T470p power issue

2019-03-09, 9:59 AM

Hi Everyrbody;

 

I have a full spec T470p, and it's a few days that when I connect it to the power source, the power LED blinks 3 times every 10-15 seconds.

 

I know this is the confirmation of a power source being connected, so it thinks the power is connected / disconnected every 10-15 seconds. I changed the battery, and changed the power brick ( I have access to a few thinkpads in the office ) to check if the problem is from one of these items, but no luck. Also the same happens when on the dock, so the power connector / port should be good too.

 

I read in this forum that people had all sort of strange power issues with T470p, I thought maybe I post it here before sending it to lenovo for repair.

 

Thanks!

I think getting it repaired is right.  It sounds like a problem in the power circuitry
