Re: Toshiba Satellite L300 Power Problem
Probably a Maxim or TI battery management IC acting up. If it charges, the charging circuit is fine and running off battery means the rest of the laptop is not shorted. The battery management IC controls the logic of switching between battery and AC. Look around the battery connector and see if you can find a small (~ .5") square IC labeled Maxim or TI.

Re: Toshiba Satellite L300 Power Problem
Did you remove those to see if they were in fact bad? They look like they've been removed. I've never seen those bad - usually its one of the neighboring mosfets or a shorted cap. If one (or more) of those are bad, they will usually give false reading on other components. The only way to tell for sure is to lift one side of the component and test it that way.

Re: Toshiba Satellite L300 Power Problem
20M on the resistors is in fact 20milliohm... that is likely short
for the A300:try to make short on the backup battery, for about 2-3 seconds, without power or battery on it, then attach the power plug, it should start.Last edited by mihaicozac; 03-14-2011, 09:23 AM.

No Maxim or TI IC on my board. Can u please give the location of the IC. Thanks...

Re: Toshiba Satellite L300 Power Problem
When resistor go bad, they raise the resistance, not the opposite.
