Acer Aspire 5742G No power

Hi Guys,

Today we had an all time favorite in the shop. A Acer Aspire 5742G Laptop, with aย no power symptom in the description. The cliente told us that the laptop just died from one moment to the another, and then i wouldn’t charge or turn back on, but when you pressed the on/off button there was a half a second light.

So we took it apart and looked around for any sign of burned or damaged componentes, and eventually we spotted a what looked to be a burnt ceramic capacitor near the U20, this board is a LA-5891P, and its pretty common in these machines. After testing this little guy with our multi-meter it read “Short”, so we turned on you Hot-Air station and swapped him with another.

Wouldn’t you know it? That was the only problem… We powered it back on and “lo and behold” we were in like Flynn.

It’s refreshing to have an “Easy repair” from time to time, and it just makes me remember that sometimes things are just as they seem. In this case, that ceramic capacitor was slightly discolored, and that is what brought my attention, this wasn’t the first time that i nailed it on a first draft, ย and it most certainly won’t be the last.

If it looks to easy to be true, then it probably is… but hey! just give it a try… you might just get lucky.

Thanks for reading.
