After BIOS update, fan noise is reduced significantly.

Still below problems I am facing,

1. Laptop eats too much battery when in sleep mode.

2. Battery goes from is 5%  to 0% in a minute.

What can I do to solve these problems.

Thank you for posting back. 

Glad to hear that the fan noise issue is resolved. However still your experiencing issue with the battery performance.
The performance and capacity of laptop batteries naturally decrease over time.

Let's quickly diagnose the battery:

Use the following steps to open the Component Tests menu.

1. Hold the power button for at least five seconds to turn off the computer.
2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.
3. On the main menu, click Component Tests.
4. The Component Tests menu displays. Your Component Tests menu might be different, depending on the components installed on your computer.
5. To run both tests simultaneously, in the Component Tests menu, click Power Source, and then click Run once. Each component can also be tested individually.
6. In the Component Tests menu, click Power, and then click Battery.
7. Click Run once. The Battery Test begins.
8. When the battery test is complete, the results are displayed on the screen. For additional battery information, click Battery Details.

If the test passes, continue with these steps:

1. Go to Start, search for Device Manager, and open this result.

2. Expand batteries.

3. Right-click on the ACPI option (usually the 2nd option) and select delete or uninstall. Follow the prompts.

4. Shut down the computer. 

5. Disconnect the charger.

6. Remove the battery.

7. Hold down the power button for 1 minute.

8. Insert the battery only.

9. Attempt to turn the battery on.
