I replaced the battery in my old Lenovo Thinkpad T500, but it is still dying after sitting for a few hours. OS is Win10 Pro. Even if I set the laptop to Hibernate, the battery still somehow dies. Any ideas how I can fix this? Thanks.
EDIT: The laptop dual-boots to Kali Linux, so I will try letting it sleep under the Linux OS to see if the battery still dies. I am thinking it is a Windows 10 issue that is killing that battery.
EDIT2: The computer is not going to sleep or hibernating when I close the lid.
