hp compaq nc6000 problems

[FreeEnterprise]

I filed my tip down with a dremel tool until it looked like a pin.

And I used no solder. When you touch the pin, (not at the base, up on the leg) you can see the solder soften almost instantly. That is all you need to do. Touch each pin, as you go around the chip. I did about five, then let it sit for a few seconds to cool off. Too much heat and you will have other problems...

I don't think you could even get solder down on the chip legs as they are so small... If you try to add some, you will probably end up connecting two legs together... Which would be no good, and cause weird things to happen...

Good luck.

Thanks so much for your reply. I have already done the soldering, with a 0.2mm soldering tip I bought. Luckily I think I did pretty much as you said. Not sure exactly what you mean by "not at the base, up on the leg", as the tip I had was about the same size as the tiny bead of solder on each connection.

I saw a whisp of smoke on some occasions, but even with a 10x magnification glass I bought I couldn't see enough detail to determine the solder flowed or not. I just applied about 1-sec heat each joint.

The result seemed good at first but now I am not sure. Basically I can boot consistently now, which I could not before, but I am finding it not reading the hard disk correctly. I thought the HDD must be the problem, so I tried another one from another Toshiba laptop I have and it had same problem - gets a disk read error during the BIOS HDD self test. It generally runs Windows ok, but occasionally will run very slowly, and then BSOD after the HDD thrashed away for a few minutes.

Pretty sure I need to have another crack at that chip. I know I have made some difference since before I started the computer wouldn't always respond to the power button. And even when it did, the presence of a HDD would make it hang even before the BIOS could be launched.

I have hard disc problems with my NC6000, ticking, and BSOD after an unpredictable amount of time: has anyone succeeded in installing an ide/compact flash.?

Which driver files would it be prudent to rescue from my dodgy hard disc?

I have 1.5gb ram installed, and would like to run XP in ram using a smallish flash card as a boot up rom, and using a RW cd or external USB stick to store any odd files. Is this possible?

regards Rissole

Matti you may just not have a wireless card in your laptop turn it up side down and just to the bottom left of the heat sink fan theres a little compartment open that with a screw driver. There should be a green card if it is empty you could either buy one or get a wifi card but you would need a wifi input if you were to buy a wireless card for inside the hp compaq nc6000 i would recomend one from ebay because they are very cheap i did a fast search for you and found these at the top of the list

cgi.ebay.co.uk/MINI-PCI-E-WIRELESS%2FWIFI-CARD-4-HP%2FCOMPAQ%2FDELL-&AIRPORT

So hope the Auto-IT team has helped .

Thanks,
But, it must be a wireless card in it, 'couse it works. Found the network automatically. Just I can not switch it on or off. When you switch the computer on the light is flashing.

Anyway it's a real light-minded problem just for fun... I like this machine
Thx, for the answer again

Hi,

I am intimately familiar with the classic NC6000 mobo problem, I have replaced several myself.

This is a different problem: with the AC adapter plugged in, the display becomes pixelated and garbled (after 1-2 minutes, then becomes unuseable due to the frozen display). Unplug the AC adapter and the problem goes away (immediately) and the laptop functions perfectly on battery power. Where do I begin to troubleshoot this? Is this a known problem?

Thanks.

So this happnd to me as well on my nc6000. I took the laptop apart and the ribbon cable that goes from the motherboard to the lights on the front of the laptop had come partially disconnected. I reseated the cable and it works fine now. Hope this helps you.

Hey I followed your advice. I ended up re-flowing the solder on the front and right set of legs, and the others looked in good shape. Rebuilt the laptop and it booted and has been working for a few hours.
Here is a flikr album of some shots I took with a 200x microscope with some before and afters, and the iron tip I used;

This was after reflowing with a 12W iron with a a filed down tip;



This was the tip I used;


That's a match head on the right ;-)
