I bought a TC885 about 3 months ago and the "Coil Whining" problem existed since day 1. I thought it was normal until the electrical noise became very obvious and kept bothering me. It's definitely noticeable. I did some research online and realized it is Coil Whine. Now obviously it's too late to return/exchange it to the vendor so I contacted Acer Support as it's under warranty. I was told I had the option to ship it in but I have to cover outgoing shipping cost. In addition to the shipping process, it may take 7-10 business days to look into the problem. I do need the device for work at this point but also urgently would like to have it fixed.
I have a couple of questions here.
1)Will Acer technicians take "Coil Whine" issue seriously? I don't want them to call me saying it's normal and won't effect anything (the whining is quite noisy) after the long shipping process which is costly as well.
2)Has anyone experienced this? Any solutions? I see some posts regarding Coil Whine for Acer laptops but fewer for desktops.
After a 2-day study, I found it can lessen the noise if I turn off the Turbo boost by decreasing "Maximum processor state" to 99% or less. But the problem is it doesn't completely get rid of "Coil Whine" and I don't want to lose any performance of my brand new device. I probably have to contact Acer support again soon.
Any thoughts and/or recommendations would be much appreciated. The Coil whining/ electrical noise is truly annoying! Thanks guys.
Although the problem is not resolved yet, a kudo to Acer support online chat team. The guy named Carlos was patient and courteous.
