Dell Latitude E6400 battery problem

Hello , thanks for the answer but my bios is the last one A32 . If reflash whit same BIOS can resolve a problem ?

Hi didodi,

Still you can go ahead and flash BIOS on the computer with the same version.

Note:

1. During BIOS update verify that the computer is connected to an AC Adapter.
2. Disconnect any third party peripherals connected to the computer before performing BIOS update.
3. Do not turn off the computer during the BIOS update.
4. Do not restart the computer during the BIOS update.

Also, let me know the diagnostics results on battery.

Awaiting your response!

Hello , after flash my bios whit A31 bucouse A32 not run , the same test is same result : 

Hi didodi,

The following factors affect battery performance:

• Processor speed - Enabling features such as Intel SpeedStep® or AMD PowerNow!™ extends battery life by automatically adjusting the processor speed to meet system demands. These features are typically enabled by default on computers that support them.
• CD, DVD, CD-RW and hard drive access frequency - Moving files and programs directly to the hard drive, when possible, reduces the number of devices requiring battery power. Adding more memory can also help by reducing the need to use a swap file on the hard drive.
• Programs - Running only the programs that are necessary reduces demands on the system processor and memory. Programs that cause intensive use of the processor and drives (such as playing a DVD movie or 3D games) can more than halve the amount of time that the computer can be used on battery power.
• LCD brightness - Lowering the brightness of the LCD screen reduces the amount of power required by the screen. To adjust the brightness of the LCD screen, press + to increase the brightness or + to decrease the brightness on the LCD display panel.
• Backlit keyboard - Turning off or halfing the brightness of your backlit keyboard can conserve battery power for when you are using your computer. Typically to adjust the brightness of the backlit keyboard, press + to cycle through two brightness settings and the off setting.
• Power management - Set the computer to enter suspend or hibernate when idle to conserve battery power when the computer is not being used.
• Battery age - A battery's average life expectancy is 1 year. After this time, it is normal to experience a decrease in battery life.
• Battery age/life is in no way shortened, when the portable computer is directly connected to AC Power (power outlet) and continuously used for long period of time. The reason is that the system motherboard automatically stops power flow to battery, as soon the battery is fully charged.

We need to replace the battery on the computer.The Battery would have 1 year of warranty from the date of purchase of battery.
