High pitch noise coming from laptop

Hi,
I have a laptop computer and it makes a high pitch noise constantly. It drives me crazy and I can only stay on the computer for short periods of time. It is not loud, but auditable.

Likely it is the system cooling fan or processor cooling fan so check to see if you would like to put it back under a manufacturer warranty if possible or whether you have the skill to review, follow, and carefully open up and inspect and clean and reassemble your notebook PC. What price is it worth to you to fix this problem - the downtown computer retailer that sells CDs and PCs and appliances will charge you to fix it. Again, most likely it is a simple small fan inside the PC. It could just have lint, dust, fuzz in it and after a clean out could work quietly again. The CPU cooling fins or cooling fan blades after cleaning will allow the CPU or system to operate more coolly, and then the fan RPM could drop a bit and the notebook PC whining sound may decrease. Oh, finally, putting the notebook PC on a grate or grill or a notebook cooling ventilation platform could alleviate the problem if it is just lint or dust.

Annoying noise


The noise is probably coming from the hard drive, remove it and see if that will solve the problem. That high pitched sound means the hardware is on it's way out.

My laptop makes a high pitched noise


The high pitched noise you hear is most likely caused by the CPU cooling fan on your laptop. If you suspect that this high pitched sound is caused by the fan going out, you can spray your laptop with compressed air to get the dust off of the fan.
This solution will make your laptop work at a cooler temperature, and reduce the noise.

If the problem persists, seek a certified laptop repair specialist.

Dependant on a high pitch scream this could be a number of problems, memory modules loose or faulty?? Would need more info about the type of sound..

Hi grade laptop makes high pitched noise and the screen is blank


High pitch noise usually means the inverter board that drives the lamp behind the LCD display. If the rest of the laptop appears to work, for example, hard drive light blinking while booting, try hooking up an external monitor and hit whatever function key that switches you to the external monitor. If everything works, you may want to replace the inverter board yourself. It is not horribly hard if you are very careful. But it is not exactly a walk in the park kind of work.

If the rest of the laptop does not appear to work, the DC-DC step down power circuit is probably shot, which will also make a high pitch noise. In this case, you will have to replace the motherboard. Replacing a motherboard is a major pain in the behind. In most case, it is not worth the trouble if you have an older model.
