RISOLTO IL NOTEBOOK E' RINATO (NON SI RIAVVIA,FUNZIONA DI NUOVO IL RISPARMIO ENERGIA SCREENSAVER TUTTO !!!)
E' un problema che affligge i toshiba satellite a300 risolvibile (modo complicato) sostituendo un componente sotto la cpu il NEC/TOCKIN 0E907....
The first solution is already posted in page 2,
and the 2nd alternative (difficult) solution is to replace the NEC Capacitor.
The 3rd is to delete all system files and hidden files of "intelppm.sys".
(there are 3 of them in Windows system folder, just use the search button to find those files)
The fourth solution is delete the registry entry (goto windows Run > type 'Regedit' ):
Delete this key:
The drawback is the power consumption of CPU will be high and it will consume much battery and power."
Io ho levato la chiave dal regedit (opzione 4) ed č rinato !!!!!
