Did you buy HP genuine external battery? Charge it 2-3 hours before use.

The video is a little bit black out. It would be much better to show morclearly.

It is important steps only partaining the assessment of the cmos battery, without unnecessary diasembly, because the objective is the replacement of RTC battery.

Many thanks.
