My Dell D505 started acting up recently. When I would boot sometimes it would beep 4 or 5 times (short beeps no long pauses) and then go to Windows no problems. Sometimes it would beep 2 times and write "Strike the F1 key to continue, F2 to run the setup utility". Nothing else, no other diagnostics. Hitting either F1 or F2 would not work, and I had to power down and power up again, then it would work normally. Starting from today it beeps 2 times, writes "Strike the F1 key to continue, F2 to run the setup utility" and no amount of power downs helps. F1 and F2 don't work either, however I discovered by accident that hitting Fn+F1 actually gets me to the first page of the setup, while hitting Fn+F3 gets me to the 7th page :? In setup I've disabled internal modem and all the other peripherals, removed everything but the HDD and CDROM from the boot sequence, changed POST to thorough mode, but nothing helps. I've tried reseating RAM, I've tried booting without the HDD (It would then at least write that primary disk was not found), disassembling the laptop and plugging/unplugging the keyboard+touchpad connectors. Nothing. Any ideas? Thanks!
