The solution was to find the + and - terminals for charge input with a meter and hook the battery to a 5v 200mah "wall wart" from an old phone and keep an eye on it to be sure not to get too hot (no warmer than the outside of a porcelain coffee cup with fresh coffee). most lithium ion battery packs will not charge through a "smart" charge device if they are completely discharged because of the built in battery protections not being able to detect the empty cells because there is no internal power to do the initial check. The battery went below it's minimum safe voltage and has blocked charging. I download the BIOS file, and keep the laptop model serial numbers and stuff in hand and then do what? Sorry, if it sounds really noob, but I am kind of at a loss! I think it's necessary to update the BIOS, but do you think it just might solve my problem?Īlso, how do I update the BIOS? I haven't done it before. So, I checked, and it turns out the my BIOS is from 2016 while there is a perfectly recent (April, 2018) BIOS update available for my laptop model on the Lenovo official site. So I don't think the adapter is at fault here.īut while searching for a solution I came to this point - sometimes updating the BIOS helps. The adapter is working as I can now only run the laptop while plugged in.
The Power option is at balanced default settings. I am guessing the battery may be at fault.
No estimated time to fully charge up is shown. The time to fully charge up showed a bizarre 5 hours 20 minutes.įrom today, it is stuck at 0%, plugged in and charging.
Then, later on, it started to get stuck at 5-6% showing plugged in, charging, but it would not go up. But it would charge up perfectly, or as normal! It runs Windows 10, and has been a smooth sailing experience until a battery issue came up from the last 5 days.Īt first, the battery % would drop very quickly.
