and try to turn it on with the ac adapter (power cord) connected. If it comes up without the battery then it's your battery.

    If it doesn't turn on without the battery and with just the ac adapter, try a different ac adapter. You can find one to try at your local pc shop or electronics store. If it comes up with another ac adapter then all you need to do is purchase an ac adapter at the store or order one online (cheaper).

    If it still doesn't come on then it's either your dc jack or your motherboard. Normally if it's just the dc jack it will turn on or attempt to turn on when you wiggle the connecter in the ac adapter connection. If it's your dc jack it's relatively inexpensive to purchase online. The problem comes with having to take apart the laptop, desoldering the old and soldering the new dc jack, and putting the computer back together.

    Good luck and let me know if you have any other questions.

    Laptop wont come on


    1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
    2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
    3. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re-soldered. A broken one will need to be replaced.
    4. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
    5. The power button could be bad.
    6. The motherboard could be defective & needs to be replaced
