Hi

I am new to all this, looked at a lot of forums before to help me out with problems but never posted my own... Here is goes

I have a Sony Vaio laptop VGN-NS20S and am having the following problem.

The laptop boots only when it is plugged into AC and the battery is NOT inserted. If the battery is inserted, despite being on Ac, it will not boot and the power indicator just goes solid green. that is all. Then I cannot shut it down unless I remove the Ac and battery, holding the power button does nothing. I have an identical laptop and the battery works just fine in it so I know it is not the battery but perhaps the pins connecting it or the motherboard.

A bit of history:

I bought it as not working and it had liquid damage for its screen.. after taking out the screen I figured I may aswell see if it boots and it did, just once though. I took it apart and gave the motherboard a good wash and clean as directed by a forum on this site. Put it all back together and walla! It powered up, all the ram is working etc just wont run on a battery!

The specs are:

Thanks everyone! :smile:

Hi is the battery a good known working one

Hi. Thanks for the reply.

Yes the battery is official. I have tried one that I know works in other vaio's.

I tried booting it with just battery but nothing. Then when I try with ac and battery the light for power and battery charging lit up and the screen came on. But would not boot Then I removed ac and screen stayed on so was running on power but would not boot... Just a blank screen came up...??

A bit odd this one.

Also it will boot properly without battery and just on ac... So with the battery not installed... Only way it boots...
