    Me too!! I have the presario v3000, though. I was just online typing away, and all of a sudden it turned off and won't turn back on!! I'd only been on it for 20 minutes!! I've tried everything. Unplugging, replugging, holding the "on" button, etc...nothing!! I've had this computer for several years and never had this problem. PLEASE....ANYONE!!! I need to know what to do!! I have a lot of info on that thing!!

If the laptop posts: (power on self test) and you see stuff on the screen, no matter how short ,do the following:
if you have a bootable anti virus disc use it to check for any viruses , if not
try a recovery disc,
both will try to access the hard drive.
if they do not work,(nothing has changed) nothing comes on the screen.
laptop does not post:
remove the screw(s) holding the cover plate where the ram lives
remove the memory sticks, clean the gold edges with a pencil eraser both sides and re-insert them, (not an ink eraser as it will do damage)
swap them around if you have more than one,
if you only have one, borrow one from a friend or try the ram in your friends laptop ,if that's possible, or take the ram to your local pc shop and ask them to check it for you (they may or may not do that for you)
if you can establish that the ram is ok, and anti virus and recovery disc's do not work,then it is most likely, the motherboard has failed .
good luck with that and let me know how you get on.

Compac computer won't turn on and the power light blinks constantly what can i do to fix this problem


Does it beep? if it does, whats the beep pattern...ie long long short, or short short short

if nothing else, something is causing a short...check the usb ports (real common) the contacts break from wear and short out, have your power supply tested.

How to re-wire a Compaq Presario SR2150NX Case power Switch


The plastic front of your desktop computer is the Front Panel.

The area of contact pins on the motherboard, that the wires from the Front Panel go to, is the Front Panel header.

F_PANEL_1

The Front Panel header contains connections for the Power On switch, Power On LED light, HarDDrive activity LED light, and so on.

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00864922&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=3339274

(Look at the motherboard photo. The Front Panel header is at the bottom right. Scroll down for the motherboard illustration )

There are 9 contact pins.
4 across the Top row, and 5 across the Bottom row.

The four pins across the Top row are numbered EVEN.

From the Left side going towards the Right side;
Pins 2, 4, 6, and 8. There is NO pin 10, just a blank spot.

The five pins across the Bottom row are numbered ODD.
Pins 1, 3, 5, 7, and 9.

A) Pins 2 and 4 are for the Power On switch

B) Pins 6 and 8 are for the Power On LED

(LED is dim when the computer is on? Switch the wires around )

C) Pins 1 and 3 are for the HarDDrive activity LED

(LED is dim when the harddrive is operating? Switch the wires around)

D) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.

How to know which wires are for the Power On switch, Power On LED, and HDD LED?

Follow the wires into the Front Panel. Remove the Front Panel, and follow them.
(Need guidance removing the Front Panel post in a Comment )

For additional questions please post in a Comment.

I have a compaq presario v5000 and lost all sound


Compaq, actually HP, should have the drivers you need based on your exact model number. If your model is exactly a v5000, consider looking here for various drivers needed for XP and your machine

My computer want power up the green led light is on


if the green light is on then the computer is powered up, i suspect u have a defective monitor, not that uncommon, the olny way to check it is have a computer repair shop hook it up to another working system and see if the monitor turns on, if it is the monitor just replace it, monitors are very cheap right now, just bought a 19" for $89.00, mine did the same thing, green light nothing on screen.

Compaq Presario SR2150NX doesn't turn on. Front panel green light turns on but nothing else happens (no fans, no boot, no noise, nothing) Please advice


On the back of the Power Supply there should be a Green LED, When you power it on if it is flashing, this means that the Power Supply is dead and you need to replace it.

My screen stays black when you turn it on. model HSTNN-C17C which is located under the battery. Presario V5000


This isn't a desktop PC by the way. Do any of the lights come on? If not, try to run the laptop from the AC power. If the lights come on but no display, then your backlight or inverter on the LCD panel for your V5000 might be bad.

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.

Presario will not start


Hi, remove the left side of your case, turn on power and see if you can see a red or green led light on the board, if its not showing then your power supply is faulty. If the light is on then with the power off check the RAM chips are tight. if that does'nt work Then trace the cables from the front of the case, locate which is the pwr switch and unplug that, turn the poweron and then use a small screw driver and bridge the pins of the pwr switch. If this does not work you have either a dead CPU or a dead motherboard. Regards mistyman
