Find a shop that lets you try another adapter and a replacement battery.
I have a problem with a Toshiba Satellite L150-18D laptop which won't power on.
When I press the 'on' button, the light with 'power' symbol comes on for about half-a-second, then goes out. The is no indication anything is happened (fan doesn't start up - no sounds or anything). There is no difference if the AC is connected or not connected. The 'charging' light does not come on at all.
The battery may have ran out - am not sure. My wife fell asleep so isn't sure but it does normally hibernate when it thinks it has 5% of power left.
I have swapped the battery with an older one (this was replaced about 6 months ago and I have never got round to recyclcing the old one). Now, the old one wasn't working properly and by now will likely be completely drained. When this battery was in, it still didn't start and the charging light still didn't light but this time the power light didn't come on either when I pressed the button.
I've tried doing a system reset but no joy.
I don't have any other batteries or AC packs to try it with and there is nothing visibly wrong (like a black 'bang' mark on the plug).
Any ideas anyone? The obvious things are the AC pack or the battery (the old battery may be a red herring) but I don't have anything spare to test with or know anyone else with a similar AC pack (the other Toshiba one had a slightly different sized connector so couldn't test it).
I don't want to keep buying new parts to try for it if this is indicative of another problem. I don't have a vault meter to test the AC pack and am less keen to try the 'licking whilst plugged in' method
Cheers for any help.
