The fan appears to be able to spin at reasonable speeds, since it reports 3900 RPM at some times. Based on previous experience, if the fan sensor is as accurate as before, this report should be taken as exact. However, this fan speed is only reported for a very short amount of time, as if the cooling policy specified to turn the fan to full speed only between 60 and 62°.
Question is not so much if it doesn't overheat anymore but if it takes longer. I'm not using the compressed air as I find it's pretty much impossible to really clean the parts properly with it. It just doesn't generate enough force. Especially in spaces that are enclosed a lot.
I've had issues like the one described in the OP and blowing compressed air helps a lot. Of course it does depend on how tightly packed the components are inside the laptop, in my case not very tight, but it should have made a bigger difference. I'd guess the reported experience does put the software (BIOS probably) in a very suspicious light. Thing is, if you can't get it to work right in Windows even, there's little chance of finding a software fix for it. Most BIOS firmwares are quite tuned for windows, and if windows is also failing it does show a very pervasive bug. If I were you, I'd report that with your vendor. Seems like a hardware or firmware issue that they should be able or at least try to resolve. Even if it's just dust that the compressed air didn't unclog, they'd be able to disassemble and properly clean it. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
