Laptop not charging

[Jowi1999]

Hello, hoping I can get some diy advice here. I have a Lenova v330 151 KB laptop I purchased Dec 2017. 3 weeks ago the laptop was drained to 38% while charger was plugged in - not charging. I read online to remove battery and hard reset - didn’t fix issue. Another source said to run a bios update - didn’t fix issue. I purchased a new charger ( compatible, as Lenova all out of stock ) and it was charging great for about a week and then back to the same issue.
I just ordered a new battery hoping it’s as simple as that, but wondering if anyone has any input in the event the battery doesn’t fix the problem. Months before the charging issue occurred I was noticing that my computer screen would Randomly fade in and out from dim to bright.
Thanks

Hi,

It sounds to me like a battery issue. If replacing the battery doesn’t fix it then I am all out of ideas unfortunately.

Thanks for your reply. Crossing my fingers that will fix the problem. I will update in a couple weeks.

also concur the new battery should fix it as it definitely sounds like it’s the battery or the charger.
the random dimming of the screen would be the hardware detecting (and not detecting) the charger plugged in and adjusting the brightness accordingly.

Have you tried the Windows Battery diagnostic?
Open a Command Prompt as administrator.
On the prompt, type
powercfg /batteryreport
and press enter

When was the last time you calibrated the battery?

I recommend creating a specific power plan for this rather than editing a current plan.
