Answer to: My Laptop won't charge the Battery nor Boot on it without AC adapterHello, I have same laptop since 5 years ago and still working fine after RAM, wi-fi and SSD upgrade, had the same intermitent problem twice. I solved it replacing the charging DC Power jack (was loose, buy not fully broken). Later when upgraded to Windows 10 sometimes it did not charged the battery. I discovered in this case the reason was that not all devices got the proper drivers installed. Get the chipset drivers installed: Intel 5 Series/3400 Series Chipset Family (get the latest Intel drivers here: https://www.intel.com/content/www/us/en/...) Get all the device drivers updated, somehow if not all the devices are correctly installed in the Computer Manager (right click on “this PC” icon on windows explorer), the battery have a exclamation icon, and it won’t charge or have problems detecting the battery itself.
