I have a kayak xu800 which has been fine then it suddenly died during use and since then it won't boot up.
First screen on power up OK and it seems to check memory OK. Quickly flashes on while hp startup screen then asks for BIOS password. On entering BIOS password it then beeps 3 times (short) and displays error messages: mouse error , battery may need charging error. It then continues but displays "all devices checked and no OS found" message. I cannot enter setup by pressing F2. I cannot boot from a DOS disc either. I have tried changing the battery to no effect. 3 beeps I believe is a memory error. How can I troubleshoot to find what is wrong and how can I repair?
800 MHz processor, Windows XP, 256 RAM, 8G SCSI HDD.
