HP 2133 Mini-Note Dissection
I felt a little daring tonight so I took apart most of the Mini-Note and took some pics along the way. Enjoy:
Mini-Note with the keyboard off
Keyboard and top shell off
CPU and North Bridge Heatsink
South Bridge
North Bridge
Empty!
Underside of motherboard
PCI Express Chipset I think
Backside of wireless card
Frontside of wireless card
And finally the money shot:

Do you think it’d be feasible to replace the fan with a slightly larger and slower one? I have the same MiniNote as you, the 1.6 GHz one, and the fan is constantly on.

I hope you were able to put it back together.

lol, yeah it’s back in one piece…it took a few tries though

Curious, how did you get the top shell off?
I was tinkering with mine earlier after seeing this, I removed the only two screws that I could see holding it after removing the keyboard. I dared not go any farther after that, it didn’t seem to want to cooperate.

You need to pull the rubber feet off and get the four screws there. Be careful because they’re actually attached by thin rubber piece to the inside of the case.
Also the front right screw (the one on the express slot side) is a pretty tricky to get back in, lol. I’m not sure if it needs to be removed to open the top though, so try it w/o taking that one out.
Once you get the screws up, open the top back up and grab on of the corners by the screen and work your way around.

Thanks for the nearly instant reply Josh!

So before I get too brave and do take mine apart, I’ll tell you what I was thinking the other day.
I’ve got some Antec Formula5 thermal paste. Using it in systems where I’d previously used the paste that came with the processor resulted in a nice drop in CPU temp.
I was wondering if it might not be benificial for the Mini-note as well?
Did you use a similar paste when you reassembled yours? If so do you have any impressions?
I’ve made sure and had mine warmed up and recorded CPU temps to compile a program. Planned to recompile the same one with the new thermal paste and see if there was any difference.
I’ve got all the screws out, just not brave enough to crack the top shell off of there yet.

@sparky
Hehe, just caught me at the right time
I really wanted to try some new thermal paste as well, but didn’t have any. I just carefully scraped it back in a pile on the heatsink with the flathead screw driver on my pocket knife :/
It probably wouldn’t hurt to try it out. I’d do it if I had some… I would love to see the results either way.
Just out of curiosity, what temps are you getting right now? SpeedFan is reporting around 55c for me.
@mikael jannson
It seems like a pretty tight fit… I don’t know if you could get anything bigger in there.

@Josh
It ranges depending on what’s going on.
I’ve seen it idle as low as 47 (unusual) normally around 56C or so. Running Ubuntu and Enlightenment - e17 window manager.
When I compiled the program it ran up to 72C.
Using the Antec paste dropped the temp of the computer I’m using right now from idling in the lower 40sC to idling in the upper 20s C. 33C right now as I’m using it. I figured it couldn’t hurt, that is, if I can successfully disassemble and reassemble my Mini-note!

They put waaaayyy too much thermal paste on the CPU. There should only be a very thin layer of paste on there. That is a ridiculous amount of paste on there, that would actually hinder cooling.
Thermal paste is designed to fill in the tiny microscopic indentations on the surface of the CPU die and heatsink that causes air pockets between the heatsink and CPU die, so only a tiny tiny amount is needed, it’s not supposed to be slathered on there like that. Too much and the heatsink and die won’t make proper contact and it will run hotter than it should.

Ok, so I got brave this AM, thanks for the pointers Josh.
I dissasembled far enough to remove the heat sink/fan unit and clean up the CPU and north bridge with some rubbing alcohol after carefully removing the paste.
I put a THIN coat of the new paste on and rebooted. Previously after boot the computer was at 59C and cooled off a bit at idle. This time it booted up at 40C and is climbing to 44C at idle. Wow!
Looks like it’s up to 66C while compiling the same program. 6C cooler than previously.
I’ll report back what it’s like under normal usage but seems encouraging.

Well, now that I’ve run it a few hours and compiled the program again, I’m not seeing any gain from the new thermal paste.
It’s running the same as stock. So I’d say it’s not worth the effort.

Hi all,
I need a BIG help!!!!
I have just received my HP 2133.
Unfortunately the LCD was damaged. I´m in Brazil now and can´t get help at HP support.
Where can i buy a new LCD??

How hard do you think it will be to replace the wireless card with a 802.11n version? Any recommendations?
May 30th, 2008 at 5:56 pm
Thank you for the dissection!
I was looking at the site to download the drivers from VIA (http://linux.via.com.tw/support/downloadFiles.action), and I wasn’t sure what driver packages I needed to download, since they were listed by chip numbers.
Suse’s built-in ‘Hardware Info’ screen didn’t help. I ended up googling for “hp 2133 south bridge” and found this page, and I could clearly read the North/South bridge chip numbers CN896 and VT8237S. Now I have downloaded the correct open source drivers from VIA for the graphics and IDE devices, and will try to build .deb’s from them.

Does anybody know if the C7-M can be upgraded to the new 64 bit L2100 CPU? Where would I buy the new CPU?
May 31st, 2008 at 3:00 pm
Technically the Nano and C7-M are interchangeable, but you need special equipment to get the CPU off the board. VIA uses Ball Grid Array soldering which needs special equipment to do:

to make the 2133 30c or more cooler
simply remove the inside grill on the side with a screwdriver.
airflow increases by 60-70%
my temps went down to 35c-40c
July 3rd, 2008 at 8:19 am
Hi…the ven grid can be removed from outside without open de mini note? please help…
this is a wondwrfull machin under xp, the only issue is the heat and the fan working all the time.
Sorry for my bad english.

This site is probably to far above me but maybe someone can tell me. My music (i tunes as well as my own recorded music) is skipping on my 2133. They did not on my Pavilion. Why is this? Is there any way of fixing it? Thanks for any info.
