When I plug in the power supply to my laptop the amber battery light flashes like mad as. The AC power also flashes green like mad.
I bought a replacement battery and that worked fine untill it ran out of juice. As soon as plugged in the charger the lights went crazy.
Does anyone have a clue as to what causes this and how to fix it?
The original battery and charger worked for 3 years with no problem.
I tested the charger and the output was 19V as required by the manufacturer.
I then removed the battery and plugged in the charger and the amber battery light still kept flashing as well as the green AC power light.
I hope this additional info gives you more ideas as to my problem and possible solution.
If the laptop doesn't boot without the battery then looks like you have a power problem in the laptop (as indicated by the flashing lights). The easiest thing for me would be to look into replacing the mainboard.
I took it to Toshiba repair shop and low and behold it was the charger that was no good. So $60.00 later all is well. I appricate your efforts.
I asked how much it would cost to replace motherboard and they said about $300-$400.
