No display, beeps

Hi,
Try running the diagnostics on the computer. You may need to repeat some of the steps that you have already done to initiate the same.

1. Remove the battery and the Ac adapter from the system
2. Press the power button for 10 seconds
3. Reinsert the battery and connect the Ac adapter
4. While holding down the FN key on the keyboard press the power button.

If the system beeps in a series on 3-3-3 or 3-3-4 the system is ok and there could be a problem with the screen.

If the system beeps in some other code . revert to the post and we would let you know where the problem is .
Thanks for using fixya

It should at least beep. Those beeps are diagnostic codes. Listen to the beeps and google 'bios error beep codes'. If it doesn't beep, the motherboard must be replaced.

I have had this problem and never quite got to the bottom of it. Because it doesn't get too far when in starts I think it is memory related or bios. Opening and closing the case can reset the bios on some computers so check this setting in bios, to stop it happening try turning of sleep or standby function in bios.

Open it up again and find the wire you blew off.

That beeping noise may be due to over heating.
Most machines today have a temperature setting that will turn the machine off once the temperature reaches a certain point.
Safety feature to avoid damaging your cpu and components.
The shut down and restarting allows the CPU to cool down briefly.
Thus allowing you to start the machine again. Usually it will shut down again once the temperature threshold is again reached.
Good test is let the machine sit for 30 min. If it immediately starts up and shuts down a few minutes later. Heat build is usually the problem.

Typically this is due to heat sink or Fan on the computer CPU.
Check to be sure both are connected to the CPU and functioning.
If you have a fan on top of the heat sink above the CPU. Make sure it is working correctly. Dust build up over time will eventually kill the fan bearings or reduce airflow. Heat sink can and will become clogged with dust also. Replacement fans are easy to find. Heat sinks are even easier to clean.
Depending on your machine and CPU position replacing the fan can be a challenge. But can be done in a few minutes with minimum tools.

Each bios has different post codes and it is difficult to tell what is happening with out knowing the bios of your particular machine. Listen for the beeps and check your computer manual.
You can also google for this. Here is a web site that lists a few bios P.O.S.T codes.

Once you know the beep sequence you can look it up. Usually points to the problem and you can go from there.

Good luck!

plz try by resiting the ram

blow out dirts on bord, then you pack the board to avoid any bridging with the cassing

1 short beep
Normal POST - system is ok 2 short beeps POST Error - error code shown on screen No beep Power supply or system board problem Continuous beep Power supply, system board, or keyboard problem Repeating short beeps Power supply or system board problem 1 long, 1 short beep System board problem 1 long, 2 short beeps Display adapter problem (MDA, CGA) 1 long, 3 short beeps Enhanced Graphics Adapter (EGA) 3 long beeps 3270 keyboard card

clean your cpu and put new heatsink compount
clean ram contact using student eraser
if you have postcard so you can judge problem

you may be knowing there are many types of beeps which made as standard for all pc ...
if the pc beeps for 30 seconds and then starts means there is no input device connected ...(here the standard input device is keyboard)
so c the keyboard is connected properly or not try reconnecting it...
and about the display when sometimes computer makes beeping sound the screen is not displayed ... after connecting that just try is it working or not.. if problem persists then just check the cables of the monitor too... try reconnecting them also.....
