    NC6000 abruptly turning off, Or orange light

    I have read all your posts and my son has a NC6000 and his started doing this as well. I am an electronics tech so this stumped me thats how I stumbled across this posting. I tried everything suggested and nothing would completely resolve it this issue would return. SO here is what I did to fix this issue.
    Dis-assemble your NC6000 remove the fan and the gold pad the fan sits on on the motherboard is dirty along with the connection side that the fan sits on the motherboard. Take a #2 pencil and use the eraser and clean both of these. If you so desire remove the power board and clean all these as well. Re-assemble and tighten screws accordingly. You will no longer experience this issue. If you do follow the steps all over and clean a little better. The issues resides with the continuity between the fan and the board the circuit is being broken and thats why this issue is there.
    Once you accomplish this you will actually see an improvment in the overall funcionality of the unit. I have bumped it around shook it and it still powers on every single time and will run until I turn it off.

    Power up problem with hp compaq nc6000

    Using an old nc6000 for writing. Would not charge the battery. Looked at all the expensive solutions then tried most obvious one - the power cable being worn out. Replaced it at a cost of under $10. Problem solved. No motherboard replacement, no battery replacement. Things are working just fine.

    All you have to do is remove the keyboard, battery, disconnect AC, remove the red/black lead from the Mobo (next to the RAM). You'll see it when you lift up the keyboard. Wait a few minutes (I waited ~15 minutes). Plug in AC boot up. It'll start with memory count up then give you the choice to go to F10. Go in re-set the passwords, save BIOS. You are good to go put it all back together - the cmos password is gone -that should do it nothing else is needed...

    That could very well be the bad button board I talked about above. No lights was very common for me with that problem.

    Any Ideas?

    As I state above I have 18 of these laptops. One has me stumped. Got it running again, but it runs slooowww. I reformatted the drive, changed memory, changed the hard-drive, swapped the screen, swapped the button board and nothing, It works it boots but is slow on screen refreshes and launching programs. It also has a strange rolling flicker on the screen before the desktop appears. I am thinking it might be the video chip or the main processor, but really I have no idea. I ran a speed test and it performed similar to my others. Any thoughts before I change out the mother board?

    Comments on nc6000

    I have maybe 18 of these laptops. I have repaired them various times. Replacing keyboards, memory, hard-drives etc. I have not as yet re-flowed any Max chips. I started the process of repairing 8 of my laptops that would not boot and discovered some interesting things. Half of these were not working because the button board was bad! Two just needed the memory reseated, and only two of the eight that would not boot remained with what appears to be the Max chip problem. They will boot when I put pressure above the chip at the fan connection point. I plan on re-flowing these laptops this week. What I observe as the problem is as noted by others there is flexing of the circuit board from the screen hinge. I propose and plan to remove the fan screw at the Max chip location, also cut off the screwing post below and also cut off the connection fin on the fan so there is no contact of the board to the case at this point. Then I will use double back foam tape on the bottom of fan to secure it at the radiator point. Let my know what you think.

    Hi,
    I also have a nc6000. I managed disassemble it and with the help of my brother who happens to be an Electronic Technician, we managed to locate the Fuse: L1013 & Capcitor C206.
    He verified that the fuse was ok but when he checked the capacitor, it wouldn't give the value.
    Now my question is, what is its value? or rather how did you know that the one you replaced it with was the right one?

    So anyone using the suggestions here I stripped down my nc6000 (which wouldnt boot up unless I applied pressure to f12 area), filed down my soldering iron to a fine tip and just briefly touched it to each of the connectors on the maxim chip. Reassembled it and Voila! typing this on it now. Don't have much soldering experience and did a fine job, thanks guys!

    Is your nc6000 not booting up? the fan kicks on and the orange lighting bolt lights up and then it turns off?

    see previous page for the fix, as your Maxim 1987 chip has overheated/flexed and caused it to not be connected to the motherboard. Pressure on the silver part of the keyboard by the right hinge may let it start for a while but to "fix" it you need to fix your motherboard.

    see the chrome plate that covers the main chip. The maxim 1987 chip is right between that and the mounting screw plate where the heat sink attaches.

    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...
    Also... See the little brown capacitor? on the left of the maxim chip? Notice the bottom of that looks strange. It isn't connected well, the tech pointed that out, and fixed it as well.

    So it could be both of these are suspect... It should look like the ones above, solid silver, the black hole is where it wasn't connected well to the board...

