Laptop reboots randomly, no bsod or error message

[berkguy]

I have a lenovo u400, my processor is an i5 and it run around 50 C when doing normal browsing. runs at 60-70 C when watching movies or light gaming. My Tj. max is 100 C, never seen it pass 75 C. I just bought my laptop a month ago, so I don't know what's the deal. When I touch the bottom of my laptop is feels pretty cool.

I have ran malwarebytes and MSE and have not found anything. I have also ran a memory test and everything looks fine.

It usually happens when I'm watching a video from a website. My computer just reboots, no bsod or error message. I don't know what to do next. What can I do to troubleshoot this further?

Hi Berkguy

Based on your logs...

Most of shutdown or reboots are caused by your graphics driver... ATI Catalyst.....

The server {E10F6C3A-F1AE-4ADC-AA9D-2FE65525666E} did not register with DCOM within the required timeout.

which is related to

ATI EEU failed to post message to CCC

Suggest you update your ATI drivers from the manufactures website...

and a few are related to system getting really high temperature.

Kernal Power .....

ACPI thermal zone ACPI\ThermalZone\TZS0 has been enumerated.

Again since you said .... the laptop looks cool...... and based on the above errors.... i am sure these shutdown were also due the drivers putting the graphics at high temps.....

Let me know your feedback
