I will post various technical specs that are not specified in Acer's specifications first:
Battery: Internal, same battery as in Acer Aspire M3 ultrabook, model AP12A3i (31CP7/67/90) 11.1V 4850mA, 54Wh
Hard disk drive (HDD): Western Digital Scorpio Blue, 2.5" SATA, WDC WD5000LPVT-22G33T0, 7mm height, not 9.5mm -replacement SSD must be 7mm height!!!

Backlit keyboard can be enabled/disabled via Fn+F9 key.
Processor Tj. Max is 105 C.
The 20GB SSD has a 4GB hibernation partition (which will have to be changed if RAM is upgraded) and a 14.64 GB partition used for caching via installed ExpressCache software from Diskeeper. There is a 16GB hidden recovery partition on 500 GB HDD from which DVD recovery media and drivers DVD can be created via Acer eRecovery Management.
Acer's free 'Theft Shield' solution seems to only provide an audible alarm if laptop is carried away more than a few feet from a connected Wi-Fi hotspot -I am assuming it used WiFi signal strength as a trigger, and if it detects a noticeable change (caused from movement), it sounds an audible alarm from the system speakers.
In order to use the hardware-based Intel Anti-Theft (AT) feature, activation codes may be purchased separately (~$25 1yr, ~$40 3yr). The item descriptions/part numbers for US market are:
BXIATSC1YRENG Intel Anti-Theft Service Activation Code Card 1YR English Retail
BXIATSC3YRENG Intel Anti-Theft Service Activation Code Card 3YR English Retail
In addition, Acer included a URL link on the Windows 7 Start Menu for a trial of McAfee branded Intel AT service, which I just enrolled in. The way it works is that the downloadable software client that gets installed upon activation via your web browser synchronizes with the server to check for the existence of a lock activated via web browser or (good luck with this one!) phone support. After a few painful phone conversations with phone representatives -first at McAfee support, then at Intel Anti-Theft support, one stated that the activation period for the service was for the duration of ownership of the product. I still doubt that, given that the terms & conditions I revisited when I signed up mention that if no term is given it would be for 1 year, so I am assuming that is how long it will really last, but we'll see.
Anyway, so if the anti-theft software syncs with the server and finds an existing lock in place, it immediately powers off the computer and sets the lock flag. When powering up the computer again, you are greeted with a screen that it is locked. The web interface permits you to customize with a short message with (presumably) contact information to return the laptop to you, but you could put any text in that field. In addition, via the web interface, you can set a pre-defined lock time choosing from disabled or 3-30 days in 1 day increments -so if the PC does not sync with the servers via an internet connection for that amount of time, it will lock itself the same way as explained before. By default, the pre-defined lock time is 21 days.

Now for the actual review -I purchased this because I needed/wanted a portable NVIDIA Kepler based workstation for developing CUDA code. Currently (as of 07/12/2012), NVIDIA has a Verde 304.79 driver that supports CUDA 5 Preview -there will eventually be a non-beta driver, but in the meantime this driver works for my purposes. Access to the DDR3 memory slot requires removing all the back screws and using a platic pry tool in order to open up the top case, in addition to removing at least 3 Zero-Insertion Force (ZIF) connectors for keyboard, keyboard backlight (KB) and touchpad (TP), which are all in the bottom part of the case, so pry and lift from the LCD side. Be very careful, as it is VERY easy to break these type of ZIF locking connectors. Disconnect the battery cable also, just to be on the safe side. Replacing the HDD with SSD is possible, but also requires taking the daughterboard (DB) that contains the SD slot/headphone/mic port out -held by two small screws, as one HDD screw is underneath it.
Replacing the ODD is easy, just one screw holds it in. However, I suggest being VERY careful while removing/replacing the ODD, the standoff holding the drive became loose on the laptop I purchased from the previous retailer -it is held down poorly to a thin piece of metal attached to the bottom of the palmrest, boo Acer! I successfully used super-glue to re-attach it, but it is not an easy task, it took a few tries. If you are replacing the drive with another one, check the thickness -if it is just a little bit more thick, remove the top cover entirely, put the drive in place with the screw bracket over the standoff, and screw everything back together. That way the standoff does not have force applied to its side, and is MUCH less prone to breaking off. In fact, I'd say loosed all the other bottom screws before attempting to take the ODD out in the first place. It's a tight fit... that's what she said! ;) For that matter all the clearances/lengths of FFCs/ZIF sockets are very close and not much give is left, it is good to keep in mind if you decide to open up the system for upgrades/repasting or some other reason.