    Anyway, I wouldn't solder it yourself as that has turned out to be a temporary fix, I would take it in to have a professional with a heat bed fix it... Especially since it should be low cost, for what should be a long term fix.

    Pressure on the fan assembly would cause it to boot up ok, for a few minutes then it would lock up.

    So, I stripped the computer all the way down (the Maxim 1987 chip is UNDERNEATH the motherboard, in the corner where the heatsink screws to the board.

    Also, my hinge on that side was really tight... So I used some tri-flow on it and moved it around for a while (did both hinges at the same time) they are still stiff, but better than they were.

    Finally I found the chip, (my youngest daughter helped me find it.) I then got my trusty soldering iron... Tip was WAY too big... Borrowed a friends... His was too big too...

    Went to the garage for my "old" iron. It had a smaller tip, and was adjustable down to 15 watts. (better for board repair, less heat is good). I then filed down the tip with my dremel tool until it was very sharp. Then touched each prong with the iron, (you can see the solder move almost instantly when you touch it) Make sure you let it cool between as you don't want to fry the chip. I also took off the metal bracket around the main chip as it was so close to the Maxim 1987 chip that my iron couldn't get in there without removing that...

    Before I started I looked and looked, and couldn't see any not connected... But, figured since I was in there might as well try it... Laptop was dead anyway...

    After soldering I put it all back together. (tip, the little ribbon holders are easy to remove with a small flathead on each side, the clip stays on the thin cable just pulls out when the brackets move up about 1/16th...)

    After it was all together, I fired it up, and it worked perfect. I have started and restarted about 20 times, since yesterday when I did it. It seems to be working fine!

    Thanks for the tips guys. I took a picture of the chip on the board if anyone wants to see it. (its at home, but I can upload later if anyones interested)...

    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!

    Update time again... So, after my last "attempt" to fix mine, I replaced the computer, and now my oldest computer wasn't powerful enough to play the latest "horse" game my kids want to play...

    So, it was time to look at my NC6000 gathering dust in my workshop. I took it apart again, and took out the motherboard. And since I knew that the maxim 1987 chip was the issue, I took it to a local computer repair shop and asked them how much to resolder that chip. (as they have the tools to do it right).

    $25. later I was out the door with all the chips on that edge of the board resoldered professionally.

    I put it all back together and it works great.

    This is my new recommendation. Instead of fixing it yourself, go ahead and remove the motherboard and take it in to a professional for the fix. They should give you a really low price as it literally took the guy 8 minutes to resolder it...

    It is working great now, and I will update you guys if I have any more problems. My hinges now move freely and now that I put those felt feet on the bottom, it doesn't seem to be as hot as it used to get. I also removed the little panel next to the heat sink to allow even more heat to escape. (heat is bad for electronics).

    Good luck!

    Another nc6000 with the maxim 1987 fix

    Hi guys. First, thank you all for the great thread. No doubt it has helped many people. Here's my case.

    A customer brought one of those HPs to my store for service, complaining that it doesn't power up. After reading through this thread I advised her to try pressing the top right corner in order to "assist" in the power up process and it was a solution at that moment. A month later, though, she came again and the notebook seemed totally dead this time. For a few hours of playing with it, it only turned on twice and didn't last long. Then I decided to go for the better fix and took it apart. I found that Maxim 1987 chip and gave the whole motherboard to a professional solderer to take care of it. I couldn't be bothered to find such a small tip and a steady hand

    Anyway, more than an hour of testing so far, after I've reassembled it, the problem seems to be gone forever (I hope). It powers up without any effort and never hangs up while working.
    The professional solderer said that she looked at the chip under a microscope and she didn't notice any bad connections or broken legs, but resoldered all of them eventually. She was even kind enough to look around the chip and did some resoldering on resistors and capacitors that are placed there, as well as the whole power connector.

    My final advice to everyone with the same problem is not to try any temporary solutions like pressing and tightening. They seem to only worsen the situation after some time. Just go ahead and fix the Maxim 1987 chip, as it is the only thing that creates trouble.

    Thank you once again for the great tips!

    No video after screw trick.

    I also had the pwr up - no boot issue. I followed the fan screws instructions and it worked for approx. 1 - 2 hours, then the screen went blank. (no video) Anyone else had this and is there a solution?

    Re: Boots up ok - no video.

    Thanks in advance.

This would ensure that you will not overtighten, enhance better contact and the Aluminium foil serve as a additional padded conductor. Hav Fun!!
