The issue seems to be due to defective video card on the notebook. Connect and external monitor to the PC and check if it works fine or not. You can follow the steps listed below to connect an external monitor.

1. Turn off the notebook.
2. Connect the monitor cable from the external monitor to the monitor port on the rear/side of the computer.
3. Connect the monitor to a power source and turn it on.
4. Press the Power button to turn on the computer.

At this time, please follow the instructions mentioned below for switching the display to the external monitor:

The notebook's video card supports three modes. Built-in screen only; external video only; and both on simultaneously (mirrored). If you're not seeing the image on the desired device(s), the notebook's video card is probably in another mode. Press FN + F4 to cycle through the display options: Notebook display, External monitor, both.

If you press FN + F4 once, the external monitor will display & there will be no Notebook LCD display.
If you press FN + F4 twice, the external monitor will display & there will be some shading on the Notebook LCD.
If you press FN + F4 thrice, both Notebook LCD & external monitor will display.

If the issue persists on the external monitor, then this could be due to defective video card on the notebook. However, if the display on the external monitor is fine, then the issue is with the LCD display panel of the notebook. In either cases, the notebook requires a detailed onsite diagnosis by a service technician.

If your PC is under warranty, contact HP to get available options to get the notebook repaired under warranty.

My screen goes fuzzy sometimes, and sometimes it shows double displays on one screen, it acts retarded or something. I have an hp pavilion dv2500


Could be one of four things:
  1. VGA cable from screen to the motherboard is loose or connection damaged, needs inspecting
  2. Display screen is failing, try this laptop on an external monitor, if display is ok, then at least the next problem is not the issue
  3. If the display on an external screen is just as bad, your graphics chip is going bad. On HP laptops, they use nvidia chips, which all seem to suffer due to overheating. If this is the case and you act quickly enough by stripping the laptop and cleaning out the cpu fan assembly and heatsink, you may get it working normally. If this fails to cure it, you will need to have the motherboard graphics chip "re balled"
  4. Bad graphics driver (least likely), download the latest graphics driver for this laptop

Hp dv2500 wont turn on


does the laptop plug in tightly to the power socket

if not the pavilion part to get the system power needs replacement

contact a local technician and state the power adapter plug-in on the motherboard needs replaced

these commonly go bad on pavilions

it should cost you less than 100usd to repair

or rma the laptop if you have warranty coverage left on the hp dv2500

good luck

The connecting data bus between ur laptop monitor and ur motherboard has either been at fault or else there has been some problem with the wire connection between the two......i.e it has been loosen up....

Get ur laptop checked from the hp representative and if possible get ur laptop insured under different laptop policy schemes.....

Black screen not booting


check both your power and video connections to the monitor, sounds more like a monitor power issue.
if the connections appear ok, but screen still blank, try connecting a known good working monitor from somewhere else and see if it works with your pc, if it does, your original monitor is faulty, if it doesn't, you have a pc video issue.