I figured this hardware review would help any tech-inclined people that want to try to Hackintosh this or use Ubuntu/some flavor of Linux.
Unlike the previous TimelineX generation that throttled the CPU to avoid overheating, the M5-481TG seems to throttle/downclock the GPU to 270 MHz. This proved acceptable in my initial testing with Heroes of Might and Magic VI and Metro 2033, as gameplay was decently responsive, even at the highest settings. (Caveat, New Game/Load/Quit screen of Metro 2033 had black bands when using DirectX 11, changing to DirectX 10 fixed this -probably a driver issue). In my opinion throttling and not the greatest ever panel are the true downfalls of this laptop, and account for my 1 star deduction. Other than that, I think this one is a keeper for a while!
Not-so-technical review -The touchpad can be very fluid, especially with a lighter touch. I'm still getting used to physical buttons being part of the touchpad, so I cannot comment much. There does not seem to be any flex on the keyboard -it is screwed into the palmrest/top cover from the inside with plenty of small screws. There is, however, some slight flex along the top part of the palmrest, but nothing that creaks/cracks. Viewing angles for the LCD screen could be better, but for a laptop that's about 1/3 of the price of a MacBook Pro model with Kepler graphics there had to be some compromise.
The SSD hard drive caching the HDD is nice if you're not used to SSD speeds -I am, and it feels slow. ;) I mistakenly ordered a regular form factor (9.5mm height) SSD to use, only to realize that the HDD is a low-profile 7mm height. I was able to return it and purchase SAMSUNG 830 Series 2.5-Inch 256GB SATA III MLC Internal Solid State Drive (SSD) MZ-7PC256B/WW, given it is a 7mm height, and will fit. I have used Crucial M4s and Plextor M3s, but this Samsung sounds quite promising, and faster write speeds compared to the others, so it's a worthwhile upgrade.

I like Acer as they usually make very solid products for the price and have much better support that Lenovo... But sadly there is just something very wrong with the 14 inch M5-481TG-6814 model.While the notebook is still good value for the money, playing some of the more recent games at higher settings will utterly destroy it AND there seems to be no sort of built in overheat protection. Planetside 2 and The Secret World, while not too graphically intensive will bring this ultrabook to it's knees.
Using it as an actual laptop (the way it's meant to be used) results in damaging the system, however these problems go away with a very cheap add on. This is one of the few notebooks where I absolutely MUST suggest that you also get a decent laptop cooler.
The Good:
About 6-7 hours playtime when doing anything but gaming.
USB 3.0.
Third gen Intel CPU + GPU.
HDMI.
SSD for (almost) INSTANT on!
Full sized back-lit keyboard!
14", lightweight form factor.
Great price if purchased elsewhere (I got mine slightly cheaper and with a $100 gift card).
Good sound for such a small notebook.
RAM can be expended to 10GB (with an extra 8GB stick).
Fairly powerful Nvidia GPU.
The Bad:
Only ONE slot for a RAM upgrade (the other 2GB is built in).
Comes with a lot of pre-installed useless software (bloatware).
The 20GB of SSD is NOT accessible. Yeah, that's right. No idea behind the reasoning on this one.
It gets hot REAL fast if you start gaming. To the point of actually burning your lap. This is the hottest notebook I have ever owned, and I had plenty.
Flaky wireless. Lots of dropped packets. Fixed easily and cheaply by buying another adapter.
Replacing the HDD, WiFi card, or even RAM requires unscrewing over a dozen screws (around 14 to 16 actually).
Screen resolution is limited to 1366 x 768. This is a WASTE of the powerful Nvidia GPU in this unit (which is good at overclocking, but should not be because of the intense heat the laptop already experiences).
While playing graphically intensive games, this laptop's tiny three cell battery becomes nearly useless. You will get a few hours (at most) of gaming done unless the system is plugged in.
The Ugly:
My first M5-481TG-6814 worked great during my initial Planetside 2 playsession. After about three hours of gaming, it got so hot that it shut down. Turning it back on failed. It just died. Since it was still during my first week of purchase, I contacted the Egg and had them replace it.
This time I bought a single fan, low profile cooling pad to keep it on. My second M5-481TG-6814 still got a bit hot and eventually the screen started to artifact while gaming (at least it didn't shut down by itself). Restarting would fix it for a while, only to have the problems reappear in a few more minutes of gaming.
The third (and I hope final 6814) is sitting on a dual fan cooling pad, which rises quite a bit higher and keeps it relatively cool. No issues so far (for a few weeks now actually), but the trade off is that this ultrabook is now not nearly as mobile as it was designed to be.
