Question about Compaq PC Desktops

When trying to power up my Compaq nx6325 laptop, I only see the power light flash four times and then nothing happens. I have tried a second power source with the same effect. Any ideas please?

    Have you tried either power source with the battery removed from the system. The charge controller could possibly be bad telling it "empty" no matter what.

    If it turns on without battery, seal the battery in a freezer bag with no moisture and as much air squeezed out as possible for about 4 hours. then try putting it in and see what happens (just make sure no moisture reaches the battery. Lithium explodes with water contact)

The biggest mistake people do is not sysle the battery. A laptop cannot be left on, and plugged in all the time like a desktop. Turn it off if not in use and when using run the battery all the way down every so often. U may have to buy a new battery, so keep these things in mind. Also, ventilation is very important. Though it is called a laptop, soft surfaces inhibatit the cooling systems ability to keep it cool. The more powerful the laptop the hotter it gets. Heat will shorten the life of all the devices of a laptop including the battery.
Good luck

HP xw6200 Workstation - Diagnostic LED Code: Four Flashes ISSUE: When the workstation is powered on, the front LED might flash red four times, once per second, followed by a two second pause.

    1. Disconnect AC power.
    2. Remove all internal power supply cables from the system board.

Hello, When I power ON the desktop, It flashes a green light then after 1 second will start beeping with a red light. it beeps four times then pauses then beeps again for about twenty...


This issue might happen due to RAM.

To resolve this issue:
Turn of the power supply for your desktop.
Please remove the side case on your tower(CPU).
find the RAM slot and remove the RAM from the Slot.
Clean the RAM terminals with the help of cloth or Eraser.
After cleaning place the RAM on RAM slot.
Now try to turn ON the PC desktop. If it is working thats fine or else you need to replace another RAM to check.

Please refer the below figure to find the RAM Slot and the lock to remove the RAM.

Compaq Presario 5000 won't turn on


hi,
The machine is getting the power but no display.This seems a RAM or motherboard issue.
1.Press and release NUM Lock after turning on and if it is responding this is a RAM issue and if not then the mainboard issue but before all refix the RAM once.
Thank You.

Booting up


one light is for hardrive activity , the other is to show the power is on.. the flashing one is most likely the power light as most computers will tell you when thier ill....the beeping is an error code and should be in some pattern EG: Power LED blinks red twice, once a second, followed by a two second pause. Or something like that. Take note of the pattern and repost it here, then we can give you a specific area to look at.

Red light flashing on power button


Sounds like the hard drive has had a failure, you need to get a replacement one, and reinstall it, along with the opperating system, and any other programs that were on the old one.

Presario 6350CA won't boot


I don't know that I'm going to be a great deal of help, but here is the link to the support site for you Presario:

http://h10025.www1.hp.com/ewfrf/wc/product?product=390426&lc=en&cc=us&dlc=en&lang=en&cc=us

Here's a link to another page on the Compaq site that specifically talks about power supply problems:

http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph06788&lc=en&cc=us&dlc=en&product=390426&lang=en#N514

They discuss a flashing power led on this site, but I believe they are referring to an led on the power supply itself. Perhaps the led on the keyboard and the led on the power supply are both flashing...

Good luck. I hope this helps.
