My son has been given a GVC laptop, model GREEN775. The battery is fully charged but it doesn't appear to want to wake up. When the on/off button is depressed the LCD shows the battery status and Zzz at the opposite end. Any help would be appreciated towards waking this lazy 'puter. Also any info regarding its spec would be appreciated. Please e-mail me at email@example.com with whatever you have. Thanks in advance.
