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.

My Dell inspiron 13r laptop is emitting a very high pitched noise when it is on. I have tried reinstalling my audio drives but nothing seems to be working... Please help


If it is a relatively quiet, high pitched noise, it may not even be from your speakers. I've experienced a high pitched noise whenever i plug in my AC adapter to my PSP, so there is a chance it might be power related.

The problem might be the power supply charger that plugs into the laptop, unplug the charger and run the laptop on battery power, is the high pitch sound there when you power up? if this solves the problem, it is the power supply charger that is the cause.

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.
