Lenovo y50-70 blinking orange light and battery not charging

2018-01-15, 19:07 PM



I have a y50-70 that has been working pretty smoothly for the last two years. I am studying abroad in Italy and was told that my charger should have a built in power adapter, however when plugging into the outlet via an outlet adapter it immediately made a popping sound and started smoking. The charger was a replacement which had been working fine for about a year in the states, but I just assumed that this one didn't have the built in adapter and I drew too much power and fried it.


I ordered a new charger specified for my model from amazon Italy (with European plugs) in hopes that it would work....but no luck, and he charger is making a consistent soft hissing sound when plugged in. I am also getting a blinking orange battery light when plugged into the charger, but this is the only form of response I'm getting from my computer. 


After reading around my best bet is that I've blown a fuse or fried the battery but I wanted to see if anyone had a more confident diagnosis before I go shooting in the dark. Any thoughts?

Hi Horochowski5100,


Welcome to the Community Forums.


There is the power system checkout guide in the hardware manual (page 21-22) to help isolate parts and probable issue that you can try.


Personally as I see it, the machine does have power but fails to complete POST (power on self test).

Other than systemboard issue, it would be appropriate to have it checked internally for other points of failure as this may be the power board , dc in port and cable , board capacitors, CPU, ram etc.


Not much on the battery since we expect it to power on without any battery connected but can be removed to check if it was causing the short unless there are visible burnts marks inside.


I would suggest having it taken to a service center for a specific diagnostics if the power checkout guide lead to a systemboard replacement.


Hope this helps answer your query.