Conclusion:
If you are in the market for a laptop that you can use just for browsing the web, watching movies, and word processing do yourself a favor and get something (much) cheaper.
If you are in the market for a gaming ultrabook, the Acer TimelineU M5-481TG-6814 is a good purchase for the price, just do yourself a favor and buy a nice cooling pad...Or you could get a much nicer desktop at a fraction of the cost, since with a giant pad this thing becomes a monster (defeating the ultrabook purpose).
If they just solved the heat issue (by adding more/better fans and better heatsink), this would easily be the best ultrabook for the money.
UPDATE --I ended up returning this ultrabook because the massive cooler prevented it from really being mobile. For $120 more, I got a much better (and cooler) machine. It also came with a GT 640M LE, and I managed to overclock it to 850MHZ (with a simple bios flash), allowing me to play all the games I wanted at maximum settings.

Honest reviews on Acer TimelineU M5-481TG-6814 14-Inch Ultrabook (Gun Metal Gray)
I'm not too ashamed to admit that I mostly chose this laptop for it's low price and ability to play Guild Wars 2. The laptop boosts very fast and plays GW2 on medium setting very smooth and nicely. I tried it on the highest setting as well, although the graphics was great, the game play slowed down a lot. The LED lit keyboard makes it great for working in the dark. However, there are a couple of things that really bugs me about this laptop.1. Connection to Wifi. Compared to the three other laptops in my house (Toshiba, Dell, and ASUS), this computer has issues getting enough wifi signal. I have to sit very close to the router for the wifi bar go to fill up. If I'm downstairs, it's connection will be very weak and sometimes with no signal.
2. Overheating. The fan is located on the top right side of the laptop. It overheats to a point where it burns my skin. I use a cooling pad with it to reduce the overheating, but that greatly reduces the laptop's portability.
3. Only two USB connections and they are both in the back. This is not very convenient at all! My boyfriend got me a USB hub to go with it...but it's such a pain in the butt =(
However, overall, this is a great product! The smooth surface makes it great for laptop decals! :D
Find helpful customer reviews and review ratings for Acer TimelineU M5-481TG-6814 14-Inch Ultrabook (Gun Metal Gray)
Pros: The best thing about this ultratop (half ultrabook, half laptop) is the large amount of features wrapped around a sexy aluminum shell.-CPU-
The 3rd generation Core i5 allows for great battery life but overclocks itself to gain horsepower when you need it.
-GPU-
The main deciding factor in me buying this laptop is the Nvidia 640m 1gb video card. It's a powerhouse that can handle almost anything you throw at it. I've tried out crysis on High, Max Payne 3 on high, home front on medium, portal 2 on high all with no struggle at all. This laptop comes with nvidia optimus so it only uses the nvidia card when you need the processing power. The other 95% of the time it uses the on board Intel 4000 graphics card as an energy saving measure.
-Size & Shape-
This laptop is very small under an inch but very dense. It's technically a ultra book but with a DVD drive. The aluminum skin allows the computer to stay clean.
Cons: The upgrade capability is nonexistent, there are no user replaceable parts on this laptop including the battery which i confirmed with Acer. The non removable battery is an non-issue because it is a lithium polymer battery with a lifespan of ~ 4 years.
I upgraded the ram to the 6gb limit and it required me to remove ~12 screws on the bottom and hold the keyboard panel up while i swapped out the ram stick since there are ribbons connecting the mouse pad and keyboard holding both halves together. It has 2 GB stick that is integrated on the motherboard but it has a single ram slot which can be upgraded.
The reason why I wanted to upgrade the ram is when the computer is using the Intel integrated video card it takes ram away from your computer giving a high idle ram usage ~ 75%, which makes things somewhat slow for multitasking. This is a non-issue during gaming because when using the nvidia dedicated card it has its own ram and frees up the ram used by the Intel card.
Other Thoughts: --Pros Continued--
-Sound-
The sound is amazing using the Dolby home theater sound system. It generates very loud and rich noise that will fill a good sized room.
-Keyboard-
I like the island keyboard, it makes typing a enjoyable experience. The back-lit feature is very nice and adds to the luxuriousness.
-Ports-
I only has 2 USB 3.0 which is alright considering its part ultra book, but also has a HDMI and Ethernet port. I use the HDMI port to connect to my 39" television as a monitor which gets around the whole low resolution laptop screen that most people are complaining about. The screen can only display 1366x768 but can output higher though HDMI.
-Hard Disk-
Nothing too special about the normal disk drive but the 20gb SSD is mostly hype. It only used during the boot up, hibernation and standby processes and does nothing during actual computer use.
Overall I love my new Acer and have no regrets!
