Do you have other item in the background running which will drain battery also.
I doubt that it is Win 7 fault but again, I am not there to see what else is going on.
From the Wikipedia article on lithium ion batteries:
"Shelf life
Charging forms deposits inside the electrolyte that inhibit ion transport. Over time, the cell's capacity diminishes. The increase in internal resistance reduces the cell's ability to deliver current. This problem is more pronounced in high-current applications. The decrease means that older batteries do not charge as much as new ones (charging time required decreases proportionally).
High charge levels and elevated temperatures (whether from charging or ambient air) hasten capacity loss. Charging heat is caused by the carbon anode (typically replaced with lithium titanate which drastically reduces damage from charging, including expansion and other factors).
A unit that is full most of the time at 25 °C (77 °F) irreversibly loses approximately 20% capacity per year. Poor ventilation may increase temperatures, further shortening battery life. Loss rates vary by temperature: 6% loss at 0 °C (32 °F), 20% at 25 °C (77 °F), and 35% at 40 °C (104 °F). When stored at 40%–60% charge level, the capacity loss is reduced to 2%, 4%, and 15%, respectively."

BTW, I know it sucks. I'm pissed my warranty with Dell that I payed so much for does not cover this. I was expecting all hardware to be replaced when a problem happened. Now I have to pay out of pocket a new battery, when I didn't think I would have to for two more years.
Hey Howling Wolves. I like the new avatar. Didn't realize it was you at first.
Som, until your battery reaches the state mine it in, you should be okay. It if it last over an hour, don't worry about it. I saw you said it is about a year old. Which side of a year is it on. If its under a year old you may be able to get it replaced for free. Be warned, the battery usually has a separate warranty from the rest of the computer, so you may need to look that up.
Also, atbatt.com has a 9-cell battery for your laptop for 57USD, if you decide you need to go that route in the future.
If it were my system, AND IT'S NOT), I would drain it, charge it overnight and see what the meter says.
Like Petey states the cost of batteries are not that expensive.
Anyway Som, hang in there and keep us posted as to the final outcome.
i think I'm going to try that too just to see. I've drained plenty of times, but never recharged it without also starting the computer. I recommend trying it too, som.
Hello Som, and welcome to Seven Forums.
In addition, you might run a Power Efficiency Diagnostics Report to see what the results say. It has a "Battery analysis" section to help you get more information about your battery.
Hope this helps,
