if compute does not turn on then you might want to make sure ever thing is plug in ...

if ever thing is pluged in and and still does not turn on this might be the power supply has gone bad ...

What was the last thing you did on your computer before this happened?
Did you change any system settings in the BIOS?
Did you add new software? or update any software or drivers?
Did you add any new hardware?
Is your system BIOS infected with a virus?
Because it appears that your PC is hanging up during the Power-On-Self-Test [POST]

Here's what happens; when the power is turned on, the computer BIOS [Basic Input/Output System] runs a POST (Power-On Self-Test). It is a diagnostic testing sequence that the computer runs to determine if the hardware [like the mouse, keyboard, hard drive, etc.] is working properly.

If the necessary hardware is detected and found to be operating properly, the computer begins to boot; If the hardware is not detected or is not operating properly, the BIOS issues an error message.

The error message may be a text on the display screen and/or a series of coded beeps, depending on the nature of the problem.

The series or pattern of beeps may vary...they may be in a number of long or short beeps or a mixture of long and short beeps, or even one long continuous beep, depending on what type of BIOS is installed.

Since POST runs before the computer's video card is activated or the integrated graphic chip on the main board, it may not be possible to progress to the display screen.

So if an error is detected during the POST it will halt the boot process because the hardware is essential for the computer's functions.

How many beeps do you hear during the initial POST?

You may have a burned out video chip/card; or corrupt drivers; or even an IRQ [Interrupt Request] conflict.

Computer POST and beep codes
The computer power on self test (POST) will test your computer to make sure it can boot properly(test hardware and sys requirements), once it does the computer will then finish the boot process. Normally, if your computer passes the POST test it will beep once or possibly twice. If the computer fails the POST then it will either not beep at all or generate a beep code.

The beep code you receive can indicate what may be wrong with your computer. The beep codes vary depending on your motherboard BIOS manufacturer(AMI, Award, Phoenix). You can find what BIOS you are using by paying attention to the BIOS screen when your computer boots up. It should tell you what brand BIOS.

You can usually find the meaning of your beep code by doing a simple google search i.e "phoenix beep codes". Below, I have provided links to sites which go over beep codes and their respective meaning.

AMI BIOS Beep Codes
Award BIOS Beep Codes
Phoenix BIOS Beep Codes

No boot - short beep, long beep (it is not a memory problem)


When your computer boots up, the Basic Input-Output System (BIOS) performs an all-systems Power On Self-Test (POST).
The POST tests your computer's most important components, including the motherboard itself, the system's memory and the video card.
If the computer deviates from its standard beep, it may indicate a very serious problem with your computer, or it may simply indicate that you need to replace a system fan or a memory stick. BIOS beep codes vary according to manufacturer.

Start your computer.
Pay attention to the number of beeps and the length of the beeps.
There are short and long beeps.
Write down your observations.
Write down the BIOS type if this information is on your screen.
Consult your computer documentation if you don't know what type of motherboard you have.
Visit your computer manufacturer's support website for your computer model if you purchased a pre-built machine.


Look up your BIOS manufacturer (AMI, Award and Phoenix, for example) at a BIOS beep code website such as 5StarSupport, PC Hell or PC Guide (see Below).
Match the your computer's beep code with the beep code listing for your BIOS manufacturer.

Operating systems doesn't boot (BIOS beep codes)?


Do you have video going to your monitor? If not the beeps mean you have a bad memory stick in there. If you have video the beeps are the bios telling you that its not set right. More than likely you have it set to run too fast. Go into your bios find where the processor speed is located and choose a lower freq. rate. Its probably set too high for the memory you have.

Disconnect the drive and try to boot to the BIOS (usually with F1, F2 or Delete key). If that doesn't work, try removing all cards from the computer (except a video card if the video port is not on the motherboard). If you can boot this way, try inserting back any removed cards to see what hangs it. Do you hear any beeps when the computer is booting (beep codes)?

