I am trying to recovery my old HP Compaq laptop, and this time the problem is: using HWMonitor on Windows or sensors on linux, the temperature measures are shown in the picture, but when I touch the heatsink I would say the temperature is above 100ºC!!! what do you think is the problem?...

HP Compaq NC6400 - Wrong temperature measure
Hello there
I am trying to recovery my old HP Compaq laptop, and this time the problem is: using HWMonitor on Windows or sensors on linux, the temperature measures are shown in the picture, but when I touch the heatsink I would say the temperature is above 100ºC!!! what do you think is the problem?... -
That is true, but I have not seen a speaker on your motherboard...
Also, I noticed that the 3.3V led on your motherboard diagnostics board didn't light... Maybe you should check the 3.3V line... -
Do you not have an ISA VGA adapter?Leave a comment:

Without the schematics, the things will be harder...Leave a comment:

Are you using a graphic card, right?
Are you sure this card is working OK?
The fact the processor is heating is a good thing. It means that the tension there is ok.Leave a comment:

I got it
If the coil is overheating, it means that there's an exceeded voltage across it. Do you have the schematics of this laptop on hand? You need to investigate the normal tension for this coil and why the tension is above the normal level.Leave a comment:

have you tried replacing this coil?Leave a comment:

Do the NUM LOCK and CAPS LOCK keys light up their respective LEDs?Leave a comment:

I was thinking, this notebook probably suffered a fall, could something have shorted out and damaged part of the north bridge?...Leave a comment:

Thanks for replying!
I tested the continuity of the flat cable using the multimeter on the diode scale and it is OK. One thing I noticed is that the notebook does not display video on the external monitor either, but on the other hand the keyboard responds to the num lock and caps lock commands, indicating that the system has booted...
Any ideas?...Leave a comment:

HP compaq NC6400, LA-2952P, white screen
good morning
I've had this laptop sitting at home for many years with this defect, and now I have some free time and I'd like to fix it.
9 years ago I tried to sell it to a woman, she kept it at her house for a few days and then returned it to me broken (hinge). I bought the hinge and a new flat, thinking the problem was in the flat, and it wasn't...
The screen connector part is in the photo below, I measured the voltages with a simple multimeter and the measurements were as follows:
1: 1,3V
2: 1,2V
4: 1,3V
5: 1,3V...
No activity results to display
