Windows 10: adapter not charging the battery

Hello,


I have Lenovo Y520 laptop. somehow i let the battery completely drain and the laptop got shut down. Since then my battery does not charge. even when i left the adapter plugged in for quite a while the status still shows "0% available, plugged in charging".


I bought this laptop few months back, so it is almost a new one.

does draining battery completely has adverse affect on battery?


Please help me with this issue as i am unable to run my laptop without plugging in adapter.

:)

 

New battery not charging


I have an Acer Aspire V3-771 laptop (which is three and a half years old) with its original battery. As the battery is not holding the charge for as long as it used to I decided to replace it. I inserted he new battery, which already showed a charge of 60%, and let it run down to the point when the laptop turned itself off. However, when I tried to recharge the battery, the battery icon showed "6% available, plugged in, not charging". I contacted the supplier of the battery and they sent me a new one. This showed an initial charge of 93% so, in view of my problem with the previous battery, I decided to try and charge it up to full capacity before letting it run down. But as soon as I tried this the battery icon showed "93% available, plugged in, not charging". So I unplugged the charger and again let the battery run down until the computer turned itself off. I plugged the charger in again but then got "6% available, plugged in, not charging". I have no problem charging the old battery, so can anyone please suggest what the problem might be? I have tried taking out the battery and unplugging the charger and holding down the power button for 30 seconds, but this hasn't worked. Grateful for any advice.

 

Battery charging advice


Older batteries, based on NiCd (Nickel-Cadmium) had many drawbacks. like charge "memory" and easily being overcharged and warped. Needed careful planing and charging to keep in shape. Best way was to keep them fully charged and out of laptop when not needed, run from adapter only. Than you needed to plug them in and discharge and recharge once a moth.
Newer laptops and their batteries have automatic charge system with sensors and intelligent maintenance so no need to unplug at all. Added bonus is that when plugged in it switches to full performance and on battery only it kicks into battery saving mode reducing performance.

 

01 min to full charge but battery not charging





My laptop battery icon is showing this and still not charging since two days. If i plug out the adapter, the percentage showing decreases. But when plugged in, it is not increasing and still 34% since two days. What should i do to make it charging again?
