Try pushing on the upper right corner of your laptop, above the home key, does it start up again?
If so its the maxim chip

if not take one so dimm out and dissable wireless.
Could also be your battery not charging because a battery or power cord malfunction.

It would seem that your BIOS has become corrupted somehow. First try entering your BIOS setup. I believe for HP computers when you press power tap the F10 key until it opens. There you can try to reset them in some fashion and save. Try rebooting. If that fails then remove the battery and repeatedly press the power button for about 10 seconds.. (make sure it is also unplugged, this is to discharge the power from the system) then replace the battery and try booting again. Otherwise it would seem that you might have tried to load the wrong BIOS into your laptop. Check with HP then if you are still covered or not. :/

My HP Compaq nc8000 will not start up correctly. When i hit the power button, only one green LED comes for a few seconds, then a yellow LED (which is the charge light) it sounds like the laptop is powering...


Check it is powering laptop,if not the jack has bad connection and not connecting to mainboard constantly,
Dobt thats what is happening in your case but need to rule it out for next step.
Remove the battery then try ac adaptor on its own.
Next try removing ram,insert one stick only,next sub it with other stick only,if still no good remove hard drive,you are attempting to get bios start screen to show up,if still no good you may be looking at mainboard power regulator ic fails,which are a real problem on some compaq models this also damages other components on the mainboard(google search will reveal what im on about)
Dont remember offhand but if its the type that has common mainboard fail its not worth repairing as the new boards always fail eventually due to same problem.
There are also light error codes in the back of the manual and available online to diagnose this by the type of lights showing up.

I have a toshiba satellite laptop the screen is black


Shutting the computer down could be done by holding the Power Switch down for 10 seconds, rather than unplug/no battery "solution". A blank screen is more often than not caused by the failure of the screen's backlight. Plugging an external monitor in the ext monitor port would verify the computer still works, and I am sure it does.

Blank screen. Remains blank


Power down, remove the battery, remove the power plug. Hold down the power button for at least 30 seconds. Remove and reinstall the memory module(s). Re install the power plug and try to power back up and see if it works. If it does, reinstall the battery ad you're done. If not, get back to me for some more ideas and further diagnosis.
Thanks and have a good day!

Hp ze2000 shuts down


Without more information I cannot be sure, but I would say that it could possibly be set to use an external monitor. There is a FN key command to switch between your LCD Screen and an external screen. Try that. If you have an external monitor that you can plug into the VGA connection, that should tell you for sure. Good luck.

My nc8000 shuts down after few seconds and starts after power plugged in or battery inserted


Hi Turecki, It's a moderately easy fix for this common issue with HP/Compaq Laptops. Simply go to ebay, purchase an "inverter" board built for a NC8000 laptop can range from $10-$50 just purchase one with a minimum 6 month warranty. Its about a 0.5 inch by 15 inches. Unscrew all of the tiny phillips screws located and hidden behind black rubber covers on the LCD screen. Pop off the plastic LCD cover and replace the inverter board located at the bottom of the LCD (plug & play). Put it all back together and voila...problem fixed.

Have fun and practice some repair skills.
