Okay so 19 volts getting to the board, no boot, this could be a few things make sure the mobo is securely grounded (some boards are picky) make sure that all the cables (20 pin connector and 4 pin connector if there) are connected all the way.

Lost a power cable?

Like it was walking down the street one day, and the power cable fell out of it's pocket?

Or do you mean came loose?

Or in YOUR estimate, that one power cable coming from the Power Supply, is bad?

The first one I was trying to be funny.
I'm serious about the last two.

http://www.geeks.com/details.asp?invtid=ASL100-UA380A-R

Hmmm, okay let's try this another way,

(Notice I didn't even go to Acer Support. With the info they give the consumer, it isn't worth the trouble. Also tells you a lot about this computer company.........)

http://www.ebay.com/itm/Acer-Aspire-L100-Motherboard-MB-S6909-003-MBS6909003-/120919471509?pt=Motherboards&hash=item1c275cb595

Oh, I see................

http://www.amazon.com/Acer-Power-Aspire-Adapter-Supply/dp/B004PYZSCC

I just got schooled.

Don't believe there are any power wires inside to connect, Christina.
Power is from an external power supply, that plugs into the computer.
(Like a laptop)

The only wires in my estimate, is;
A) The small audio wire from the optical drive (CD/DVD drive) to the motherboard, (Close to the Blue VGA port)

B) The Front Panel wires,

C) USB Front Panel port wires to motherboard

D) Media Card Reader wires to motherboard

E) Harddrive and optical drive data cables to motherboard. (One each)

(The front of your computer is the Front Panel)

Computer not coming on?
See if the external power supply is good.

Voltage coming out is supposed to be 19 Volts DC.

The plug end on the external power supply;

The center hole is the Positive ( + ) connection.
The cylindrical metal shell on the outside, is the Negative ( - ) connection.

Multimeter positive ( Red) probe lead goes to center hole.
Negative ( Black ) probe lead touches outside cylindrical metal shell.

Multimeter positive (Red) probe lead, plugs into red hole on multimeter, marked DCV.
Negative (Black) probe lead only has one hole (Black), to plug into.

Function knob is set to DC Voltage. DCV.
If just a symbol, the symbol is a dotted line over a solid line.
If more than one scale, set it to the 0-50 Volt scale.
(0 to 50 Volts ]

An economical multimeter is about $5 to $12.
Auto parts stores have them. (Although probably more expensive)
I have seen them on checkout aisle racks, at major discount stores.

While checking the AC adapter, have an assistant gently wiggle the cable, from the AC adapter TO laptop.
See if the reading on the multimeter fluctuates. If so you have a broken wire in that cable.

Have the assistant also gently wiggle the power cord.

Or take down to nearest 'Mom and Pop' computer shop, (Small store), and have the resident tech check it for a few bucks

Could also be the Power On switch.
This is located inside the plastic assembly, of the power on button.
They go bad, and do not leave a forwarding address ;)

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 aspire L100 will not boot. When on button pressed blue light comes on and then goes off straight away and fan starts Ok but nothing else


    You may need a new power supply....also check your internal fans to make sure they are spinning. Make sure memory is seated properly. Motherboard may also be in question. Try unplugging letting it sit for a few then plugging back in.

    The acer l100 does not power on at all no lights or fan running


    If the computer is not starting then and the power supply is ok then you need to try a different charger. If the problem still exist this may a sign that the motherboard is dead and need to be replace, because when a motherboard is dead it the computer will not receive any power.
    Thank you

    Hello again....i've just discovered within the setup and PC health status that there seems to be a problem with the 12v supply. There are 3 different Voltage meters: 1) 12V 2) 5V 3) 3.3V Alongside these is...


    Having never repaired, or seen an Acer Aspire L100 desktop, I went to Acer Support, and reviews on the internet. (I do repair computers, however, not just Googling info off of the internet here)

    Seems the Acer Aspire L100, uses an external power brick for a power supply. Also looks like they're harder to find than hen's teeth!

    It does seem judging by your findings, that your problem is the power supply.
    A computer power supply put's out three main voltages, (Such as you have seen)
    A.3.3 Volts
    B.5 Volts
    C.12 Volts

    You obviously have a weak 12 volt power rail.
    At this point I would take the power brick to a repair shop. I'll bet it's bad Electrolytic Capacitors, but this is just IMHO.

    Also read where there are problems with overheating issues. Most post that the front door should be kept open, when using the computer. Better make sure the inside of the computer is clean, as well.

    (Computer off, and unplugged from power. Use a can or two, of compressed air for computers.
    Pay special attention to the heatsink under the processor fan, and the processor fan.
    Do NOT keep constant air pressure on the fan. It is only designed to spin so fast. Spinning it faster than it was designed for, can lead to premature failure of the fan's bearings! {If you hear the fan go 'Zing' get the air pressure away from it!}

    BEFORE you reach inside the computer, unplug the power from it. TOUCH the metal frame of the computer case, to relieve your body of static electricity. Static will fry out those delicate computer hardware components. You may not see it, or feel it!
    Zap! There goes your computer!

    Try to gently move the fan blades by tipping them. Looseness in this area means the fan bearings are shot. Replace fan)
