ASUS U41JF: Granting Arrandale a Stay of Execution

We’ve given ASUS’ U-series of laptops/notebooks plenty of praise since we first looked at the UL80VT back in late 2009. As one of the forerunners for switchable graphics, and sporting a large 8-cell battery that managed to last over 14 hours in ideal circumstances (or “only” about 10 hours for moderate Internet use), it had plenty of good ideas. When NVIDIA launched their Optimus Technology a few months later, seeing ASUS as the first major OEM to support the feature was hardly a surprise.

Time passes quickly in the computer world, and devices that were once cutting edge start to look dated and slow. Overclocked CULV processors and G 210M/310M graphics were fine in 2009, less so in 2010. These days you can’t swing a power brick without hitting an Optimus enabled laptop, and while we liked a lot of the updates to the core platform in ASUS’ U30JC, we had two chief complaints: the LCD and the GPU.

Roughly 18 months after the first “modern” U-series laptop, ASUS is finally addressing at least one of our complaints. We’ve seen faster GPUs with Optimus in their N-series laptops (i.e. the N61JV, N82JV, and N53JF), but those all cut the battery to a mere 48Wh capacity instead of the 84Wh we’ve come to know and love. Now we finally get two new parts, the U41JF and U31JG, where we get a midrange GPU with a large battery, with a reasonable price as a bonus.

Ah, but there’s always a catch, and in this case the catch is Arrandale. Sandy Bridge launched in January, was delayed in February thanks to the Cougar Point chipset bug, but is now rolling out to the four corners of the world; however, the new U-series laptops are still using the older Arrandale dual-core processors. How much of a difference will that make in performance? Can overclocking, battery capacity, and other features improve the situation? Here’s how the U41JF we received for review specs out.

We’ve seen nearly every item on this list at some point, and all of the major features are present and accounted for. Let’s focus on the areas where the U41JF isn’t just another run-of-the-mill laptop. The HDD, DVDR, audio, and networking are all common items. As far as missing features, there are no USB 3.0 ports, no eSATA, no FireWire, and no ExpressCard. I’ll be honest: out of all those, I only sort of miss eSATA and USB 3.0; I’ve never used 1394 or EC on a modern PC, though if you need any of these ports you’ll have to look elsewhere. Let’s move on to the extras.

Starting with the CPU, while ASUS lists support for the i5-460M and i3-370M/380M, our test sample came with the i3-380M. Clocked at the same 2.53GHz base as the i5-460M, it lacks support for Turbo Boost. ASUS compensates for this by providing a 15% overclock (153MHz bus vs. 133MHz standard) when you enable their “Power4Gear High Performance” power profile. On the flipside, ASUS’ Super Hybrid Engine (SHE) also limits the bus speed to 100MHz when you choose the “Power4Gear Battery Saving” power profile, along with the locking the CPU multiplier at 7X to 9X. If you prefer to run at stock, you can disable SHE (along with the over/underclocking) in the BIOS. Speaking of the BIOS, ASUS also supports UEFI mode in the BIOS if you wish to enable it; we didn’t test compatibility with this mode, however.

About the only other noteworthy points are things we’ve already mentioned: GT 425M Optimus graphics and a large 8-cell battery are definitely appreciated. More impressive is that ASUS manages to fit all of this into a 4.8 lbs. chassis, making the U41JF 0.7 lbs. lighter than the discontinued Dell XPS L401x despite having a higher capacity battery.

One other tidbit I do want to point out is the inclusion of Office 2010 Starter. Yes, you have to put up with some advertisements and you only get "limited" versions of Excel and Word, but let’s be frank: Microsoft Works sucks, so being able to open and use standard Word and Excel files is a great improvement. Or you can just go the route if you choose, but I certainly won’t miss uninstalling Works.

    Besides the MacBook Pro? I'm not aware of any right now; most of the high-end displays tend to come in business laptops, and unfortunately business laptops often fail on the graphics side of the equation. Dell's XPS 15 update is still good, but aesthetically lacking and battery life isn't as high as I'd like (review forthcoming). There are still some decent 1080p 15.6" panels around, but if you're looking for something in the 13-14" range I'm currently at a loss. :-(

    I'd actually consider buying this if it had a decent 1080p screen:( Something around as good as the one Compal used in their 15.6" laptop with the GT425m.

    Jarred: I do think you'll be interested to hear that there IS a laptop with a 1080p screen in a 15.6" chassis for as low as 526 dollars on right now. I don't know the specs or contrast or anything like that, but it's a laptop with Sandy Bridge and no dedicated GPU that does however offer a 1080p screen for 526 bucks. Start upgrading things and the price goes up but you could still get one hell of a laptop for 700 bucks really easily.

    I would LOVE to see how that screen stacks up against the bog standard we're bombarded with. Please do everything you can to get one of those in house configured however you want, preferably with a 2nd Gen i3 or i5 (we've already seen i7 performance plenty) in it.

    The inexpensive Xplorer-9200 probably uses a display much like the 1080p model in the ASUS N53 we looked at a couple months ago; the Xplorer-9300 (Clevo P151HM) on the other hand is probably a decent panel, but it costs a lot more. Anyway, I sent them an email so we'll see if they want to send us some review hardware.

    "If ASUS is like other manufacturers, they have some smarts in their batteries so that they don’t overcharge some cells (and cause them to wear out faster), which would explain the drop in power draw as maximum capacity approached."

    afaik all lion and lipo batteries consisting of more than 1 cell have to be balanced. thats why batteries not only come with two poles, positive and negative, but also with a few extra poles, depending on the cell-count. so every cell can be charged and discharged to the exact same voltage (only differences up to ~0.02v are acceptable).

    i know this because i recently upgraded my rc-car to lipo-batteries and needed a new charger with balancer for that matter.

    so now you know ;)
