@Rafeeqhamadamin
Peace be upon you!
Thank you for posting on HP Forums,
The Riddle_Decipher is at your service.
I understand you have an issue with the battery of your device,
I'll be glad to help you out, however, for an accurate solution I will need more details:
What is the product number of your device? Use this link to find it: http://support.hp.com/us-en/document/c03754824
(Ensure you do not share any of your personal information such as serial, phone number, email ID, etc...).
Have you attempted any steps on your own before posting on the HP Forums?
What exactly is weak? does the laptop turn off immediately after the ac adapter is disconnected?
Please reply with the details for further assistance.
Eager to help!
If I have helped you resolve the issue,
feel free to give me a virtual high-five by clicking the 'Thumbs Up' icon
followed by clicking on 'Accepted as Solution'
And Have a great day Ahead!
