Great guide. Thank you Carsten! Might I suggest a small correction to the grammar in the intro? The first paragraph would be better written as
"If the computer cannot retain date and time, and gives an error on bootup, then the Real Time Clock battery needs replacement. This guide shows how to perform RTC battery replacement.
The RTC battery is located at the bottom of the mainboard, which will need to be lifted out before the RTC battery can be replaced."
