![]() ![]() ![]() > I resorted to removing the power plug from the PC every evening after it kept turning itself on during the night semi-randomly. It seems this mishap caught a lot of people off guard. It was very hot when I took it out of the bag later, fortunately it was just in time. I too had my (also Dell) laptop overheat after I had suspended it, thinking it was turned off. I won't even try to ask Dell (Dell 8500 PC), they are only good at sending replacement hardware but unable to answer anything related to software (as long as they do the former I came to accept the latter). I spent a significant amount of time going through Windows event logs to find what caused the wake-ups, fixed some, others were too broad to do anything about it. It was in "suspend to disk" mode, whatever that is in more technical power-save jargon terms, not just "suspend-to-ram".

Edit: And I should add, it's crazy that there's not a way to disable this if it is doing something "useful".Įither way, under Linux the latter doesn't happen, and the laptop sleeps very cool. I've never been able to figure out if this Windows actually doing something useful in "modern standby" like Windows Update, or whether it's a bug. The seems to be a second problem, specific to Windows, that when in S1 sleep sometimes the power consumption is high (of order 10W), and this causes the laptop to get very hot if not well ventilated. ![]() In S1 sleep, the laptop can average something like 900mW of power usage, which is enough to annoyingly knock a few percent off your battery overnight, but not enough to make the laptop warm, even in a bag. But I don't think this is the direct cause of the overheating. I think there's two separate things going on:Īs others have noted, S3 sleep isn't supported, only S1 "sleep to idle" sleep. I have an XPS 9500 and have found this infuriating. ![]()
