Did u Upgrade your notebook to Windows 7 & getting battery issue?

Windows 7 makes use of a feature of modern laptop batteries which have circuitry and firmware that can report to Windows the overall health of the battery. This is reported in absolute terms as Watt-hours power capacity. Windows 7 then does a simple calculation to determine a percentage of degradation from the original design capacity. The Windows 7 the notification is a battery meter icon and notification with a message “Consider replacing your battery”. This notification is new to Windows 7 and not available in Windows Vista or XP.
There have been reports that after upgrading to Windows 7, users received this message, even if they had a new battery installed! This article may interest users who are receiving this message on their LG laptops.

If, after you upgrade to Windows 7 on certain LG notebooks, the Windows Battery Meter displays the following warning message:

Consider replacing your battery

and this warning is displayed even if a new battery is inserted into the laptop, then a BIOS update may help you.

This problem occurs because of a code defect in the system firmware (BIOS) of some LG notebooks. These include the R500 family of notebooks.

The Advanced Configuration and Power Interface (ACPI) firmware does not correctly initialize and report the Design Capacity field of the static battery information structure that is retrieved by using the _BIF method. Therefore, the Design Capacity that is reported to Windows may be much larger than the Last Full Charge capacity that is also reported in the static battery information structure.

The Windows Battery Meter divides the Last Full Charge capacity by the Design Capacity to determine battery health. The Windows Battery Meter displays the “Consider replacing your battery” message when the Last Full Charge Capacity is less than 40% of the Design Capacity. When this issue occurs, the Design Capacity is reported as much larger than Last Full Charge capacity. Therefore, the “Consider replacing your battery” message is always shown.

To resolve this problem, contact the computer manufacturer to obtain a BIOS update for your computer. For more information & links, visit KB981200

Sleep, Hibernation & Hybrid sleep in Windows 7

Sleep is a power-saving state that allows a computer to quickly resume full-power operation (typically within several seconds) when you want to start working again.
Putting your computer into the sleep state is like pausing a DVD player; the computer immediately stops what it’s doing and is ready to start again when you want to resume working.

Hibernation is a power-saving state designed primarily for laptops.

While sleep puts your work and settings in memory and draws a small amount of power, hibernation puts your open documents and programs on your hard disk, and then turns off your computer. Of all the power-saving states in Windows, hibernation uses the least amount of power. On a laptop, use hibernation when you know that you won’t use your laptop for an extended period and won’t have an opportunity to charge the battery during that time.

Hybrid sleep is designed primarily for desktop computers. Hybrid sleep is a combination of sleep and hibernate; it puts any open documents and programs in memory and on your hard disk, and then puts your computer into a low-power state so that you can quickly resume your work. That way, if a power failure occurs, Windows can restore your work from your hard disk. When hybrid sleep is turned on, putting your computer into sleep automatically puts your computer into hybrid sleep. Hybrid sleep is typically turned on by default on desktop computers.
