All 4 of the USB ports on my Toshiba Satellite A105 lap top have gone dead. When I plug in a flash drive nothing happens.
Wired mouse operation is very erratic to the point the mouse is useless.
My MP3 player plugs into a USB to connect to the computer and to charge the player's battery. It works on my desk top but not on the lap top.
I tried reinstalling the XP operating system; had no effect.
Based on the fact that it won't charge my MP3 player I'm guessing it's a power supply problem. Is there a a diagnostic I can run to verfiy? Also, is this a complicated repair or can someone who's reasonably handy do it?
Thanks
