My acer aspire 4935 laptop is not charging when plugged in & power button flushes along with charging LED near touchpad.Sometimes The horizontal led that lights when plugged in disappears...
First, you need to make sure your power adapter is providing enough
power to both run the laptop & charge the battery. A very good way
to do this is to compare your laptop voltage & ampere requirements
(written on a sticker on the bottom of the laptop) with the voltage
& ampere ratings of the power adapter. Voltages should be the same,
or the power adapter's voltage about up to 0.5 volts more than the
laptop's voltage rating. Amperage of the power adapter should be at
least equal to or greater than the laptop's rating. It should never be
less than the laptop's rating, or else the power adapter will be
providing insufficient amperes to charge the battery. Of course, the
power adapter's nominal amperage might be ok, but it degraded on usage.
You can verify this by testing using a good or new power adapter.
the battery did not charge using the new power adapter, take the battery
off the laptop, & using a dry tooth brush, scrub in between the
fins of the battery connector on the motherboard & on the battery it
self, then put the battery back into the laptop & try again.
this still did not resolve the problem, then the battery itself could be
bad. Try it on another laptop, or try a good or new battery in your
If this did not work, there might be a possibility that the
charging circuitry on the laptop's motherboard is defective & needs
servicing. In order to do this, the laptop needs to be disassembled
& the motherboard checked for defective/burned out components in the
area near the DC jack. Any defective/burned out components found should
be replaced, or you might need to replace the laptop's motherboard
