the HP 550 laptop lost the option of BIOS, there is no menu

Specs: Windows 7
Indeed, the HP 550 laptop lost the option of BIOS, there is no menu where you can reset the data of the day, date and time as it loses this data, and each time you turn, you have to reconfigure it again, but since the option to display Windows 7 and not from the Bios. Change the RTC battery but remains the same. On the internet recorded this problem in different brands since 2004 and perhaps before, and I am confused by the amount of information given from the RTC change to change the motherboard, it may be a bug in it.
In the technical manual of the device appears as an option F10 to enter the Bios, but in my case, F10 does nothing more than what I press repeatedly.
With the menu option F2 to enter checking, among other things, memory, and hhdd, and tell him that in these menus is an option to configure the BIOS, but color appears paler, grayish, faded, discolored, and displayed on the screen, below, required to push F10, but does not occur at all. That's how the BIOS option deleted from the system.
I inform you that to change the RTC had to completely disassemble the HP.
I was informed that warmed a little more than time ago, and change the thermal paste, you clean the vent, and opened with the drill as 120 holes with the drill below the apparatus, where the video chip is going to to breathe a little better. It was a preventive maintenance.
But my headache is in the Bios.
Please friends, I ask if any of you have encountered this problem in the HP 550, or similar, and could fix the problem, give me a help, because I'm in a dead end, and I think change the motherboard would be far too expensive.
Thanks in advance, and good luck to you.

"I think change the motherboard would be far too expensive."

But that might be the only way to fix it.

Okay, may be that changing the motherboard to fix the problem bios.Pero, someone skilled in the art could bring here the cause or causes that can provoke this failure in computer equipment. So, would have a notion to try to prevent the failure.
Grateful for the answer he gave me pip22.
Thank you.

I believe that HP, in the interest of simplicity, have options to hide/display various F keys that would normally take you to the setup screen.

If I understand your problem, you are not seeing any option to enter the setup screens, is that correct?

edit
As soon as you press the start button start tapping the F9+F10+F12 (all at once) to get to the screen you want.

OtheHill friend, try all three keys at the same time, but nothing happens, and load windows, but I already reported in the first post, who had had access to the BIOS menu by pressing F2. But my question was different.
For as our friend said that pip22 to repair that error in the BIOS must change the motherboard, is, I wondered, that's what I fault the board, or circuit is damaged.
Because motherboard repair is possible, especially when you understand the nature of the fault and electronic components that are involved there.
Anyway, I gave the HP 550 notebook without overheating, and without losing the time and date, and the customer was satisfied.
I'm opening my notebook repair business and I am very grateful to the forum for helping me better understand the failure and its solution.
Soon, and good luck to all.

Hello again, and with bad news, because the owner of the HP 550 notebook came with the device to explain that now certain keys do not work. The following keys stopped working: F9, F10, F11, F12, O, L, and the point. ¿?
I thought this was a repair and filed, and perhaps the nightmare is beginning ercien.
One detail I submit, is that the keyboard worked perfectly until our friend suggested me to squeeze HotheHill F9, F10 and F12 the three, together. And I think the keyboard is locked. Or he blocked a field.
Please do not want to start re-arming and disarming the notebook without a clear first, or, causes of this failure on the keyboard.
I ask HoteHill to tell me if you ever happened on this.

That is OtheHill. I suggested using those three keys because that works on a Compaq laptop I have in front of me now.

If in fact depressing those three keys together caused some change in keyboard behavior, then using the same key strokes again should toggle you back to the original state.

I suggest you download the manual for that model. Read any propitiatory key stroke actions for that model.

The first link below is general. The second deals with the keyboard and touchpad. I also suggest trying an external keyboard to see if it is a defective keyboard.

If you are going to charge for your services you need to learn how to research this stuff yourself.
