Have been given a Toshiba Protege R400 Mod No:PPR40A-01000L to look at for a friend who is very ill and the machine just will not switch on.
Have tested the adaptor and battery voltage and there is plenty.
Now I don't have much experience with laptops as such and so cannot rule the PSU as the culprit.
When plugged in the blue power light is on and the small yellow battery indicator flickers at random speeds - but quite fast.
I have Googled it but cannot come up with a definitive answer.
Now I have the maintenance manual for it and I can probably get the LCD mask off to look at the power witch itself. But before I do I would like some opinions on the most likely cause and would prefer to avoid this if at all possible.
So any Toshiba / laptop folks out there any suggestions please.
