Laptop fix.
Had trouble with a laptop recently.
After it booted up it woud immediatly close down. Tried us usual fixes to no avail. Called PC world techguys, (I had a service agreement) and they solved the prob. Hear 'tis.
Remove battery.
Remove mains supply.
Hold start key for 30 secs.
Plug in mains and boot up.
Plug in battery.
All now OK.
Anyone know what was wrong? They said something about static.
Hope this helps someone.
