It's a non rechargeable, 3V DC Lithium CR2032 coin cell battery, available most everywhere e.g. supermarkets. If it is <2.6V DC or >4-5 years old, replace it. The battery model is stamped on the battery if you wish to verify.
Removing the RTC battery (as well as disconnecting/removing the main battery) and holding the power button operated for 30 seconds resets the BIOS back to its default condition. This procedure is done when corrupted BIOS software prevents the laptop from starting properly. A corrupted BIOS is usually caused by a low RTC battery as the RTC battery maintains the BIOS when the laptop is turned off.

Given the location of the battery on the ''underside of the motherboard'', pressing the power button is not required, because you would have had to remove the motherboard from the case to access the battery. By the time you checked the battery's voltage, ''out of circuit'' and inserted a new replacement battery, a BIOS reset would have occurred.

Given the location of the battery in your laptop is on the ''underside of the motherboard'', pressing the power button is not required, because you would have had to remove the motherboard from the case to access the battery. By the time you checked the battery's voltage, ''out of circuit'' and inserted a new replacement battery, a BIOS reset would have occurred.
If the laptop does start OK it will show the incorrect date and time as the BIOS has been reset back to default. Once corrected it will maintain the correct date and time.
Here's a [link|https://www.youtube.com/watch?v=q2I-Dwlwkyg|video] that shows how they tried removing it without removing the motherboard but I don't think that it worked as the board had to be removed anyway. Too dangerous to try this, in my view, even if the main battery was disconnected, as damage to the motherboard could occur using the probe.

Here's a [link|https://www.youtube.com/watch?v=q2I-Dwlwkyg|video] that shows how they tried removing it without removing the motherboard but that didn't work as the board had to be removed anyway. Too dangerous to try in my view, even if the main battery was disconnected, as damage could occur using the probe.

Couldn't see it in your question, but try removing the RTC (Real Time Clock - aka cmos) battery on the motherboard. Given it's age it's probably not OK.

Removing the RTC battery (as well as disconnecting/removing the main battery) and holding the power button operated for 30 seconds resets the BIOS back to its default condition. This procedure is done when corrupted BIOS software prevents the laptop from starting properly.
A corrupted BIOS is usually caused by a low RTC battery as the RTC battery maintains the BIOS when the laptop is turned off.
Although given the location of the battery on the underside of the motherboard, by the time you check the battery ''out of circuit,'' a BIOS reset would have occurred because you would have to remove the motherboard from the case.
The battery model is stamped on the battery. Usually it's a non rechargeable, Lithium CR2032 available most everywhere e.g. supermarkets. If it is <2.6V DC or >4-5 years old, replace it.
