Internals and Construction
We mentioned that the system we originally received was essentially the base model, and since we really wanted to look at Turion X2 performance potential we had to perform some upgrades. That gave us a chance to tear open the system and see how it was put together.
One of the first major issues we have with the design becomes immediately apparent when you decide to make even the simplest upgrade. The vast majority of laptops include a small access panel on the bottom of the system that allows you to upgrade memory. Unfortunately, other than the battery latch and some ventilation, there really isn't much to see on the bottom of the laptop. If you want to add memory, you will have to pop the hood, and as with most laptops this requires removing several screws -- six to be exact. As is typical of most laptops, you will need a small Phillips head screwdriver in order to accomplish this.
With the screws on the bottom removed, you should be able to use your fingers to pry open the front of the case. We found it was easiest to start at the left front corner, and then work your way around to the front right corner. Once this is done, you can carefully lift off the front plastic panel which includes the trackpad.
This piece is connected to the rest of the system by a ribbon cable, so be careful not to lift/pull it too far until you detach the cable. If you are working on a flat surface, you don't actually need to detach the ribbon cable, which is one less step to worry about if all you're trying to do is upgrade memory or hard drive.
At this point, you can lift the keyboard up, exposing access to the memory slots. The keyboard is also attached by a ribbon cable, and if you don't need to do more than swap/add memory you should be able to do this without detaching the cable. Just be careful not to pull on the ribbon cable too much, as they can be damaged. We removed the cable and keyboard completely in order to get a good shot of the memory slots, which are covered by a thin sheet of foil/insulator. In the above picture, we have two Corsair 1GB SO-DIMMs installed. If you wanted to upgrade your hard drive, one more screw secures the drive bay, and once you remove that you can lift the drive out.
Getting down to the CPU requires a bit more work. First you have to remove the large plastic and aluminum panel. This is secured by one more screw on the bottom rear of the chassis and seven screws on the top of the panel. You also need to remove the hard drive in order to remove this panel. Once you have all the screws removed, you have to pry up the plastic sides in a manner similar to how you first open the case, and then slide the panel up and out. It takes a bit of effort, but if you find that any portions of the panel seem to be stuck check again and make sure you have removed all of the necessary screws.
With that panel out of the way, you can see the relatively large heatsink, heatpipe, and fan assembly that cools the processor, chipset, and some of the voltage regulators. There are actually only four screws holding the heatsink in place, all in the top left portion in a rectangular arrangement. The screws won't actually come all the way out as they are connected to the heatsink, so all you have to do is loosen them and then carefully lift/pry off the cooling assembly.
When you got all that done, it's pretty easy to remove the old processor and install a new processor. We did have to scrape off the old thermal pad before installing the new processor, as it had become hard and would likely have caused issues with cooling the processor. We used some inexpensive thermal paste when we installed the TL-60 (and later when switching back to the TL-50), and in subsequent testing we didn't notice any substantial difference in temperatures or stability. Once you've installed the new processor, reverse the whole process to put the system back together and you're done.
Here's a quick shot of all the pieces you will have won the system is completely disassembled. This is a picture of the bottom of all these components, since we already had various images of the tops. All told, the disassembly and upgrade process was one of the more inconvenient laptops we've dealt with, but as most people will only have to do this once or twice during their ownership of the laptop it shouldn't present too big a problem. However, given that we were testing several different configurations and had to disassemble and reassemble the system quite a few times, we grew to be none too fond of the overall design.
Besides the requirement that you take apart the front of the system just to swap memory, we encountered some problems with the wireless mini-PCI card, likely caused by our poking around inside the case. When the laptop first arrived, the wireless networking worked fine (once we got the proper drivers installed). After our first "upgrade", Windows wireless networking could no longer find our network. After a lot of trial and error, we determined that we must have bumped the card or wires in some fashion that affected the ability for the card to receive signals. We checked the connections and everything looked fine, but the WiFi networking still refused to work. We opened up the laptop again and played around with the card and the connections a bit more, turned the system back on, and the wireless network was back.
Unfortunately, it seemed every time we opened the case there was a good chance that the wireless network would fail, and eventually we reached the point where we were unable to get the wireless adapter to function anymore. Windows didn't indicate any problems other than the inability to see any networks, so most likely it was simply some point of failure in the WiFi antenna that runs throughout the chassis or on the card itself. We have used other laptops that also include bottom panel access to the mini-PCI slot, and it certainly seems that there are better locations than MSI chose, although it is also possible that we just got a flaky wireless networking card in our review unit. Our overall impression of the RALINK wireless networking card is lackluster at best, and we also discovered at one point when the card was working that the latest drivers had a severe memory leak. Thankfully, you don't have to use the RALINK networking application.

