SSD discharge battery on power off

[Vincent Onelli]

Hello.
I have an HP laptop envy dv7, it came with 12 GB ram, windows 8
installed on 1TB conventional drive every thing works good. I decided to
replace the conventional HD with a SSD 450GB and installed fc19 again
every thing works good, except if I turn off the laptop and leave it off
for a couple day the battery is discharged. I reinstalled the
conventional HD no problem. I purchased a second SSD 250GB same problem.
Any body had a similar experience? any idea how can be fixed?
I contacted the manufacture, they never heard that problem.
I appreciate any input
Vinny.
