So my laptop just stopped charging. Initially I had to adjust my adapter repeatedly for it to charge so I bought a new adapter which didn't fix it. It gradually got harder to charge until one day it stopped completely. I have tried removing the battery and plugging it in but that didn't work.
I also tried replacing the power jack which didn't fix it either. What should I do next ?
If you are not able to start the laptop even when changing the battery and the power cord, probably the issue is within the motherboard itself. You should bring your laptop to a PC technician to test it, but before that, you could take out the hard drive. Please, do so only if your laptop is out of warranty, otherwise, it would void the warranty.
Once you have taken out the HDD, you can connect it as an external hard drive via SATA-USB adapter, you could try to extract the data from it in order to make a backup on different place. If your MB needs replacement, you should reinstall the OS once again when you get the new one.
