Question about HP Compaq nc6120 Notebook
Posted by Anonymous on
It sounds you're facing a motherboard failure. The flashing is a code that points to a voltage problem, which in turn points to a bad power supply circuitry of the motherboard. The Maxim 1987 (or Maxim 1532 in some models) is the chip that regulates how the laptop manages the voltages, and this chip needs repairing.
This is a very common problem on the nc6000 series, and to repair your laptop you'll even need to get a new working motherboard, or repair the one you have. As it's practically impossible to find a new motherboard, it's best to opt for the repair option.
Here's a HP nc6120 laptop repair manual aka Maxim 1987 problem. The actual photos are from a Toshiba m35 repair, but the procedure is identical for the HP laptops.

This most likely ISN'T a motherboard failure. I wish I had done more research before ordering a new board.
-FIRST TEST YOUR AC ADAPTER
After you've determined the AC adapter is good then move on to the LED LIGHT CODE LIST OR A HARD RESET.

Norm.. Suffice to say these are a problem. Is it a P35 Adapter? If so look for a replacement and retry. If this does not help Check the CMOS battery voltage as crazy as it may seem but the Dell adapters are a little more complicated than a standard 2 wire output adapter. They have a 19V Feeder or main supply, The Negative or Ground as some people/techs call it as well as a 3.3V data circuit thats related to the Embedded controller chipset, BIOS and other circuits on the board. Also see if you can find a friend local with a known good working battery/adapter if you cannot afford or dont want to spend money on it. If all else fails yell back weve repaired a ton of these and they should have been included in the 5150/5160 Dell Class settlement in my opinion as they have a ton of similar components/issues..
Good Luck! Ken

Have you tried attaching an external monitor when the LCD screen is disconnected from the motherboard? this connector is located under the keyboard strip – a piece of plastic just above the keyboard.
If it works, this way, then the video cable isn’t seated properly in the connector on the back of the screen. Plugging the video cable back in should fix the problem.
I don’t know how comfortable you are with taking apart laptops but I think that this information could be useful for you.

This is taken from page 11 of the user's manual (http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c01627018/c01627018.pdf)
Blinking amber: A battery that is the only available
power source has reached a low battery level. When
the battery reaches a critical battery level, the battery
light begins blinking rapidly.
In other words, attach the charger to the laptop and let charge for at least 1 hr before trying to restart your computer.
