I have a Dell Latitude D630. When the laptop is switched on it emits a high pitched scream and will not boot. I disabled microphone in BIOS and machine boots fine. Re-enabled microphone and same probl


It sounds like a driver problem, normally the microphone is off on-boot-up. It should only be opened by a program wanting to use it.

Have you tried turning it off in the operating system, rather than the BIOS?

Download the correct drive here.

High pitched noise red light blinking


A high pitch noise comes normally from blown capacitors from the motherboard or the power supply. But mostly high pitch noise comes from power supplies.

You could have to open up the power supply to see them.

Verify if it is the case and replace the faulty part.

Machine emits continuous high pitched bleep and power light flashes blue/red


If working OK, probably means that the temperature alarm goes off because is getting hot the PC. I suggest to check why is that happening. All fans working OK? is the CMOS temperature alarm set too low? check your motherboard instructions booklet- It will tell you what the beeps mean probably in the last pages. Good luck
