Hi,
if you need to replace the flat CMOS battery in your ACER Extensa 6530 laptop but are horrified by only thinking of the task of stripping the machine down to the bare motherboard just to reach the dead cell (as intended by the manufacturer),
here is a 5-minute-solution without any disassembling (actually not even a screwdriver needed) I explain in my short YT video:
https://youtu.be/LgbV4nwZYYoI tested it on an Extensa 5630 only, but according to the service guide from ACER it should work on the Travelmate 5730 series too.
Best regards
Micha
