Yeah it does. Instructions for accessing it would be in your user's manual.

Checking the backup battery
Do the following:
1. Power off the computer, and unplug the ac power adapter from it.
2. Turn the computer upside down.
3. Remove the battery pack (see “1010 Battery pack” on page 59).
4. Remove the backup battery (see “1130 Backup battery” on page 79).
5. Measure the voltage of the backup battery. See the following figure.
Wire Voltage (V dc)
Red +2.5 to +3.2
Black Ground
Red (+)
Black (-)

Nope. It has a 1500W Silverstone PSU powering the BIOS chip.

OT: Ofc. Is there even a laptop that doesn't have one?
