1. Remove AC, battery and press, hold the power button 20 seconds. Replace battery, AC and retry.
2. Never let a laptop sleep and the battery run out as it may need this sort of reset to recovery.
3. Try the Fn+Fkey combos that enable or switch display modes.
I have a brand new Sony Viao PGC-7141L laptop
Windows Vista Home Premium
3 gigs ram
250 gig hard drive
Last Friday I placed it in hibernation mode and forgot to wake it up until the following Monday afternoon. When I tried to start the machine the power light (green) turned on and the hard drive light (orange and yellow color?) came on for about 5 seconds. I can also hear the cdrom being read as well. I waited but it never woke up. I decided to plug in the AC plug thinking that the battery may have died and allowed it to recharge for 36 hours.
After recharging I attempted to use the reboot steps off of Sony's website and contacted tech support (they gave me the same answer.) After contacting tech support they suggested that I send it in for service!
Does anyone have a way to awaken my machine? I need it for school. Any help will be greatly appreciated.
