computer making high pitched squealing noise

So I created a new 'power management profile' within the Power Manager applet and set Deep Sleep to off, then saved it.Īfter activating my new profile, the noise immediately went away! Thank goodness for that, because I had to get rid of the noise one way or another before it drove me nuts. These types of controls are nothing new, but in there was the answer to my squealing problem.Īs part of Power Manager, there's a setting called 'Deep Sleep' which is some kind of CPU power management function.

You can slow down the CPU, dull the screen and switch off optical drives if you're running on battery power, and when you're on AC you can disable all that and let it run at full tilt. Since it's a high performance machine designed for development or graphics editing and therefore has heavy battery usage by default, it gives you fine grained control over the balance between performance and power. There's a very comprehensive suite of Lenovo settings which are preinstalled on the machine, and in particular there's an application called Power Manager. But fortunately, unlike many others who had the same problem, the answer proved to be achievable without making any support phone calls or having any parts replaced. I thought I could live with it but when you're sitting next to it for 7-8 hours a day and the sound is drilling into your mind, it becomes quite annoying. However, I had an issue with the laptop where it would make a constant high pitched squealing noise, almost so high pitched that only dogs would hear it, but unfortunately not quite. It's very well put together and feels like it will last for a long time, especially with the hard disk shock detection technology which turns off your hard drive if the chassis detects that the machine is dropped onto the ground There's an Intel Core i7 CPU running at 1.73 GHz, 3GB RAM and a nice 15.6' LED Screen. I recently got a Lenovo ThinkPad W510 laptop, which is a bit of a beast ( PC Advisor Review).
