Power Button flashing, can't charge or make laptop work on charger! HELP :(

Hello Dear Lenovo community! 

 

I have an issue that maybe anyone can help me with. I have Lenovo B50-30 Serial:***********. It's about 4th year of usage and perfect so far, but approximately these 2 months I noticed power button starts flashing all of a sudden. Upon flashing battery stop charging. I was unpluging and pluging back again and it worked normal. Unfortunately during these two month this occured more and more often and it needed to do plug operations after every hour, after every half hours, after every 15 minutes and now it's dead. As soon as I plug charger power button immadiately starts flashing. I thought it was battery first, but laptop turned off after couple of mniutes working on charger without battery.  I noticef this was occuring during gaming on laptop. Generaly DOTA 2. CPU temperature maximum heat was 82 and video card 74-76. 

I tried different chargers result is the same. I tried different battery result is the same. I tried power shut down, like removing battery and pushing power button for 60 seconds, but no possitive result.

Here's the vide on my google drive of laptop and how it behaves. https://drive.google.com/file/d/1308AVwDsP9pt4hxM0zVOny68e_H5UYPW/view?fbclid=IwAR2GseZw5-cZjC291CZI...

 

Please share with your opinion hoqw can I fix this. 

 

Thanks in advance.

Hi GeorgeKay,

 

Welcome to the Community Forums.

 

Power off and disconnect the battery to press down the power button (12 seconds) to drain flea power again.

 

You can remove the harddrive and do back up. Trying one ram at a time just to use the novo button to power on to access the Novo menu for booting to BIOS.

 

Having checked with known good charger and battery that both failed would leave us with probable board issue. You may have tried reapplying thermal paste and cleaning fan but it may be best having it checked in a service center for board level check.

 

Update us how it goes.

 

Regards

So I figured it out by myself. Upon diassembly I found out that charging hub have some contact issues in wires so I twisted them a little and voila it worked.

I would caution doing the "Twist" on it... if the wires are bare it could short out and destroy any attached items.

Get a replacement transformer (not that expensive) just to be safe.
