I have a new tx2, and i wonder when to recharge my battery.
Should i wait until it is 100 %discharge or always keep a small amount of charge i.e.... recharge at 25 %
Should i keep the tx2 always plug? Meaning the battery will be always near 100%
So what is your strategy in regards the battery?

Thanks' you Cheryl G and Huffer
I review our link and other information.
Wonder if someone from HP could confirm if i am right in understanding.....
If i do not indent to use my battery because the Tx2 is plug for a long period of time (they talk about 2 weeks period has a reference or more), i should remove the battery. This will let it discharge slowly.
Same is if i intensely use the Tx2 on a daily basic while it is plug (3D game or CAO application).
Basically what i understand from that we should allow the battery to have some rest and not be 100% of the time charge at 100%
Make sure the battery is 100% charge when unplug. Store it in a normal environment and test it avery three to six month to avoid discharging below the mark or 50 to 25 percent.
Calibrate the battery once a while (1 to 2 times a years) so the indicator will show a more exact reading of the charge inside the battery
On the other hand if i work intensively on the battery, i could use it until it reach about 5 percent then i should recharge it.
If i intend to swap battery and no possibility to plug it while doing the swap, place the TX2 in hibernation mode then change battery. ( i saw no mention how long the Tx2 can stay in hibernation without battery 30 sec - 1 minutes???)
Has a reference i had a Toshiba Satellite 2450 one of the last pentium IV before the wave of dual core he's about 8 to 10 years old and the battery is able to keep its charge for roughly 30 minutes ( when new it was 3 hours). It was plug all the time except few exception. wonder if i would be able to keep my TX2 for that long and have a comparison........
Thanks' again, hope this will help others,
Leave your story about your battery

If folks at HP monitor this thread, here one suggestion
Have a external charger for TX2 battery
Base on the info i found on the net, i would suggest three operations modes:
This mode will keep the battery charge between 20/25% to 75/80%. This will allow users to store the battery for a long period of time ( has a reference someone who will not need the battery for 2 week or more). Once reach the 75/80% charge, the battery will discharge on it own slowly.
This mode will keep the battery charge between 75/80% et 100%. This is when users are on the move and do not whant to keep the battery plug to the pc to avoid the heat of the processor. or those who have two set of battery they can swap or they swap battery but not so frequently.
This mode will keep te battery charge at 100% ( it will mimic the behaviour when battery is plug inside the PC) this mode will be usefull for those who constantly use battery and need to swap them frequenly. or for those who know they will need a full charge of in the next hour or so.
The charger could be link to a pc to program the three mode. always in extend mode except at 7 am switch to a manual mode to have a fully charge battery.
All this to ensure that the battery will discharge has slowly has possible and that we will keep the necessary amount of charge to meet our individual needs.
HP would like to hear from you
P.S. if idea pass thru i would hope you will think about be for that suggestion

How to discharge and charge HP tx2 battery
A typical charge and discharge cycle is as follow:
1. Install HP battery into your laptop
2. Disconnect the AC adapter and use your laptop until it itself shuts down. In this situation, the battery is fully discharged.
3. Connect the AC adapter and HP battery should start charging.
4. Charge until HP battery is full.
New batteries are hard for the device to charge; they have never been fully charged and are therefore 'unformed'. Sometimes the device's charger will stop charging a new battery before it is fully charged. If this happens, remove the battery from the device and then reinsert it. The charge cycle should begin again. This may happen several times during the first battery charge. Don't worry; it's perfectly normal.

When you suggest to remove the battery several times during the initial charge (new replacement battery for our dv 8000), should the power cord be plugged into AC and the laptop or should the power cord be disconnected when the battery is removed and replaced? Thanks
