New L15 keeps restart / reboot automatically

2021-01-17, 16:53 PM

my 1 week old L15 Ryzen 7 Pro 4750 keeps restarting / rebooting to "Sleeping Mode". Even when I try to move it to other working spot, it will switch to "Sleeping Mode". I have ran Diagnostic on the laptop and no issue found. I have been using Thinkpad laptops in the past 16 years and I have never encounter such problem. Please kindly assist on this problem.  Thank you!

Hi 

It looks like a hardware problem. Could you provide which diagnostic item you did?  please provide a photo or screenshot of the diagnostic result. And you can also ask local service center to examine your system. Thanks.

No....it won't work. still the same problem. i also bought another L15 with Intel i7 and so far no problem. But the L15 Ryzen 7 pro really make me disappointed with this kind of problem. I have never encountered any problem with my previous Thinkpads in the past 16 years. And my W510 still can run properly even after 11 years. Please kindly assist if there is any other solution to solve my problem. I have ran Stress Test on the processor and it could not finished the test and shut down half way. Thank you.

Hi,

 

I have already sent it to local service centre and this is also my first time to go to Lenovo Service Centre in 16 years of using Thinkpads. This L15 AMD breaks the record to broke down in 5 days. Thank you.

 

* I have just received a call from Service Cente. The Technician said motherboard problem. They will replace the motherboard and this will take a week to wait for the new part. Motherboard broke down in 5 days...think Lenovo needs to review their QC.

I have sent the laptop to Lenovo Local Service Centre and they have replaced the faulty motherboard. Other than the hassle from the faulty motherboard, i am happy with the L15 AMD performance...hopefully no more trouble for the next few years just like my old W510 that is already 11 years old and still running now. Thanks!!!
