HP Compaq nc6000: System looses power after 10 seconds

Sat, 04 Jun 2022 14:00:37 -0700

I've had this thing forever and out of nowhere it would turn off after turning on for 10 seconds. It was booting into windows XP perfectly fine and then the issue would return. Online is no help just saying to apply pressure on a part near the power button for the duration you want to use it, I'm looking for a long lasting solution. Others have the same issue so it seems to be a design flaw. It may help that the pcb for the power buttons is separate from the main mobo.

The power button pcb on it's own

Main mobo without the button pcb

The pcb connected

@uchetil I can solder, the thing is I'm not sure what exact chip I need to re-solder. I remember this video shows where to apply pressure when powering on. Also I remember once getting it to stay on longer than 10 seconds only turning off when I manually shut it off so I could figure out which one I held down. https://www.youtube.com/watch?v=ILLvioWt...

HP Compaq nc6000: How to enable TRIM in Windows XP?

Sat, 08 Aug 2020 03:15:31 -0700

I have an HP nc6000 that never came with a hard drive, which forced me to get creative initially until I could order the correct caddy (eBay find) and do it properly. However, an issue that I’ve always had persists even with the proper mount so there is something wrong with the drive I picked. What will happen is I’ve noticed it clicks in operation, but continues to work. I think it’s a calibration issue at this point, especially considering it came out of a T43 with bent hinges and a destroyed chassis that had CPU hardlock issues.

The issue now is you cannot find new IDE hard drives and many of the ones left are expensive, low capacity or a combination of the two. This is primarily because companies destroy them when they retire these notebooks, even though a wipe will probably be fine and the data is probably no longer relevant to their business. Because of the scarcity of good ones, I need to get creative to get around that issue as well.

One of the options I’ve looked into is doing an M.2 AHCI->IDE conversion using a 128GB SSD. It’s a bit more expensive then M.2->2.5” SATA because you need additional translation hardware (specifically the IDE->SATA bridge from IDE i915 notebooks), but it can be done. However, XP does not support TRIM as far as I know.

Is it possible to make TRIM work on WinXP? The version I have probably doesn’t matter too much, but I have Pro SP3 installed. I never installed any unofficial service packs because I don’t want to muck up compatibility and potentially make an irreversible mess without a wipe and reload. I am running No CD cracks for legally owned games to save my discs and modified files in Sims 2 Double Deluxe because of the 800x600 problem that comes up on 1024x768+ capable displays on some systems in the original SecuROM pressings that’s fixed in the Origin version. Mine was affected by that documented problem, so I had to patch multiple graphics rules files in order to fix it.

HP Compaq nc6400: Why does my laptop sometimes shut down without me doing anything?

Mon, 14 Dec 2015 10:36:28 -0700

When I am doing things on my laptop, like playing games and watching videos on Youtube, my laptop just shuts down without any notice. This only happens when I'm on battery power, and it happens at any given time, even when the battery is at full charge!

For the conditions:

Windows 7 Pro

High Performance Battery Setting

Got a new battery a few months before

Windows Aero theme for window border

Hope this here helps!

HP Compaq nc6000: no power leds, was working 1 year ago

Sat, 20 Dec 2025 04:19:41 -0700

so I don't generally use this as it's really more of a toy/ testing tool for vintage vehicle ecms and such and I quite like using it to flash gm prom units

well imagine my surprise when I pulled it out of storage and plugged it into its 100 watt replacement brick (had worked before and works on a more modern toshiba) and nothing. no lights no small clicks just completely dead. the power is making it in but maybe it's battery is just finally that dead and it needs to sit on charge for a few days

if anyone has any ideas that would be great but I will list the things I've done so far

complete disassembly to check for power making it past the ac jack
checking for bad components on the board with a multimeter after discharging the caps by holding the power button (none found)
attempted to bypass power jack at the traces leading to the converter circuit and nothing.

I do know I haven't done any damage as of yet since it's not my first time experiencing a power issue on this specific laptop and have done this before and one day it kinda just worked so idk
