On MobilePro systems, which both batteries have fully discharged, the user must perform a hard reset after charging the batteries for approximately 10 hours to ensure proper operation. If the systems fails to power on the user must perform a "hard" reset to initialize the power management circuitry.

Lithium ion battery does not last as long


There is no such thing as a memory system in your battery. If you charge the battery until the green light on the charger comes on, that is as much as the battery can/will safely charge to. With Lithium batteries, they will fully charge whether they are at 75%, 50% or 10% capacity when placed on the charger and discharge to 0% if you use them that long. If you need the battery before the green light comes on and you use it, it will still fully charge when replaced on the charger. All batteries do discharge at different rates. Most not noticeably but a few will discharge fast enought to be noticable. If it affects your usage of the tool, you may want to exchange it or get it replaced under warranty because it will only get worse with age.

How to discharge battery


"Calibrating" a laptop battery is one way to increase the lifespan of a battery that doesn't last long. The procedure involves two steps: fully discharging the battery, then then fully charging it immediately thereafter. It's important to note that a full discharge doesn't mean you drain your battery until your computer powers off, but rather that you deplete it until it reaches a level of approximately 3 percent capacity, according to BatteryCare.com.

1. Charge the laptop battery to 100 percent. Allow the laptop to sit plugged-in and fully-charged for approximately two hours.

2. Click the "Battery" icon in the lower, right corner of the Windows Taskbar and click "More Power Options." Click "Change When the Computer Sleeps," then click "Change Advanced Power Settings."

3. Scroll down to "Battery" and click the "Plus Sign" icon next to it. Click "Critical Battery Level," then click the arrow to decrease the number to "3." Click "Apply," then click "OK."

4. Unplug your laptop and continue using the computer until it reaches 3 percent, at which point it hibernates automatically. Allow the computer to hibernate for at least five hours, then plug it in and allow it to recharge fully.

I hope you find it very helpful. Thank you for using fixya.

My hp pavilion dv4 laptop's battery cannot sustain even for 1 hour.please give some ideas to maintain the battery and is there any remedy for this issue.Also which is better among, using laptop always...


If the battery appears to be charging, the drop in the time it sustains power is likely due to a faulty or old battery. Eventually it will appear 100% charged and drop to zero in 5 minutes or less. I would think you need to replace the battery.

If you want to maintain the battery properly, it is best to remove it once fully charged and use on ac power alone. If using the laptop on battery, remove the AC connection and allow the battery to fully discharge before recharging it ( there is some debate on this method, other may disagree)

My Archos 605 will turn on for a second and then turns itself off


Sounds like the battery is fried or that the system has interpreted that the battery is fried.. Have you tried a 15 second reset. Stick a pin in the reset hole along the bottom for 15 secs (or longer) to allow full discharge and reset. Recharge immediately for about 4 hours with the system completely shut down (press on/off button 15 seconds until blank). If there is still a problem try for a long reset again. If it does boot check the battery condition and how long it takes to die. Once a battery decides its had enough they can go quite quickly and die completely. Do you run the Archos whist it is in the dock or while the charger is plugged in it, I have found that running current through the battery like this can shorten the battery life considerably. I tend to charge fully and then discharge fully, for some reason this keeps the battery fit and allows the system that monitors the battery to have an accurate appraisal of it's true condition.
