15 years old today, wow, a BLAST FROM THE PAST .
one more old PDA, that nobody wants. legacy.
omg , they still support this "THING"
took me 15seconds work and 1st google hit,
https://www.asus.com/supportonly/MyPal%20A620/HelpDesk_Manual/
oddly no battery removal page.
so did you open that hatch first?
remove all things under that hatch CF card
and first look for screw there.
is this your first time ever doing things like this, seem so
we use plastic,cell phone pry bars. to do this.
all screws out and pry.
btw some PDA have 2 batteries, and both will be bad if 2 are there.
you do know that right?
one can be the coin cell inside dead.
wow no service manual on 620.
its only worth $5 or less at Garage sale. it scrap it. it is worthless.
goggle shows nothing this old, on topic
all screws out, pry bar it. (sold for cell phones)_
or use Guitar pick as pry.
better yet trash it and buy use Android cell phone for cheap.
PDA are like , APPLE 1 PCs. now.
