For VLOGEEK:
Windows 7 shows the red cross on the battery icon when the battery's last full charge is below 40%. I had faced the similar problem and when i found a solution (not applicable on everyone), then i posted it here whereas it had helped alot of people
removing the same issue. Its not a lie by Windows 7 regarding the CONSIDER REPLACING BATTERY message as this message comes as the above issue occurs. Sometimes, when people use their laptops without removing the charging pin (even if the battery is fully charged),
then the battery cells starts becoming dry due to non-usage of battery. After a time, when you use the laptop on battery and empty the battery's charge, the dry cells does not wake up and when you charge it again, it does not shows full charge which tends
to show this message ( if the battery's last full charge is less than 40%).
For poojanegi:
search for command prompt in start>accessories>command prompt.
Open the command prompt by running it with administrator priviliges by right clicking on command prompt and choosing the "RUN AS ADMINISTRATOR" option.
When the command prompt got opened, please remember the directory/folder where is the command prompt's cursor is blinking because the report will be saved in the same directory/folder.
- In command prompt, type "powercfg -energy"
- It will take 60 seconds to analyze the battery and power levels. When it is completed, then open the same directory through Explorer which was shown in command prompt.
- the file name will be saved as "energy-report.html". Open it
- Scroll down and find the battery health/level where DESIGN CAPACITY and LAST FULL CHARGE will be written. Take percentage of last full charge by dividing the last full charge upon design capacity into 100.
- IF your battery level is less than 40%, then start perform the below steps:
a. charge your battery until it is fully charged.
b. when it is fully charged, remove the charging pin and start using the laptop on battery.
c. Use the laptop on battery until and unless it becomes off due to low battery power.
Note: When the laptop becomes off, on it again and start it until it turns off again. Repeat the process until and unless the battery does not shows up any power.
d. After the above steps, start charging the laptop battery's again.
e. REPEAT THE PROCESS FROM B TO D FOR 7 TO 8 TIMES.
f. after repeating the process for 7 to 8 times, check the last full charge by repeating the process from 1 to 4.
If your battery has life, it will DEFINITELY INCREASE the Last full charge. If you find that it is increasing, try repeating all above mentioned steps until it crosses the last full charge above than 40%.
For Sana Hashemi: My laptop was also 1 year old. I Performed these steps and was able to make the last full charge from 21% to 73% :)..Don't lose hope is the model of the story.
