M17x R2 "Plugged in, not charging" fix

[Madcat]

Half a year ago I had the "Plugged in, not charging" error on my M17x R2.

After trying the Stealth mode toggle, the A10 bios update and the re-seating of the batter, the problem still persisted.

So, after removing the battery from the M17x R2, I cleaned both the contacts of the battery and the receiving contacts of the motherboard.

I used a very fine grit sandpaper (P1200 for example) to get in between the contacts of the battery (don't need to go wild here, it just needs a surface clean), and afterwards, I cleaned all the "debris" with a piece of paper with rubbing alcohol on it.

Make sure to thoroughly clean the contacts with the rubbing alcohol! You do not want any form of debris to remain in there.

A friend of mine advised me to use a felt pen, but the sandpaper did the trick for me.

Afterwards I just refitted the battery and never had the "Plugged in, not charging" problem again.

Hope this tip will help someone here on this forum.

there is a small memory chip inside a charger, it tells to motherboard (KBC) what chargers it is through that middle pin in charger connector ... if DC-in socket is damaged somehow then it will not recognize the charger and it will not charge a battery because motherboard doesn't know what charger is plugged in .
