Hi, My T430 suddenly powers off. It does not show any sort of warning, blue screen of death or anything else. It just powers off completly. And it does not turns on until the battery is removed and installed again. If it is running on AC power i.e without battery, the power cord has to be plugged out and again plugged in to make it work again. The time interval to turn off is completely random, sometimes 1 min, 1 hour, 10 sec etc. And it can happen after boot, in bios or anywhere else. I have confirmed that it is not a heating issue by running a stress test for more than an hour and it worked fine. I have also tried changing RAM, removing HDD, removing ultrabay disk drive, but doing these does not produce any difference. I have also tried pressing the power button for 60 sec, but does not make any difference.
I have 5 E540 touch screen and 2 regular E540 Thinkpads that all are shutting down at various times. If I remove the battery it seems to cure this disease. I have brand new batteries and a couple original batteries so I don’t believe it’s the battery. I monitor the temperatures and they aren’t near hot enough to trigger a shutdown. I’ve done the removing battery, charge cable then pressing the power button and this doesn’t change anything. I’ve updated the BIOS with still no success. I’ve change the power settings including setting the processor to 100%. Still nothing doing. I’ve also installed the latest Power Management software and this does’t seem to help either……. So what’s going on? Does anyone have a solution. I purchased these laptops, upgraded them all to more RAM and i7 processors for resale and I cannot sell them in this condition. BTW, I checked one unit with the standard i3 that came with this model and it does the same thing. It’s definitely not the processor exchange and I cannot believe that all my motherboards are defective. Again, What’s going on??? My last guess is maybe it’s a Windows 10 glitch.
