So... I admit I messed around with XP/7, but it should at least be able to boot into the bios? But it won't??? I have been through a lot of scenarios, but never ever one like this. What I have tested: Unplugged the battery, power supply etc. and started, but no hopes... Inserted the Windows 7 Home Premium disc I got with the laptop Pressed F12 won't bring up the boot menu, neither does Delete bring up the bios Unplugged the harddrives, no change... I'm lost... I purchased this laptop in September of 2011, but now, after 3 years, it seems like it's time to scrap this old-timer... I REALLY don't want to buy a new one (fear of Windows 8/8.1). Desperate for help from any computer geek GREATLY appreciated!
