Basically this is rubbish... check out the other threads relating to batteries, power etc. Sony's are perfectly happy to be left charging and do NOT discharge unless you use a computer which is set to sleep/hibernate, switching off its USB ports then it will start to discharge. All of my Sonys, and the ones used by friends, are perfectly happy to be left charging overnight, over the weekend, for a week, whatever... they have circuitry which stops the possiblilty of overcharge and certainly do NOT discharge unless you turn the PSU or computer (USB port) off.
By all means press the reset before you charge (or after) as it simply resets the machine to its normal state without affecting anything else. After that just charge it, either with a separate wall charger or by computer... just ensure computer is set to stay awake and keep USB ports active (some do keep ports active) and do so for at least 4 hours (red light should go off) which'll probably give you 80% charge or do as I (and many others) do and charge overnight for 6-8 hours (I'm not getting up early to disconnect it for any voodoo science ideas) or more... if you want more precise info then google "lithium ion batteries technical specification" or similar and get the full accurate info from the battery manufacturers...

Just make sure to reset the reader before charging it,(just push the reset hole and it will not delete anything) then get it to charge for no more than 3 o 4 hours and see if that helps or the behavior comes back
