At boot up, after the POST, each time the HDD led blinks, the laptop produces a loud "beep", and refuses to boot, as if this phenomenon prevented the HDD to be read.
If I press the power button, it stops beeping. When I release it, it starts beeping again.
If I press F8 at the beginning and then ask for a normal boot, It boots normally. Anyway, in windows, I have some strange activity, like I would continually pressing Alt+Tab. If I press Esc, it stops immediately and then all seems to work fine.
Try power cycling the laptop by taking the battery out and pressing the power button 10 times. On the 10th time, hold it down for 10 seconds. Put the battery back in and attempt to boot the laptop.
If that doesn't work, listen for a cooling fan when you attempt to boot the laptop. If you don't hear the fan, it's likely that the motherboard is malfunctioning somewhere.
Do you hear any beep codes when you try to turn it on? Here is a list of beep codes for reference:
No Beeps: Short, No power, Bad CPU/MB, Loose Peripherals One Beep: Everything is normal and Computer POSTed fine Two Beeps: POST/CMOS Error One Long Beep, One Short Beep: Motherboard Problem One Long Beep, Two Short Beeps: Video Problem One Long Beep, Three Short Beeps: Video Problem Three Long Beeps: Keyboard Error Repeated Long Beeps: Memory Error Continuous Hi-Lo Beeps: CPU Overheating
Hope this helps! Good luck!