My dv6-1247 cl when i turn on the power it beep 8 times and the screen does not come on help


Yu will need to determine which BIOS you have a see below
The computer beeps several times
If you hear several beeps from the PC speaker, it means that the computer failed its power-on self test (POST) because a problem was detected. The POST is a procedure that tests several components such as power, BIOS, CPU, memory, and video. Only if all those tests pass, the computer will then allow the operating system to load. But if one or more of these tests fail, beeps indicate a problem and the boot process is halted. These errors are a little more difficult to troubleshoot.
To diagnose the problem, listen to the beeps carefully and write down the sequence. Is it one long beep? Is it several short beeps? How many? Once you have the beep sequence documented, you need to find out what it means. What BIOS do you have? When you first turn on the PC, look at the top of the first screen to find out. Common BIOS types are Award, Phoenix, and AMI.
Award:
1-2-2 Indicates a video error has occurred and the BIOS cannot initialize the video screen to display any additional information Any other beeps Most likely a RAM problemYou can find more detailed information about Award error messages on Award's web site.
Phoenix:
1-2-2 Indicates a video error has occurred and the BIOS cannot initialize the video screen to display any additional information 1-2-2-3 BIOS ROM Checksum 1-3-1-1 Test DRAM Refresh 1-3-1-3 Test Keyboard Controller 1-3-4-1 RAM Failure 1-3-4-3 RAM Failure 2-1-2-3 Check ROM Copyright Notice 2-2-3-1 Test for unexpected interrupts 1-3-4-3 RAM FailureYou can find more detailed information about Phoenix error messages on Phoenix's web site.
AMI:
1 beep Refresh failure 2 beeps Parity error 3 beeps Base 64K memory failure 4 beeps Timer not operational 5 beeps Processor error 6 beeps 8042 - gate A20 failure 7 beeps Processor exception interrupt error 8 beeps Display memory read/write failure 9 beeps ROM checksum error 10 beeps CMOS shutdown register read/write error 11 beeps Cache memory badYou can find more detailed information about AMI error messages on AMI's web site.
If you get beep errors, you should try to think what happened right before they started. Did you add a new piece of hardware? If so, it might be faulty or not installed right. Remove it, then try again. If everything is fine without the hardware, try to reinstall and configure the hardware again. If that does not help, try exchanging it and see if that corrects the problem. If the error persists, narrow it down systematically. Remove everything but the CPU, memory, keyboard, and video card, then boot again. Does the error still occur? If not, then add one piece of hardware and try again. Repeat until one new component causes the error and you now know who the culprit is. If yes, then reseat your CPU, memory and video card and try again. If the error still happens, try replacing the CPU, video card and memory one by one to see if one of them is the troublemaker. If that does not help, you could have a bad motherboard. Check the motherboard carefully for any signs of damage. Also check for shorts, a metallic object could have found its way onto the motherboard, or the motherboard is not installed correctly and touches the case somewhere.

Regarding with problem basically some part their failed. You need to check the RAM and HDD. Reset the CMOS battery remove the CMOS jamper with in 5 seconds and put it back. If you loss the first try you also recovery, to recover load the windows CD and boot up repair the windows until it is done. Good luck!

Won't pass startup bios / screen


Make a note of the number of beeps and whether they are long or short. Put the old video card back in the machine. Go online and do a search for "bios beep codes", check what you wrote down and see what the problem was. It was probably a video error. Perhaps you should install the video drivers for your new card before you install it, that way it might avoid the error on startup.

PC boots up, but no display and hard drive does not seem to spin


Actually you do want to hear one beep.
This is POST. Power On Self Test.
No display is a video problem. Swap the card for a known good video card. You should be able to get into the BIOS with that. Presario’s are quit.
While in the BIOS see if the HDD is shown. It doesn’t hurt to check the connection inside. Please keep yourself grounded when inside the PC. For the Compaq Presario S4020WM site go here:
