Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

The average laptop battery is good for around 400 recharges cycles. After that, it starts to lose its capacity to hold a charge. This is about one and a half to three years of battery life for the average user. As the rechargeable battery begins to fail, the running time of the battery begins to decline.

I'm tested the battery with HP support assistance , it say Discharging 10%, primary Battery: OK.

but the hidden icons show 10% all time, I can't turn on the computer without plug in charger, also will turned off when plug in charger during use. But as soon as the unit turned on, it will run about 3 to 4 hours on YouTube.

Thanks for you reply.
