WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Remove the memory modules from their slots. Take the opportunity to clean the slots on the motherboards and the memory module connectors. Use compressed air to blow dust away and clean contacts with a soft cloth. Do not use a metallic vacuum cleaner if it touches any component it may create a short and cause damage to the motherboard or other components. Do not use solvent that may attract dust and never poke things like cotton buds in to slots. lightly rub an alcohol (Methylated Spirits) on a cloth not to hard let the alcohol do the work on the copper gold or silver tabs and r Allow the pins to dry. They will air dry in a matter of minutes. If reseating the memory did not resolve the issue try swapping the location of the memory. If you have only one stick of memory in the computer try moving it to another slot and then boot the computer. Check the memory module and memory slot contacts. They are either copper tin or gold. The colour will tell you which they are. Mixing tin and gold can result in corrosion that prevents proper contact. Look for any sign of physical damage to the memory module, memory slots or the motherboard. Reseat the memory modules. You should hear an audible click when they are in place. Do not use too much force to reseat the memory module in to the slot this can cause damage to the module, slot or motherboard. The hardware that you are trying to access is damaged or failing.


The device drivers for the hardware are faulty or incompatible.
There is a connection problem such as a bad cable for internal hard drives
Test all power and data leads that attach to your hard drive IDE,SATA
the leads from your MOTHERBOARD TO THE HARD DRIVE make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty if its a flat 40pin ide this will be the first to fail Make sure all leads that are attached to your drives dvd\cd and floppy (If Applicable) have secure connections and are not faulty. or just replace them they could be faulty a computer needs power and data to travel through every working device and continue its cycle and have an end so any faulty leads will end up with a computer error

Hope this helps.

    what happens when you try to access bios During the boot process you will see on the screen to press a certain key to enter setup usually the Delete or F2 key Press and hold that key during the boot up process to enter BIOS using the arrow keys load failsafe defaults or load optimized defaults press escape then press f10 to save to cmos to restart

    Make sure the Ps 2 or the usb lead connections are secure (if applicable) Make sure the batteries have charge and are getting good contact (if applicable) Click start control panel keyboard hardware make sure you have the right keyboard selected or you might have uninstall the keyboard then restart your computer then reinstall it and its drivers Click start control panel administrative tools computer management device manager scroll to keyboard you might see a yellow question /exclamation mark ? ! or a red X right click update driver if your computer came with a motherboard disk the drivers could be on it.

  • Brian Sullivan
    Brian Sullivan Jan 16, 2013

    cmos batteries some motherboards there soldered in if you remove cmos battery leave it out for 30 sec should reset cmos if does not leave it out for 1 min is your computer posting making any beeps You may see strange error messages or hardware may not be recognized properly. Another symptom of a BIOS problem is the computer's RAM, normally counted during the POST, not being counted correctly or producing an error message during the count. The most common symptom of a BIOS corruption or crash is the BIOS simply refusing to POST.

What function key gives entry to cmos


BIOS is fixed program that starts up the computer. BIOS is initialized during start up of HP Compaq-6715B which sets the computer settings to be uploaded. BIOS enables the creation of a bootable diskette, CD, or USB key that can be used to locally restore or upgrade the System BIOS in the supported notebook models with a 68YTT Family ROM. Only insert the USB drive that will be used to format and create bootable BIOS upgraded USB media. However, you should remove all unused USB drives and flash drives from the notebook before. In order to ROM family and ROM date, press F10 on the target notebook during startup to run the setup utility.

The tips to get into the BIOS of HP Compaq-6715b are:

  • Press F2 for setup
  • Shows logo
  • Independent of OS
Press F2 for setup

BIOS often has a blue background, and uses the arrow keys, PageUp, PageDown and enter keys to change the settings. After you have got into or accessed the BIOS, you can change the boot order settings so that the floppy disk is checked first to see if it contains a bootable program. Usually a message will appear telling you how to enter the BIOS setup program as the computer starts up, such as Press F2 for Setup.
Shows logo

Your HP Compaq-6715b might be configured to show your computer's logo instead of important BIOS messages. In this case, you can press Esc or Tab while the logo screen is visible. If you are facing problems pressing the pause button in time, turn on your computer with your keyboard unplugged. In this situation you will receive a keyboard error, which helps you in pausing the startup process long enough for you to see the keys necessary to enter BIOS.
Independent of OS

The PCs with both PS/2 and USB connections are configured to only allow USB input after the POST. If you are using a USB keyboard, it could be impossible to access BIOS. You would need to connect an older PS/2 keyboard to your PC to access BIOS. The BIOS accessing is independent of any Operating System on your computer because the BIOS is part of your motherboard hardware.

Keys to use at boot time to access bios


It isn't keys, 3glarry, it is key.

It is either the F1 key, or the F2 key.
This key should be displayed when the Gateway logo comes up.
Gateway logo appears? Look quickly at the bottom of the screen.

Preferred method to enter BIOS Setup is this;
As SOON as you press the Power On button, start tapping on the appropriate key. Tap in 2 second intervals.

You may hear beeps. These are Stuck Key Error Code beeps.
You know they aren't real, because it is you that is doing it. Not a stuck key on the keyboard.

Why use this method?
Because the window of opportunity to enter the BIOS Setup utility, goes by F-A-S-T!

Now, may I ask what you are doing in the BIOS Setup utility? Post back in a Comment.

Regards,
joecoolvette

Reset the BIOS on a Compaq server 740 jumpers settings


Don,t do that insatead:
Entering the BIOS Setup menu Entering the BIOS Setup menu requires pressing a specific key at a specific time. If you fail to enter the Setup menu on your first try, repeat the following steps until you are successful:
  1. Close all applications that are currently running and restart the computer by clicking Start , Shut Down , Restart the Computer , and then OK .
  2. When the red Compaq logo or blue HP logo screen appears, press the F10 key on the keyboard to enter the Setup menu.

NOTE: An alternate to the above steps, especially if the logo screen disappears too quickly to enter BIOS, is to shut down (turn off) the computer. Wait 30 seconds, turn the power on and press F10 or F1 at the logo screen. Reloading the default settings Complete the following steps to reload the factory installed BIOS Setup settings:
  1. In the BIOS Setup utility, select the Exit tab.
  2. Select Load Setup Defaults .
  3. Select Save Changes and Exit (pressing F5 and the Enter key will also load the Setup Defaults).
  4. Press Esc and then Enter to exit Setup.

Keyboard is not working during boot up. So cant boot from a CD. What possibly could be the problem.


1. Always start tapping any key when you see logo of the manufacture like Dell, HP.
2. If it all does not work, Go to bios(It depends upon the manufacture, try F2 or F1 or Del at the startup) and make CD-ROM as the first boot device. Note:As soon as you see manufacturer logo start tapping, F2 or F1 or Del key to go to bios.
3. If you have a wireless keybord, try to use a wired keyboard.

hi,is your keyboard working at the bios try tapping F2 or del whatever the initial screen say to enter setup and see if your keyboard works there, this can happen if you are able to see the hp logo at start if you are not able to see the hp logo take out the keyboard and start the system see if you are able to see the hp logo and go beyond, if so first try to reseat the keyboard cable at the back of the system tower and then try and if it still doesn't work try by replacing the keyboard.

and if you are able to see the hp logo at start then start tapping the F8 key and it will send you to a menu where it will give you the option of safe mode, select safe mode and press enter and see if your keyboard works here, if it does work here
then what we can do is restore your system to a back date when your keyboard was working fine, doing a system restore will mean that the new installed programs and the configuration done will be lodt beyond the restore to date
