Re:Fan stays on when it's in sleep mode

I've got a similar issue with a twist. Lenovo Flex 5 14 AREO5 81X2. Anytime I shut the system down the fan runs at top speed until the battery is dead, which takes about 8 hours. The machine is completely unresponsive while it is in this drain down fan mode. The bios was updated via Lenovo website on first launch.

Hello, exact same problem here.  Than fan does not stop running at a high speed.  Whether in operation, or whether i put it to sleep.  My X1 Carbon 6th Gen is less than 3 years old.  Has had its system board replaced, and fan replaced by lenovo technicians and now it runs even hotter than ever.  These laptops are like jags.  You need 2 because one is always out for repairs.

Re:Fan stays on when it's in sleep mode

Hello,

 

I am experiencing the same issue on windows 10 with the all new ThinkPad T14s AMD (20UJS00K00). The sleep mode seems to work fine if the laptop is not docked, but attached to the powered Lenovo USB-C Travel Hub the problem arises. Upon entering sleep mode (blinking led on the lid) the fan suddenly goes berserk, full speed. After some time the machine does not respond anymore and won't wake up. That's when I need to shut it down completely. I checked all the drivers provided by Lenovo, I installed all of them. BIOS is up to date. But the problem remains. How do I fix it? This is really annoying, especially with a premium laptop like this one for which I paid a premium price.

 

regards

Hello everyone,

 

after searching the german forums I found someone suggesting to switch from Windows10 to Linux Sleep Mode in the BIOS settings. That worked for me. It may not be Lenovos fault after all, but a problem with Microsofts modern standby... simply annoying.

 

cheers

I’ve found a solution that has helped me a lot with the fan issue and overheating. In Lenovo Vantage I switched my laptop to “balanced” instead of “high performance“ mode. Now my laptop sleeps without the fan roaring 24:7. It still gets hot while in use and charging but it’s within normal parameters now.

I recall seeing the suggestion for 'Balanced' in a previous post or another thread but I can confirm that it didn't work for me. I had this computer on Hibernate and the fan was blasting away. As to the BIOS suggestion, I only wish I could give it a try but since my screen has been broken since December ཎ (yes, I've been trying to wrestle Lenovo toward a solution since then and after 3 on-site visits to resolve the issue which ultimately left me worse off--a keyboard that doesn't sink in completely so the lid can't be closed and a screen that doesn't return any picture where before it flashed occasionally and registered false touch screen input), I have no way of seeing what I'm doing. 

 

I genuinely regret the day I decided to buy this machine over a Surface Pro. I got fewer than 2 months of problem-free operation out of it before it began its descent toward electrified brick and the support has been far from great, having to talk to "special" people because it's a Thinkpad and not another Lenovo model and having to work through a separate service ticketing system. Good luck to you all, at this point the fan running ad infinitum is the least of my concerns.

Re:Fan stays on when it's in sleep mode

Recently, I've bought a new brand X390 Yoga. I've installed Linux Manjaro on it. Unfortunately, it never turns off the fan when my laptop goes to sleep resulting in depleting the battery.

As I noticed by this thread, some other brands had this issue solved by Bios update. If I am right, I am so confused why Lenevo doesn't upgrade the Bios for this issue. 

It's really disappointing as I rarely turn my laptop off-most time I suspend it.

Good luck. Once Lenovo gave their generic "update BIOS" message about three pages back they have stopped responding.
