Been working at computer shop for decades and knows how to fix the most common PC problems, however this is one rare case I couldn't solve with the basic troubleshooting (cleaning, clr cmos, replace with new cr2032 spare, breassembling parts, PSU swap, detached RAM and HDD). I'm still figuring...
Guys,
I have a Sony VGN-FZ21E the laptop shows no display when turned on and give one long beep and then two short beeps. I've tried connecting a external display but this also shows no picture.
I've changed the RAM and the HHD but the beep still continue, with no display showing.
How do...
