The Lenovo IdeaPad U350 was released in 2009 as a low-cost, thin, light laptop. It shipped with Windows Vista Home Premium (64-bit) or Ubuntu and features a 13.3" display.

Why is my laptop randomly shutting itself off?

Lately my IdeaPad U350 has been shutting itself down without any prompt or notification. It's not the normal Windows shutdown, either. The screen just goes black and it turns off immediately. Sometimes it will work for an hour before this happens, and sometimes less. I noticed that if I let it sit off for a while between shutdowns, it will last a bit longer. Any help is appreciated.

I have a Lenovo think pad and i can get it to run for 15 minutes and then it turns itself off even in bios bit it takes longer in bios. I tried to run a test to see if its the motherboard and i couldn't even get the test to finish to see. I have it plugged in and it still turns off. Battery was replaced a year ago. Now my laptop is a nice paperweight.

The following solved it for me....

To do it via the Power Options, right click the battery icon (or electrical plug icon) in the lower left corner of the screen, then...

1. Select a power plan and then click "Change plan settings"

2. Click "Change Advanced Power Settings"

3. Look for "Processor power management" and expand it

4. Expand "Maximum processor state"

You can now enter the percentage usage of the CPU while on battery and plugged in.

Note that it does not work the way you think it would work. Meaning if you set the CPU to 90% it will run at 90% of the stock clockspeed. No... it's not like that. For example, my i5-2410m has a stock speed of 2.3GHz. Turbo boost overclocks it to as high as 2.9GHz when stressed.

100% = Turbo Boost on.

99% = Turbo Boost off. CPU runs at 2.3GHz

78% - 98% = 1.796GHz

69% - 77% = 1.596GHz

60% - 68% = 1.397GHz

So you get the picture.

Thank you times a million for posting your solution!! I was so frustrated that my brand new laptop was shutting off but I haven't had a problem in months thanks to this fix!

von

Er... sorry for the dumb question, but what % are you meant to set the maximum processor state to? I've tried 99%, 100% and 90%, and I've still had my Lenovo Yoga 910 (windows 10) black-screen on me 3x in the past hour. (I had set it to 99% before because that reduced the fan noise problem.)

von

Thank you for taking the time to type the instructions. I do not understand how to know which % to select? Do I want turbo boost off? On? Do I set it low?

von

Thank you for the information!! I have the same problem. I would like to know what is the correct % I have to choose?

Thank you!

does this also work with acer windows??????

It sounds like your laptop is overheating. The first thing to test is making sure that your fan is working. If you don't hear it and can't feel any airflow from the exhaust vent, then either your fan or your laptop's fan controller (which is located on the motherboard) is broken. If your fan is working, then the thermal paste between the CPU and the heatsink likely isn't transferring heat properly. Fixing this will require disassembling your laptop and applying new thermal paste. I recommend Arctic Silver 5 or Noctua NT-H1 thermal paste.

I have a lenovo x220 and had the same problem. Altough I checked the temp and it wasn’t excessive I have just changed the thermal paste and it has been working for 5 hours without shutting down. Before I couldn’t use it for 20 minutes and afterwards it kept shutting down all the time, even when idle even in the bios. I found a forum thread where this was the solution for many people with the same lenovo.

Techs will tell you to change the motherboard. But it seems that this worked out for many people with this problem.

I've done the same thing to 3 or so laptops that were having stability problems like this. It makes an incredible difference. One of them would show the Core 2 Duo going to 90 degrees and then it would shut off, another would do it during CPU intense things and Windows update

I think a good indicator is to watch the CPU temps, idling at 60C is a bit high, even for laptops. After changing thermal paste it would drop down to 45-50c and jump to 70c max under load

My CPU temp was fine when measuring,

but still that was the solution Had been looking forever

Another way that should work: right-click the mini power icon on one end of your taskbar. Select Power Options. This will open a window with power settings in Control Panel. Select a plan. (with the newest w10 there should just be one unless you have a custom because it is programmed to be adjustable (balanced)). Click change lan settings then click change advanced power settings. In the new power settings popup expand hard disk and then expand turn off hard disk after and click the down arrow until it says "Never" do this for both battery and when plugged in. this is the solution i found after reading the original answer to this issue.

you dont have to mess with the processor at all bc thats not what is crashing

von

the hard disk is just automatically shutting down on default w10 settings (why is that default on only some?)

von

I did not find the last option 'never'.

von

^^ last option is location when you press the up arrow button then back down to "0", press the down button again and it will say "never".

In my case, something related to similar lines ..

In Power Options, Advanced Power Settings, "Balanced" power profile was active.

It was strange to see under this option... Processor cooling policy - On battery as "Passive", and Plugged in as Active.

Now I changed : "on battery" option from "Passive" to "Active".

I will keep watch on this now on.. Let me see how it goes !

Not really solve the issue on my side but upon reducing power consumption items like removing my headset and change to a normal mouse (not gaming mouse), then turning off my screen doesn’t show anymore

I have a Lenovo IdeaPad U310. After about an hour it turns itself off. There is a new SSD and windows 10 x64. It has current drivers. The processors are at a temperature of 50 degrees. The laptop seems fine, but it doesn't overheat, but it still shuts down. It also shuts off outside of memory, for example during a memory test. I use Memtest. Does anyone have an idea?

Hi,

Does it do this when the charger is connected or when on the battery only?

How long is it on for before it shuts down?

If it stays on for long enough, try creating a Win 10 battery report and check the status of the battery, just to eliminate it as a possibility.

von

I tried disconnecting the battery from the motherboard and using only mains power. The problem is still there, I have no ideas anymore and I think there is a problem with the motherboard.
