Question about Acer Aspire L100 PC Desktop
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
oh and let me know how you made out later
