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.

    That doesn't make you a hardware diagnosis and repair specialist.

  • ...also, this laptop is quite old, so it would instantly be "totaled" (not cost-effective to fix) if I were to take it to a shop for service.

Boot to linux, and issue upower -d. It will report directly original and current capacity of the battery. Try halting the machine, removing the battery, and pressing power to drain the system. Then start again. A thinkpad will not necessarily discover a new battery's capacity (if greater or smaller than the old one's), without a few whacks and boots.
