A way that I seem to know works well for setting BIOS problems back to default is to pull the CMOS battery. Wait 5 minutes or so, then put it back in and try booting.

Yes there is, on some motherboards, you must open the case and physically move a jumper over and back to clear CMOS. JMOS or CLRCMOS are some of the most common wording to look for when looking on your motherboard for the jumper I am speaking about. The quickest way to find the jumper is to look in the motherboard book that came with your motherboard unless you bought a OEM NAMEBRAND computer...which will not have a motherboard book. but one things for sure there will be the jumper somewhere on the motherboard. Now, on some motherboards such as the one I have there is a CMOS clear switch that is outside the back of the computer for easy resetting of the bios to defaults, however, most motherboards do not have this function.

ALWAYS have the system power off when performing these steps...

I have an hp pavilion dv5. When I power it on the computer starts up but the monitor doesn't come on. And then it does this series of beeps. Beep beep beep. It does that series 5 times


Before you begin
Check the following items before using the steps in this document:
•If you have a flat panel LCD monitor, unplug the monitor power cable, wait about 30 seconds, reconnect the cable and then turn on the monitor. This resets the electronics on the monitor.
•Make sure the monitor has power - the light on the monitor is on. If the light on the monitor is off, the monitor does not have power. Connect it to a different power outlet.
•If the monitor has a detachable video cable, obtain a second monitor cable for testing purposes in case the cable is bad.
•Disconnect all connected devices except the mouse, keyboard and monitor. This includes thumb drives and camera-type memory cards from card reader slots.
With the devices disconnected, restart the computer. If the computer starts and the monitor now displays a picture, a device is preventing the computer from starting. Update the BIOS to resolve this issue.
Step 1: Connect the computer to another monitor
Connect another monitor to the computer to determine which device has the problem (the monitor or the computer). This step is very important to help you determine if the problem is coming from the computer or the monitor. If necessary, temporarily connect the computer to a friends monitor for troubleshooting purposes.
After the monitor is connected, turn on the computer and the monitor. What happens?
•If the newly attached monitor does not display anything , disconnect the cable and continue at Step 2: Is the video connection damaged?
•If the newly attached monitor displays the first startup screen(s) but then goes black, there is a problem with Windows starting. Skip to step 5 .
•If the new monitor works , the original monitor or its cables are faulty. Do the following:
1.Replace the monitor power cable.
1.Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
1.Replace the video cable.
Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
1.If the monitor does not work after replacing the cables, replace or service the monitor.
Step 2: Is the video connection damaged?
Inspect the video cable and video connectors for damage. Check for sharp bends or breaks in the cable and bent or broken pins at the connectors. With the monitor and computer off, try to straighten bent pins with a small metal tube, like the tip of an empty mechanical pencil or the tip of a retracted pen.
Figure 1: Video connector
If you had to straighten any pins, reconnect the monitor making sure that the video cable is firmly connected and then turn on the computer and monitor. If the display is still blank, continue to the next step.
Step 3: Resetting and updating the BIOS
You can use these steps even though you will not be able to see anything on the monitor.
In case an item was changed in the BIOS, such as the primary display device setting, use the following steps to reset the BIOS back to its default configuration:
1.Turn on the computer and repeatedly press one of the following keyboard keys. Press the key about once every second for 5 seconds after turning the computer on.
◦For HP and Compaq computers that came with Windows 7 and Vista, press F10 .
◦For HP and Compaq computers that came with Windows XP, press F1 .
◦For Compaq Presario desktop computers built prior to 2002, press F10 .
1.Wait another 5 seconds.
1.Press the F5 key. This restores the default settings of the BIOS.
1.Press the Enter key. This accepts the changes.
1.Press the F10 key. This saves the changes.
1.Press the Enter key. This saves the changes and exits from the BIOS.
1.The monitor should display the first screens received from the computer (the logo screens). If not, find and download the latest BIOS update if one is available for your computer.
1.If a BIOS update was not available or the monitor is still blank, continue to the next step.

Tip

Computer beeps


If you try to power on your computer and nothing happens but a bunch of beeps there is something you can do. The beeps actually mean something. To make sure you can hear the beeps check in the bios options. If there is an option for a silent boot you won't hear any beeps. If you hear one beep every time your computer starts then you don't have to worry about this.

If you want to check this setting refer to my other tip on how to enter bios and change boot settings.

If you try to boot your computer and nothing shows up on your monitor do these steps first.
1-Check all your cables in the back of the computer.
2-check your power source and power cord to the monitor
3-try another monitor if possible
4-If on a power bar try to turn off the power bar and reset the breaker

If you try to boot your computer and nothing happens and you hear beeps look at this website. The beeps you hear are actually telling you what is wrong. Look at the website by clocking on the link below and click on the computer beep codes link. If you want to scroll down past the link it will show you bios codes to enter the bios in your computer

Monitor won't come on..just blinks..


Hi,

a common way to solve this is to put the BIOS into its defaults...
i.e, loading the BIOS with default settings..

to do this you need to open the case of your CPU then, on the motherboard there is a small battery called CMOS battery...
take it out and after a minute or so put it back...

in this one minute, the BIOS will get reset to its default settings...

you should now be able to work........

If this sol. helps please give a vote....

try resetting your bios.. reset it to system defaults.. check all connections properly.. pc to monitor..etc etc..
if you mean no error code by "no bios beeps" then it's okay..
if you mean even the regular single beep after post is not heard than chances are high that your video card has some problem.

How long are the beeps? If they are shortish then it suggests that the ram on your motherboard isnt working properly. Try removing it and reseating it. Make sure all the power is turned off before doing this.

Also there is a jumper located near the bios battery for resetting the bios. Move that to the clear position then back again after a minuter or so. That will put it back to default setting.

How did the problem start? Had you been adjusting anything in the bios at all?
