HP Compaq Presario SR1430NX Powering On Issues...HELP!!??!??


If the power supply is "Fine" then it has to be your motherboard. Look for the capacitors around the board. They should have either a dished or flat top. If any are domed or have a powdery substance on them, they will need replacing. Or if you don't want to do this, replace the board.

It had been quite a while since I turn on my compaq presario 7204APr. And when it turned it on, there is no image appear on my monitor screen. How can I fix it?


Desktop PCs have separate power buttons for the monitor and the desktop component.
1. Make sure both items are turned on.
2. Make sure the cable from the Computer to the monitor is connected securely.
3. Are there lights on the monitor? Are they Green?
If they are amber the connection is not solid or the Video Card is bad.
Are there lights on the desktop PC? Are they blinking? If so the PC is working and the video is not. Check the connections and monitor power.

4. When you turn on the PC do you hear noise? If yes, the PC is working.
Beeps will sound if the video, memory or keyboard is not working.

After you check these things, reply to let us know if it is working or not.

My monitor has kicked into sleep mode and won't "wake up".


Unplug all the Cables from Compaq Presario 5103 CL and leave the Keyboard, mouse and monitor cable pluged in.

Now make sure the power cable of the monitor should be pluged in and the power cable of the tower should be pluged in.

Now to check if the montor is fine just unplug the video cable only which will show no input signal on the screen. If it shows this signal the monitor is fine. Plug back in the video cable.

If the monitor is going to sleep mode it might be possible that the old computer ( Compaq Presario 5103 CL ) is in stand by mode. hit any key on the keyboard and it should come back .

If it is not in the stand by mode then do one thing. Check the same monitor with the new computer. If it is working. Perfect ..!

Do one thing now ..!

Unplug all the cables from your old system and then press the power button for 30 sec and let it go. Now plug the keyboard, mouse and the monitor try again.
If it works Perfect. If not ..!

Then you need to open the tower and check on the processor FAN is it running..? If its not running you will not get the display as the fan is responsible for the display on the screen. Otherwise...!

Check the Tower possibly the Tower is not getting the power.

Try these steps and let me know If it works

Presario 6000 desktop wont power up after transporting. Opened cover & I have loose wires that may be the problem. The loose wires are labeled p9 &p7.


Unfortunately, I do not know P9 and P7. Can you tell me if they are multiple colored wires going into a header/connector? If they are single wires or thin wires you may be able to look at your header of wires which connect the pwr button, rst switch, power led, speaker ( 4 pin thin connector ) if p9 and p7 came off here they could be your power switch.

Presario 2190us change internal battery, not the pull out battery on the side


Turn the laptop over. There will be one or more access covers retained by screws. Remove them. Somewhere on the motherboard you will see the battery. It will either be attached by 2 wires and the battery insulated, in which case you pop the wires off the board to replace the pattery. Or it will be directly mounted to the board. This one will be about the size of a quarter. it's basically a watch battery. The is a small clip that releases it from the holder. Press it and flip the battery out.

Turn the computer on no matter which button i push


You may have a defective keyboard. A defective keyboard will stop the boot up process. Try another keyboard and see if that fixes your problem.

Compaq 5000 series JBL speakers


Hi Shockme17, sorry for late response I have been away. Gently remove the frame holding the material speaker cover by pulling it off from the top (the material speaker cover is just a push fit on the main body of the amp/speaker). Don't use any implement, you may damage the cover. Once you have worked the cover off iy will expose 4 screws holding the unit together. Remove those & the unit splits into two parts. JeffuH
