Is that an original mobo from the manufacturer? if not or yes i think one of the chips might be getting burnt due to a short circuit...claim a warranty repair or replacement... it might be one of the voltage controller chips or capacitors that was burnt... might b a dust issue too

Dv4000 screen is on for a few seconds then goes black. Replaced screen balast and worked for 10 minutes, then went black again as before replacement. Should I replace the lcd screen?


No. The bulb is good. It could be the DC/DC invertor - that little curcuit board just beneath the in the LCD - or the video off the notebooks motherboard. - personal experiance points to that invertor

Boots up fine runs for awhile then shuts down for no apparant reason.


Most times if computer runs and then shuts down it is mother board over heating. It shuts down to prevent damage. Try to clean you mother board fan and also make sure no dust in the exhaust part on the bottom of the computer. You can clean it with air can for computers just make sure you hold it upright because if it is sideways or upside down it will put out freezing air and it can damage you computer. Hope this helps.

MY HP NOTEBOOK MODEL: DV9205US REBOOT FOR ONLY 5 SEC


Had the same problems with my dv9205us in Feb 2008. Called HP and gave them the model and serial #s. There is a recall on certain models due to motherboard issues. The Fed-Exed a box with a return shipping label. Had the notebook back within a week at most with no cost to me at all. Give HP a call to see if you fall under the recall.

Internet connection and taskbar


this may be down to a corrupt windows update recently installed, go to start> accesories>system tools>system restore and choose a restore date to before the freezing problem started, or before any recent updates were installed.
