'Battery Alert' appears before the 'press 'ESC' key for Start-up menu'

Hi,

First of all: I know that I have been having a problem with my HP Laptop Battery, and with its cooling Fan.
However, I am now wondering what detected this error below as long as it was shown even before the notification saying 'the press 'ESC' key for Start-up menu.' Thus, if the BIOS detected that there was a problem with the HP Battery storage', then this error should have been listed after 'press 'ESC' key for Start-up menu.' was passed.

'HP Battery Alert:
The system has detected the storage capacity of the battery stated below to be very low. For optimal performance, this battery may need to be replaced.'


That alert lasted about 15 seconds, and then the 'press 'press 'ESC' key for Start-up menu.' is shown.

Next: This is error below showed me::
'The system didn't detect that a cooling fan is operating correctly'

I know that BIOS detected that a problem with 'Cooling Fan' since the Alert of error was shown after passing 'press 'ESC' key for Start-up menu.'


Any comments would be highly appreciated

Thanks a lot,
First of all, I log(enter/load) BIOS in my HP laptop by pressing the F10. Now, if I want to enter to the BIOS, I must wait until the error HP Battery Alert' disappears, then I press 'F10'.

Thus, the error 'HP Battery Alert:
The system has detected the storage capacity of the battery stated below to be very low. For optimal performance, this battery may need to be replaced.' was not detected by BIOS since it was shown before the ability of entering to the BIOS by pressing the F10 key(IF I wanted).

This error below"'The system didn't detect that a cooling fan is operating correctly' was detected by BIOS since it was shown after the ability of entering to the BIOS by pressing the F10 key(IF I wanted).


While your computer is loading, you will be seeing 'press 'ESC' Key to enter to start-up menu, which contains 'booting devices(F5), BIOS F10, and so on. I don't know if this message appears in all computer brands or not.

However, as long as entering to BIOS will be by pressing F10, and that error 'HP Battery Alert:
The system has detected the storage capacity of the battery stated below to be very low. For optimal performance, this battery may need to be replaced.' was shown before entering to the BIOS, then I don't think that error was detected by BIOS IF so, then this error should have been listed after the ability to entering to the BIOS 'press 'ESC' key for Start-up menu.' was passed.



I hope you understand me.

As mentioned, the message is from the BIOS. Traditionally the BIOS loads BEFORE any Operating System, lets the OS know about resources available for running the computer. As with one of my HPs, your battery is bad. Might try removing the battery and running on the AC adapter.

Is the time and date staying current/correct? If having to be reset at each bootup could be the CMOS battery on the motherboard has lost power, more difficult to change as many parts of the Notebook have to be removed to get to it.

The fan is another issue and if the CMOS battery has to be changed might as well do the fan at the same time.

I do not know where you got this preconception from, about messages from the BIOS must be after this or that and anything else must be from something else. That is wrong. The message you are getting is from the BIOS detecting the bad battery.

This message is coming from the BIOS's POST (Power-On Self-Test) that runs before anything is even displayed on the screen.

Power-on self-test - Wikipedia, the free encyclopedia

Thanks a lot,
I now must agree with you.
However, that message containing 'HP Battery Alert' raising another question which is: How could the BIOS realised that the my Battery is HP brand. Although my Notebook is an HP brand, I don't think each part of it was made by the HP company. (i.e. the BIOS of my notebook might be made by antoher company other than HP, thus how could BIOS realise that my battery is HP brand, and then showed me 'HP battery alert'.)

Furthermore, You mean with 'Power-On Self-Test' that it is an option in the BIOS which can be enabled, and disabled. If so, then If I had disabled the Power-On Self-Test, then I would be no longer seeing this error messages?

ALL BIOS in ALL Computers(Desktop, Notbook) first check, and detect the integrity of all the hardware components connected to the a computer, before OS loads.

No, you cannot turn off POST, at most you can switch to what is normally called Fast POST which skips some of the tests. The battery test is not one of those skipped test.

Could you let me know how to switch to what is normally called Fast POST which skips some of the tests. I really see my BIOS cannot be modifed by some options, except the editing 'device boot' can be edited.


Moreover, BIOS must check all hardware components plugged(connected) to a computer. On Desktop Computer with Intel P 3 processor, I really have have a problem with Disc optical, however, when run the computer, I didn't see the BIOS detected any errors,. Thus, I think that BIOS doesn't detect the integrity of all the hardware components connected to the a computer, before OS loads.
