i got the big extended battery for HP Envy since i can only get 1HR of life from the regular one (fast cpu)..
after getting the extended battery, after 1-2 months of use, it would randomly just shut off power, and not come back on until i took all batteries out and put regular one back in.
the problem gotten worse and worse to the point where it would shut off during boot.
so i finally had HP replace the extended battery.
i used the replacement battery scarcely because i had a bad feeling about this.. and as this was maybe 8th time i used it, the power off just happened again. after resetting the initial battery (and keeping the extended off) i was able to power back on.
any ideas on how to troubleshoot what it is before i call HP?
