HP Mini 311 — Power Requirements

As a corollary to the battery life tests, we also performed measurements of power requirements using the AC adapters and a Kill-A-Watt device. These numbers are only accurate to the nearest Watt, so a difference of 1W (i.e. from rounding) could obscure more than a 10% actual difference in power requirements. Also note that things change somewhat when you switch to DC power, so the battery life tests are a better indication of true power requirements.

System Power Requirements - Idle

System Power Requirements - CPU

System Power Requirements - Graphics

As usual, we see most of the battery life results reflected in our power measurements. At idle the Mini 311 uses 9W compared to 8W for the other recent netbooks. With the CPU under full load, the power draw increases to 17W while the other netbooks range from 12W for the ASUS 1005HA up to 15W for the M1022. The ASUS is obviously more effective at conserving power with the CPU under load. In our graphics test (essentially full load as 3DMark will stress both the CPU and GPU), the Mini 311 consumes substantially more power than most other netbooks, but that's due in large part to the fact that the ION LE (9400M) graphics are pretty much an order of magnitude faster than the GMA 950.

    I think a more fair comparison would be to mention all 3 tiers: netbooks, netbooks with video acceleration and CULV laptop. Netbooks have tempted me for a long while but the lack of ability to watch practically any video have long been a turn off from them.

    The ION netbooks are something like $100 more over a netbook without video acceleration. That $100 gets me the ability to watch youtube, hulu, 1080p H264 content and play games like plants vs zombies, WoW or Quake Live. Then for another $100 more I can get a laptop that can possibly do the same but have better battery life, build quality and start office faster? The $100 more is seeming less appearing, especially since it is a non-primary system.

    It seems like an interesting trade off, a weaker GPU and more powerful CPU (CULV + 4500MHD) or a strong GPU and weaker CPU (Atom + ION). The ION is defiantly a stronger GPU than the 4500MHD but I’m interested as to how the balance of CPU/GPU will play out in benchmarks for reasonable games.

    Also, if you buy a mini 311 with Windows 7 then it comes equipped with the full ION. Granted that ION LE really IS a full ION with the DX10 disabled through drivers but it can be enabled either through a BIOS hack or forcing full ION drivers. The Windows Experience Index score for gaming jumps from 3.9 to 5.4 I'm curious how that plays out (311+full ion vs timeline for "light" gaming).

    As for video playback I have no idea if the 4500MHD is any good for H264 decoding. All I’ve heard about it is from forums or comments and I would really appreciate if there was a more definitive source (anandtech) discussing the matter. I glossed over the flash 10.1 article and it would seem that either are fine for youtube or hulu but what about videos we acquired through other means?

    And talking as a "typical" anandtech-reader/power-user type of guy: The ion is more interesting over the 4500MHD because no apple laptop comes with a 4500MHD but they do come with a 9400M.

    4500MHD provides enough GPU acceleration of x264/H.264/Flash decoding that when combined with a CULV CPU you can easily watch 1080p videos.

    The real comparison is Acer 1410/Gateway EC1435u (essentially the same thing) vs. the HP Mini 311. All are ~$400 base price, with a slight advantage in specs (i.e. RAM) to the Acer/Gateway CULV laptops.

    I can't say for sure how the Celeron SU2300 stacks up to the Pentium SU4100, but half the cache and 100MHz should mean it's about 80-85% of the performance. That should still be enough for video decoding (I'll verify with Flash 10.1 on SU4100 in the next couple days).

    For graphics, GMA 4500MHD is about 1/4 the gaming performance of 9400M, but Atom really holds 9400M (ION) back it seems. If the 9400M can only run at ~1/3 it's regular gaming performance because of CPU bottlenecking, we have a real fight. If it's more like 1/2 speed, it's not as close.

    I'll be looking at all of this in the next week or so....

    The HP Mini 311 is multitouch-capable. Yes, the Windows 7 models ship with a driver that inexplicably does not recognize multitouch gestures, but if you install the following driver, they will work:

    You may experience an issue with the function of the left touchpad button being unset from "Click", causing some issues after you wake up from hibernate, just make sure it is set properly. HP should really release a proper Mini 311 ALPS driver for Windows 7.

    Yeah, it sucks that some idiots decided that WE would want glossy LCD screens for our portable computers. *I HATE THEM*.

    But there are notebooks with WindowsXP & Windows7 with excellent matte screens.

    They are called THINKPADS. Some of the cool-looking, lower end SL series has non-glossy screens. And the other series: R / T / X / W come with matte screens by default (Some are/were optional gloss).

    So starting at about $550 (SL) or a typical SL / R with core2duo at $600~700 are matte screens.

    I love my ThinkPad, and the screen was the #1 reason I bought it for $650. Many of my friends buy them now because of the screens and of course the quality. Something that HP can't touch.

    BTW: I also like netbooks... for $250~300, willing to deal with the glossy. But it looks like a ThinkPad Netbook may come out and it has glossy :( (rumored)

    FWIW, the Asus Eee PC 1000HE has a matte screen, though its case is as glossy as any of them (i.e., a fingerprint magnet).

    ThinkPads are marvelous piece of technology. Definitely untouchable by competition. But costly also!

    dell (and afaik hp) buisnes-lineups also offer matte sceens, though at least in the dell vostros, they arent that great considering viewing angles, contrast, colour.

    The HP mini 311 uses DDR3 not DDR2 as you guys have stated in the specifications table.

    Sorry... typical cut/paste typo. :)

    Lots of talk between comparing the Acer 1810 to the ion platform.

    You can get the 399 dual core celeron CULV for 399 in the acer timeline 1410.

    The HP ion platform vs the Acer celly CULV platform is a no brainer comparison, as they are both 399.


    Acer celly CULV is by far the best value in the netbook space atm.