The Core 2 Duo mobile processors DO support 64 bit instructions!Core Duo does not.
randomas - Tuesday, October 17, 2006 - link
Doh! I guess I should have checked then, but all the more reason to see them both pull their weight with a real OS!Wesleyrpg - Monday, October 16, 2006 - link
hey all,im eager to see a review of the a8js, thats the laptop that i got my eye on at the moment, if asus play their cards right, the a8js could become one VERY popular laptop.
Any idea on availability though on the A8JS?

Good review, but which system was being reviewed, the Asus C2D or the MSI X2?duploxxx - Monday, October 16, 2006 - link
Nice comment, whenever it fits there results, they will publish it.. (does remember me of the time you would test 2P wood-opty in windows, but probably the result was not as expected of your sponsor). Also the memory issues do question your results......the core2duo is for sure the better performing one. Few months ago the X2 versus coreduo was a tight battle, but we all saw the core2duo outperforming the coreduo with glance, so the same thing happens with turion. Intel made his design for laptop and changed it up to desktop and server, AMD did it the other way around.... so for a 3year old design I think it was rather good against all those updating Mobile en core technologies from Intel.
Now from an other perspective. Most of the laptops are supplied with Intel internal graphics. How Will this perform against the ATi Graphics? that would be an interesting review.......

ATI Xpress 1100 is about twice as fast as GMA950, plus it has full DX9 support (though not SM3.0). Problem is, it's pathetically slow still. I mean, what can you want that the Xpress 1100 can provide but the GMA950 can't? 20 FPS at minimum quality in HL2? If you want 3D performance, I'd say the 7700 in the A8JS is a good starting point. X1400 and GeForce 7400 are both substantially faster than Xpress 1100, buth still pretty sluggish for actual 3D work. X1400 is still okay for video playback and older games (as is 7400), but you can get 7600/7700 for about the same cost I think.JarredWalton - Monday, October 16, 2006 - link
MSI today, ASUS later this week. It's probably already clear which one we preferred, but there's more to say about the ASUS and putting out a 14000 word article seemed like overload.piesquared - Monday, October 16, 2006 - link
Yes, i know, and sorry for the sarcastic question. I guess i'm just wondering why so much content on the Asus solution, when as you say there will be a seperate review later this week. My overall picture of that article was that AMD's solution was a steaming pile of mess not really suitable for anyone. At least that's the impression i(and probably most visitors that read or will read it, so i guess it was successful that way) got, regardless of any conlusion throwing it a bone here and there. What i can't understand is why MSI would even offer up such an abomination for review!! ;)BTW, i did think it was a very good article, aside from the above mentioned slant that seem to ooze from it..

It's basically a case of getting an okay system, but we would say there are better options out there. If the MSI is cheaper, faster, has more battery life, or some other benefit than other competing laptops, great. It's basically at best equal to other ultraportable options.The ASUS W5F with Core Duo is about as fast (with "slower" integrated graphics, though it doesn't matter much), but it costs more, so there you could say the S271 is "better". Unfortunately, there aren't many faster Turion X2 notebooks around, other than the MSI MS-171772 mentioned in the conclusion.
If all you're after is ultraportables, the MS-1058/S271 is about all I see for Turion X2. It does tend to be about $100-$200 cheaper than any Core 2 equipped ultraportables, or about the same cost as Core Duo equipped ultraportables. In that market, it has a place. I'm not a huge fan of ultraportables, but some people are. I'd personally rather carry an extra 2 pounds and get a 14" (or larger) display.

you rip apart a closed system not designed to be opened up by the consumer, fiddle around inside, then complain when things don't work? even the complaints on memeory compatability seem lame.
