'Battery Alert' appears before the 'press 'ESC' key for Start-up menu.', however, ' Cooling Fan Alert' appears after 'press 'ESC' key for Start-up menu.'

Thank you so much indeed,

No two computer manufacture's or even the same manufacture but a different model number may have the same BIOS options  (Intel CPU vs AMD CPU)

Could you please be a little bit clearer?

Firstly:

You meant that no two computer manufacture's BIOS or even the same manufacture have the same BIOS options. However,   a different model number may have the same BIOS options  (Intel CPU vs AMD CPU).

My laptop is HP Pavilion dv6 with this Product number: LM610EA#A2N. So, you mean if there is another HP Pavilion dv6 with another model/product number, then BIOS may have different options which can include  'Switchable Graphics mode '

Secondly **:**The BIOS vendor whose screen shot is above is **insyde H20,**and having the option 'Switchable Graphics mode 'Fixed/Dynamic' . Also, My BIOS vendor is also  **insyde H20 AY44 7578,**but it doesn't have this  Switchable Graphics mode 'Fixed/Dynamic'. It also lacks many other options.

You would not be able to.

Firstly: If the the internal/Intel GPU is set in  BIOS to be disable and just use the HD6770, I would not be able to  switch between the 'power-saving GPU, and high-performance GPU? Then, what benefits are there from having two GPU(internal GPU and discrete GPU). I noticed that the Internal GPU is got selected/active automatically once laptop got working only on the battery. 

Secondly: When you said 'You must set the BIOS to disable the internal/Intel GPU and just use the HD6770., you meant that with changing the Switchable Graphics mode to fixed/dynamic? Or  setting the BIOS to disable the internal/Intel GPU is different option other than this one which is below

**Thirdly:**If  setting the internal/Intel GPU to disable  in the BIOS and just use the HD6770 would help keep the CPU running cooler, I would change to only use Intel GPU 'power-saving GPU'  in  'Switchable Graphics' window below.

It should cover nearly the entire CPU / GPU after the heat sink is mounted on the CPU / GPU. What I do is apply 4 small dots of compound about halfway toward each corner of the CPU and one dot in the center and then mount the CPU.

I take extra effort on my computers to ensure nearly the entire surface (excepts the edges) of the CPU has thermal paste to ensure the best heat transfer from the CPU chip to the Heat sink / Fan assembly.

I have not covered the entire surface of the CPU and GPU with thermal compound for two reasons:

First one: There is a pad surrounded with the GPU(have you seen clearly my screen shot below?, I have pointed a arrow to the pad on GPU) Also,  I was told to not disturb the pad on the GPU with thermal compound. So, I have only covered the top/head of  the GPU with thermal compound. The CPU doesn't have pads, so I can cover the entire surface of it with thermal compound. 

The other one is: while dismantling my laptop for the first time after coming from the factory,  I only found that the old thermal compound was only put on the tops of CPU and GPU. It was not put on the entire surface of the CPU and GPU. So, the manufacturer didn't apply the thermal on the entire surface of CPU and GPU?

So, my questions are:

**Firstly:**Then, the desktop computers are much better than notebook computers since I noticed that almost all desktop computers have a graphics card integrated into motherboard, and another AGP slot to which an external  stand-alone graphics  card can be installed.

So, in desktop computers, if the integrated graphics card got defective, I have another AGP slot to which I can install  a stand-alone graphics card. 

Also, if external  graphics card was defective, then I can replace it without replacing the entire motherboard.

However,  I noticed that  laptops/notebooks(like mine) have a a discrete  graphics card integrated into motherboard, and graphics card integrated into CPU, then if the discrete graphics card integrated to motherboard got defective, then I would need to replace the whole motherboard. If the graphics card integrated into CPU got defective, I would replace the CPU.

Yes you would need to replace the motherboard, but there are some laptops that have removable graphics cards,

**Secondly: Could you please confirm this for me:**I noticed that there is a slight difference between desktop and notebooks.

In desktop computers, the internal graphics card is integrated into motherboard. However,  in notebooks(like mine), the internal graphics card(called:internal GPU) is integrated into  CPU.

However, In desktop computer, the external stand-alone graphics card is discrete which can be installed into the AGP slot/PCI express.

However, in notebooks(like mine), the discrete graphics card(called discrete GPU) is integrated into motherboard.

Again: there are some laptops that have removable graphics cards,

Firstly: You think that my BIOS does not have this option of Switchable Graphics mode as well, although my motherboard is Hewlett-Packard? This is most strangE . My BIOS lacks many options, although BIOS vendor is insyde H20 AY44 7578, and its motherboard is Hewlett-Packard? 

Note this screen shot was taken from an article of how to Switchable Graphics mode in BIOS at HP support website.

No two computer manufacture's or even the same manufacture but a different model number may have the same BIOS options  (Intel CPU vs AMD CPU)

Finally:(This is a little bit longer)

Although there is no option at all in my BIOS to set internal/Intel GPU to disable, I would like you to let me know:::

1- Why must I set that? If I had set that, then I could be no longer able to switch between graphics 'power-saving GPU, which is Intel GPU, and high-performance GPU, which is 'discrete GPU/HD6770.

