Toshiba Laptop doesn't recognise when running on AC power

By alan.vincent2 ·
Hi I have a Satellite Pro that works fine but doesn't recognise when running on AC Power. Works ok on both battery and AC, removed battery and run on battery alone with no problems. I have tried a replacement battery to no avail. Problem being is that it won't run a couple of lage programs as a box pops up 'this progam requires you to be running on AC power' so requires to be on AC power to continue, even though it is. I have tried all setting in the Power Consul and have downloaded all the BIOS and relevant updates for the specific model from Toshiba but the problem still persists. Any help would be much appreciated as I have run out of ideas other than it could be the main power board inside!

Does the battery appear to be charging when

the AC adaptor is connected? Typically there is some sort of light.

The main question is whether the AC adaptor is:

a) working at all (e.g. dead)
b) outputting reduced voltage (check with a multimeter)

Perhaps the power supply connection on laptop or power supply is damaged (common problem).

Will it run on AC alone? (no battery)

My first guess would be that the power supply connector on the system board of the laptop is damaged...does the symptom change with some gentle wiggling of the connector?

Have you got another power supply to try?

Is this the original Toshiba-brand power supply for the laptop?

Some Dell laptops are very picky and a 'generic' off-brand power supply will not provide sufficient current....

Well it could be the M'Board but it just as easily could be

The Mains Adapter here. They can start running at reduced Current and this could be the problem here.

About the only test available is to use a Known Good Mains Adapter and see if this cures the issue.

Is there any difference in the brightness of the Monitor when you plug in the Mains Adapter?
