P51S Power button flashing - Sleep mode issue

Hello - I have about 50 Lenovo P series Laptops running in our comapny and within the last month, 2 - P51S same make and model has had power up issues.Users reported that they "control +alt+ Del" to lock out their laptops and when then returned the laptop was DOA.

 

The signs are that the power power light is flashing every second ( Indicates in sleep mode)- FAn attempts to start but does not.

I have tried plugging in different AC power adapter, disconnecting both external and internal batteries. No change. I have openned laptop and disconnected SSD, Wireless card, ROM battery, fan, speakers etc testing and no difference. I have tried to discharge by removing all power and and tapping power button 10 times and hold in for 30 seconds. No change.  I find it strange that 2 identical laptops would suffer the same issue at the same time?? Looking on internet - this looks like hugh problem that maybe linked to the motherboard issues on this make and model.

I have called Lenovo and since out of warranty - sorry.

So please help if anyone has any other ideas to try.

 

Thank you in advance

Re: P51S Power button flashing - Sleep mode issue

After researching on the internet this appears to be a known issue with the motherboards on the Lenovo Thinkpads P51s with dual batteries. Unable to locate any replacement motherboards - We now have 2 Lenovo Thinkpads that are paperweights.

 

Repairs will exceed the value of the laptops - Great Product as these units survived just long enough to make it pass the Warranty period.