I thought it would help keep the CPU running cooler.

2- I can switch between graphics (IGUP) and (DGPU) without seeing Switchable Graphics Mode in my BIOS

I am nearly sure that there is no option to set the Intel GPU to disable in my BIOS. I have tried that before(could you please take some time to look at my points below).

a) If that works for you then stick with it.

Firstly: if that option set the BIOS to disable the internal/Intel GPU and just use the HD6770. were available on my BIOS, and  If I set it, then then  how can I switch between the 'power-saving GPU, and high-performance GPU?

You would not be able to.

Secondly: When you said 'Intel, You must set the BIOS to disable the internal/Intel GPU and just use the HD6770., you meant that with  to change Switchable Graphics mode to fixed? Or this is difference option other than this one which is below

If you are still having problems I would replace the fan.

Firstly: By the way, you don't reply to me if cleaning the old fan with that paint thinner  would not let the fan function again as it is supposed? I will need to replace the fan with a new one even if the physically outside form of the old fan is still fine and good.

As said before 

I no longer have a new fan which can be compatible with my laptop, I have returned that new fan to the merchant. I have not used that new fan for two reasons, the first one I am NOT quite sure that that fan would be solve the problem with error 'the system has detected a cooling fan is not operating properly..', the other one is since it would be costing me a lot (about $50 for just a fan, in eBay.com, the Fan/heatsink assembly is sold for $30), so I have returned it to the merchant, although I have hardly found it in Yemen because  HP Pavilion Notebooks parts are not sold in Yemen.

I have been still asking you about this utility to know if my fan is working well or not since the error 'The system has detected a cooling fan is not operating properly' appears to me again, after I have blown the old fan with a compressed air and cleaned it with a paint thinner. Also, even I have cleaned the exterior vents in the heatskin/metal plate with the paint thinner and with  compressed air.  I.e. While dismantling my computer,  I thoroughly removed dust from all internal cooling components. Also, I ensured that wires from the system and CPU fans are connected to the motherboard securely.

It could be a defective fan speed sensor in the motherboard.

Yes, the fan blows air out, and the air is fairly warm, but the air blown out by fan is not very quickely.  The fan is blowing warm air from the computer. 

Note: I only applied new thermal compound on both of only the tops of CPU and GPU. I didn't cover the entire tops of CPU and GPU with new thermal compound since  I only found that the old thermal compound was only put on the tops of CPU and GPU. It is not put on the entire tops of CPU and GPU.

I take extra effort on my computers to ensure nearly the entire surface (excepts the edges) of the CPU has thermal paste to ensure the best heat transfer from the CPU chip to the Heat sink / Fan assembly.

Sorry, what was your final question?

Thanks a lot,

I have meant with that final question with  the list of questions below: I know there are quite a lot, but I hope you will find a convenient time for you.

1. My P 4 has a motherboardintegrated Graphics Card(onboard(Internal) VGA), Audio Card, and Network adapter. The motherboard manufacturer is Asrock(775i65G(REV: G/A 2.12) with integrated Graphics Card , and  AGP slot to which a removable graphics card can be installed.

Yes, apparently their are some motherboards with integrated graphics, Dell sold some P4 boards years ago. So you are correct, its just hat I have never seen any.

Thank you so much indeed,

So, as your previous comment '**Desktops do not have an integrated card on the motherboard, they are either integrated into the CPU like your laptop or the use the older style AGP or newer PCIe slots.'**was corrected by you now, I would return to my old questions you have ignored before.

 I know A 'graphics card' is the subsystem inside the PC that handles the video output. Can be a stand-alone card, or integrated into the CPU.

So, my questions are:

**Firstly:**Then, the desktop computers are much better than notebook computers since I noticed that almost all desktop computers have a graphics card integrated into motherboard, and another AGP slot to which an external  stand-alone graphics  card can be installed.

So, in desktop computers, if the integrated graphics card got defective, I have another AGP slot to which I can install  a stand-alone graphics card. 

Also, if external  graphics card was defective, then I can replace it without replacing the entire motherboard.

However,  I noticed that  laptops/notebooks(like mine) have a a discrete  graphics card integrated into motherboard, and graphics card integrated into CPU, then if the discrete graphics card integrated to motherboard got defective, then I would need to replace the whole motherboard. If the graphics card integrated into CPU got defective, I would replace the CPU.

**Secondly: Could you please confirm this for me:**I noticed that there is a slight difference between desktop and notebooks.

In desktop computers, the internal graphics card is integrated into motherboard. However,  in notebooks(like mine), the internal graphics card(called:internal GPU) is integrated into  CPU.

However, In desktop computer, the external stand-alone graphics card is discrete which can be installed into the AGP slot/PCI express.

However, in notebooks(like mine), the discrete graphics card(called discrete GPU) is integrated into motherboard.

b) Not all BIOS's include all possible settings, higher end motherboards usually have more options, entry level fewer option (based on the chipset and supported CPUs) and store bought system like Dell, HP, Acer the least number of settings the user has available and can change.
