Battery Life

HP's engineers seem to have short-changed some of the hardware itself in the Folio 13, but those sacrifices (along with sacrifices in form factor) were made in an effort to cram as large a battery as possible into the Folio 13. Indeed, it does include the biggest internal battery of any of the ultrabooks we've tested; the Acer TravelMate's battery is bigger on paper but it sticks out of the chassis slightly, while the Alienware M11x R3 can't really be classified as an ultrabook.

Interestingly, despite having a bigger battery than much of the competition, HP's Folio 13 is only able to provide middling efficiency. Battery life isn't poor by any stretch of the imagination, but ultimately the gamble doesn't seem to have paid off as much as HP would've liked as it's clear there's still some optimization that needs to be done.

Heat and Noise

Another area where the HP Folio 13 benefits tremendously as the result of HP's engineers willing to go a little bit thicker than the competition is in its cooling system. Noise even under load is a fairly quiet whine, and the system does a good job of keeping the i5 running frosty.

Having gotten used to seeing systems running in the 80s and higher, it's refreshing to see the Folio 13 only peaking in the mid-70s where full-sized notebooks tend to hang out. That said, I'm still not thrilled with the idea of having the fan intake on the bottom of the ultrabook (or on any laptop, really). As systems designed to be as light and portable as possible it stands to reason these are going to be used on laps most of the time, and while HP smartly positions the intake near the back and center of the bottom of the notebook, it still seems like this could cause problems. I feel like there has to be a better way to turn ultrabooks into true laptops.

    So it has a low end CPU, only one memory slot, a 1366x768 screen, HPs bloody AWFUL touchpad, Intel 3000 graphics.

    That sounds like par for the course for HP. Although the one memory slot thing is especially odd. Nothing else is significant. I would never buy an HP laptop with their all-in-one touchpad.

    It's so bad that even if somehow the rest of the laptop was great (it isn't) I wouldn't consider it.

    You write

    "HP's engineers took a look at Intel's ultrabook spec and, rather than see how small they could get their design, opted to see just how much they could pack into the spec."

    and then

    "HP has strangely opted to be much more conservative with speccing their ultrabook than other vendors have"

    and also

    "Ultimately, though, the Folio 13 is rather tame for an ultrabook, all the more perplexing since other vendors were able to cram more power into smaller designs."

    It seems to me like your first line is not based in reality, but that they rather opted to see just how much profit margin the can get away with.

    Look at the size of the integrated battery, ports available, and the quality of the keyboard compared to other ultrabooks.

    Yeah, this machine really is a puzzling design choice.

    I've long lusted for the "RAZR Maxx" of Ultrabooks. Take a thin machine and fill it up with battery until it is about the thickness of a "non-thin" machine.

    But HP managed to tank efficiency enough that it doesn't matter. Quite disappointing.

    Why do you keep mentioning the battery? According to yourself it does not deliver.
  • JNo - Tuesday, April 17, 2012 - link

    I concur, there's a lot of contradictory (and therefore confusing) statements in this review Dustin. Your main positives seem to be the keyboard and a 'boxy' design that isn't leveraged for other benefits. You then say it's your favourite ultrabook to date along with the Dell whilst complaining about all the shortcomings. The reasons for it being favoured seem thin on the ground and at odds with the rest of your tone.

    The reasons to favor one laptop over another almost always come down to the feel of the system in actual use -- and I'm not talking about speed and performance. I too think the boxier design with deeper key presses is a good thing -- the ultra-thin wedges on other ultrabooks leave the typing experience severely compromised. The rest of the stuff HP did is certainly "deviating from the norm", but unfortunately much of it is in a not-so-good way.

    Single-channel RAM probably only costs 5-10% performance at best (e.g. in graphics tests where IGP and CPU are being pegged), but when a smaller laptop can have two SO-DIMM slots there's no good reason for the change. Locking down the CPU is okay, as the i5 ULV works well enough, but was that necessary? The larger battery on paper should be great, but it fails to deliver (likely from lack of careful power tuning optimizations).

    Despite the above, the pricing is still reasonable compared to the competition. I'd love a better display (as always), but the Folio runs cooler and quieter than other ultrabooks and the keyboard is more comfortable to type on, with most other areas being more or less "equal". So yes, that makes it a "favorite", but as noted in the conclusion it's still flawed.

    Can i make a request? I have noticed from other sites that both batterylife AND performance fluctuates wildely when notebooks/ultrabooks are run off battery instead of mains....

    From what i can tell most of your tests come from the mains to test absolute best case scenario performance..where as in most cases that form factor is going to be used on the move, so the most relevant benchmark/gaming scores are going to come off battery power, not mains.

    I have noticed that Intel 17w chips perform SIGNIFICANTLY worse when running off battery compared to Mains...likely AMD also, would it then be possible to include in the same graphs the benchmarks/gaming score from running off the deviced battery so readers can see the REAL performance whilst out and about...i just don't think the performance measurements are representative for the scenario it would be used.

    I enjoy your reviews by the way ;) Thanks.

    Jarred Walton recently tested an AMD based notebook which showed gaming performance does not deteriorate on battery power compared to intel.
  • french toast - Wednesday, April 18, 2012 - link

    The point im getting at, and somewhat backed up by what you have said, is that intel iGP is terrible when running off a battery in comparison to AMD.

    What people think they are getting and what they actually get in real world are not the same things, you don't but a laptop to have it plugged into the mains, they are designed to be carried around..i just think it would be more approapriate to test with and with out battery in the same chart...its more accurate...other websites do it.

    I will wait a while if i don't get noticed down in the comments section i will email in with a request, would be really great if Anandtech could do this IMO.
