Acer Travelmate 4601WLMi battery charging cct

[Gazza]

Hello,

I have an Acer 4601WLMi laptop and I fear that the internal battery
charger circuit has died. My screen keeps blipping between full
brightness and reduced brightness (as for battery power) and the
charge LED on the front of the unit does not always light. Also
needless to say the battery is not lasting long....

Can anyone please give me some pointers of how to perform a repair and
or what and where to look as its driving me mad. Also any good places
recommended for sending for repair (UK)?

Many thanks in advance.

Gary

One thing you can try is to clean the contacts on both the battery and
its mating pins in the computer (if you can get to them). It sounds
like intermittent contact somewhere.

You might just get lucky.....

Hi!

It would be worthwhile to examine the power brick or the connector for it on
the computer to see if either one has failed. It sounds like you're losing
power input to the computer and it switches over to the battery as a result.
If it were to happen enough, this could make charging the battery a very
lengthy proposition. You might get lucky and find a bad line cord (most are
detachable and therefore easily/cheaply replaced), frayed wire on the output
side of the "brick" or a dirty connector.
