This guide is AWESOME.. Thanks! I have an iPAQ 1945 h1900, but this guide was the exact same for my device. I got as far as the taking the battery out without removing the 5th screw beneath the "warranty void" sticker. My only issue--do you know where to get the replacement battery?

IMPORTANT. The back up battery does not show charge immediately ( i don't know why ) Id read something before. When in April 2023 i swapped the old B U Batt for a known good one from another ipaq. At the end of the job . The level of charge on the b.up was zero. I charged the main batt to 100% then removed the ipaq from the charger and left it for a couple of hours . When I next checked it there was 100% on both batts....
