Changing out electrolytics on my Acer Aspire L100

It seems my Acer has the same problems with PEC 15, 16, 19

I work in IT, but have never done anything like this. Where can I buy more electrolytics and any advice on changing them out myself? I follow instruction well and have a steady hand. Thanks!

Sorry for not replying myself but I didn’t see your request.

Everything bunnydawg has said is excellent but I would recommend using a pub cleaning solution before you replace the part. Just apply a small amount to a cotton bud and swab the area around the location of the removed cap then let it dry thoroughly before replacing.

When an electrolytic cap vents the residue can be corrosive and unless removed can cause problems further on down the line if you don’t clean it up. Cleaning the area will also make it much easier to get a clean joint when you do replace the caps.

Best of luck

And good eyesite i hope... those boards are soldered by machine in a factory controlled by a computer (of course).
Be that as it may... determine the values of the capacitors. it's written on the side of the case. Not one side has a strip. in other words negative and positive side. ensure you get them in the same way they came out.
Finding the parts depends on where you live. i would suggest seeing if you can find a donour motherboard that you can remove them from. inspect the part first... if it is rounded on the top it's not what you want.

next is desoldering the part. don't try using a 100 watt soldering iron as you will do serious damage. mount the board on it's side with the parts closest to you that you want to desolder... a solder wick or solder ****** is your best bet as it makes for a cleaner job.
determine which two solder points hold in the part. heat them and pull (gently) up on the part. replace the capacitor making sure the orientation is proper and resolder it. careful not to heat it up to much. inspect the solder job to ensure you did not create any solder bridges to other components on the board.

do one at a time so you don't lose track of what you are doing and the orientation of the parts.

I applaud you for attempting this as i see too many things thrown out nowadays that can be repaired.

I repaired an lcd monitor with a $2.00 part and it works great.

back to the board. finish all the parts.... inspect it carefully again for solder bridges. reassemble it ... power it up ... hold your breath and watch for smoke.... if you do the job carefully you will enjoy the results.

Please rate this solution ... thanks

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 acer aspire l100 keeps shutting off. it sometimes will stay on for like two minutes but most of the time it shuts down after like 30 seconds. it works fine in safe mode. most of the time it shuts off...


    this seems like a software issue . if you can not run your system but ift works fine in safe mode try to run a system restore from factory disks and see where that gets 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)

    Could be.


    Ok, they're the kiddies to replace, are they all the same manufacturer? all 1000uf 6v3's?

    What happens is the electrolyte breaks down and produces hydrogen gas, sometimes they can literaly explode but more often than not they'll either blow out the top or the rubber plug on the bottom and just leak the electrolyte on the PCB.

    The electrolyte is corrosive so best to snip the caps out ASAP and clean the board up with a good PCB cleaning solvent before you attempt to replace.

    Sorry if your aware of this, dont mean to teach you to **** eggs ;)

    Good luck

    Over Heating Problem In Acer Aspire L100


    There are two solutions to this problem. First set the fan in the PC Bios to rub at full speed all the time. This was too noisy for me.

    Second, If you are running Windows Vista, you can adjust the Maximum Porcessor Utilization. From the Windows Control Panel select the Power Options icon. Then select "Change plan settings" for which ever power plan the PC is set to use. Then select "Change advanced power settings". Expand the "Processor power managment" by clicking on the "+" symbol. Finally click on the "+" for "Maximum processor state". I would try changing this setting to "90 %". This worked fine on my ACER L100 and it no longer overheats.
