You guys are very helpful, thanks

With J Lead parts the component lead is shaped like a capitol J where the bottom of the J is under the body of the component. That design was intended to save space on the circuit fab. (You can put the components closer together and increase the density of components on the board).

Most keyboards are designed such they can be repaired although I didn't look at the nc6000 carefully enough to answer that. I have repaired hundreds of keyboards in the past. Common practice is to scrap one keyboard and transfer parts (key stations) from that one board to replace individual keys on other machines. Some designes though are using capacitance for key sense and they simply have to be cleaned with alcohol to come back to life. The bad part is that you have to take the keyboard apart to do that. (Some are easier than others).

Best of luck

I am sitting where I can reach my NC6000 ( Compaq ) and it came with an Intel(R) PRO/Wireless LAN 2100 3B Mini PCI Adapter.

Now, with all due deference, the integrator I work for may have built out the field units that way but it's unlikely since they did notebook refresh annually for 1/3 of the company at a time which amounted to 3,500 notebooks a year. I don't see our integration lab opening 15 notebooks a day,,,,forever

Now you have raised my curiosity,,,,

Thanks!

Here is a close up of the problem chip. Yes, it has a gazillion posts that are the size of dust... So file down your soldering iron down to a pin point if you want to try this.


See the chip, right above the half hole ^^

That half hole is where the heatsink screws into the motherboard, which is flexed by the LCD screen opening and closing. So make sure you put some oil in the hinges and get them moving better or else it will just do the same thing again...

I would bet you could just do the pins next to the mounting chip instead of all the pins, but since it is such a pain to get in there, I just went ahead and resoldered every pin...

UPDATE... My computer quit working last week, after no problems for over 8 months and using it for hours almost every day.
I went through the regular testing making sure it wasn't my hard drive, or power related... Then stripped it all the way down to the motherboard again, and resoldered the maxim 1987 chip... for the second time this year... Still with no solder.
Put it all back together, and it has been fine since.
I also noticed that the little plastic "feet" on the bottom of the computer were missing at the back, which would make the computer run hotter than usual as it can't breath as well on my table. So I put some large stick on feet to give it more clearance around the fan and heatsink. I haven't been opening and closing my laptop as I keep it on a table now... So I think this issue is more heat related than hinge related... Or a combination of the two...

So over time you may need to do this fix again, like mine, but it really isn't that big of a deal, especially if you got the machine for "free" like I did since it didn't work!

Hi there,

I've got an HP Compaq nc6000 laptop from my sister's work. I have problem with it and I am at the dead end. Don't know what to do.



First, it checks memory for a couple of minutes. When it's finished, it
displays the following screen:

================================================== ===========

524288 Kb OK
162 - System options not set

The following configuration options were automatically updated.
Total memory installed: 524288 Kbytes
CMOS checksum invalid, default values loaded

F1 Save Changes
F2 Ignore Changes
F10 Computer Setup
================================================== ===========

If I press F1, then everything is OK. The laptop starts up as usual (Win
XP SP3). When I log in it tells me that time/date is wrong and it is 04/01/1980.


I replaced cmos battery thinking that would fix the problem but it still persist. When I have laptop plugged in power(battery is not working) and shut it down, I can start laptop without that error massage but if I shut it down and unplug power cable and then plug back in and start it I get that same error message.


Thanks in advance,

Igor

I have the same problem and I think it is cause by some kind of lost contact of some chips because sometimes it is ok but when i tried to move it. The problem persisted again.
Please help me with this problem. Surak24@gmail.com
