Battery suddenly turns off

my laptop is lenovo z510 updated to win10 from 8.1 with a built in battery, suddenly the battery monitor started not to descend the charging percent, 100% alltime and then suddenly it turn off, and when i charges it it appears 0% that is fully consumed,
the battery life is the same in time but its always 100% till it's fully discharged.

after several times i tried press on power button to turn it off and then the rebooting it, it became descending the percentage but it turns off suddenly in 10%, then it became worse at 20% and then it became 30%.

its the same time to consume the battery but it descends so slow and then it suddenly turn off and i can't deal with it.

would some body help??

 

battery issue in my lenovo g50-80 laptop suddenly power drop from 30% to 6%

Hi,

There are several possible reasons as to why the battery power levels on your laptop would suddenly drop in in percentage. This could be caused by an update that was installed or system files that got corrupted. For us to resolve your concern, kindly answer
the questions below:

• We would like to confirm if there were any changes made or updates installed on your laptop prior to the issue occurring?
• Is there a specific number when the battery percentage being displayed drops in value or is it just randomly lowering the displayed value?
• Which version and build of Windows 10 is installed on your laptop?

We look forward to your response to our queries.

 

Battery is probably failing. Replace battery. You can get new one from Ebay.
If you see the same behavior with a new battery, then there is a problem with the charging port or power adapter.
