Question about HP Compaq NC8430 Motherboard - 416397-001 (416397001)

1 Answer

Motherboard powerlight blinks

Water was spilled into my HP Compaq NC8430 laptop, and it went off instantly; I immediately disconnected it from any power, tried to clean up the mass on the surface, turned it upside down in order to absorb the water with a kleenex. After that, I opened it to completely dry up what was left of the water, which I did quite easily. After about 24 hrs I reassembled the laptop again, but it wouldn't boot; instead, I realized that the powerlight which is on the front of the mainboard was blinking rapidly. My visit to a local repair service brought the result, that ... as they informed me (and they told me they had made a call with the HP service hotline) ... the mainboard "is defect and to repair the damage would exceed its' value". Back home, I decided, to give it a complete disassembly to examine further where the hell a real defect might be visible. I detected nothing, but thought about looking for a new mainboard on ebay. Since then it's, well, in parts, but still complete. Today, just for a try, I connected the blank mainboard to the original power cable and to my great surprize, the "rapid blinking" of the powerlight (which was at a rate of about 4-5 times a second) has changed into a relatively slow 1 blink a second. The hp-self-service-site informed me, that the slow blinking of the powerlight on the front edge means the laptop is in standby-mode ( My question is: could it be possible that the mainboard, fo which reason so ever, is not at all defect, but "decided" to go back working again??? Thanks for your help!

SOURCE: hp pavillion laptop will not turn boot

When the users boot up their system, Windows Vista Operating System will load up every single font that they have installed in the computer. With this is make sure that they are available to the different applications, it is not certain that they all can be loaded on startup. Each additional font adds extra time to the startup. Reducing the number of fonts that load on startup to about 300 to 400 will drastically reduce the boot up time of the system.

Unable to pair samsung t729 blast with bluetooth on hp nc8430

Read the manual that came with your device. It should tell you in the manual what the default pin is. You can try 0000, or 9999, or 1111 just for the heck of's usually something like that. (not sure on the number of digits for your device, but I think it would be 4)

The keyboard and mousepad is not working

Without looking at it, I would have to say that the ribbon cable that connects the keyboard/mouse to the motherboard has been disconnected, you will need to research that. May be simple. Has there been any water spilled on it?
