Heat makes it evaporate quicker when put on shorted parts that are very hot. Use isopropyl alcohol to locate overheating components.Mostly the 2 primary ones after the charging port, they are very encline to shorts due to their constant solicitations. There are around a dozen, a lot of computers breakdowns come from a short circuit in a transistor.

These components are the power supplies of each part of the board, if one power rail is down then it can prevent the laptop from working. Locate all the coils on the board and check them for continuity to the ground.Test it with a multimeter to see if you get the +Vin (DC +19.5v) at its pins. Here are the top 5 things I always do to troubleshoot your faulty MB: They can also just check your acer Packard Bell EasyNote TE and tell you what part is causing the problem, then it will be up to you to replace it if you prefer doing it yourself (a piece of advice when soldering, always use flux or rosin).

Does your laptop have any issue with the disply, or the power? Start with the basics by measuring the voltage at all the measuring points showed in the repair guide, and come back with all the measures so we can help you fix your acer Packard Bell EasyNote TE.
