HP Mini 5102 Battery Life

As mentioned earlier, we've got two batteries: the standard 4-cell 29Wh and the upgraded 6-cell 66Wh. We've run tests with both batteries, and we also tested a two use scenarios with the smaller battery and the Crystal HD chip. (We didn't want to run all the tests with the Crystal HD and the larger battery, as that would require another day or two of waiting for the battery to run down.)


The smaller battery sits flush with the chassis while the 6-cell battery is a bit thicker and will raise the rear of the 5102 about a quarter inch. It will also add a couple ounces to the weight, but the 5102 is still very portable. Here are the battery life results.

Relative Battery Life

Battery life is on the lower end of the Atom spectrum. With the 29Wh battery, the 5102 manages just over two hours of video playback, but that goes up to nearly six hours with the 66Wh battery. We ran a couple quick sanity checks with the Crystal HD decoder installed and found that while CPU use dropped, battery life doesn’t improve thanks to the chip using more power. Battery life dropped 7-9% in the two tests with the BCM70012 installed. Idle battery life tops out at 4.25 hours with the smaller battery, and improves to 9.25 hours with the 66Wh battery.

Put into perspective, though, even the larger battery life figures are nothing special. ASUS manages to get nearly as much battery life with the 1001P and a 48Wh battery—better actually at idle. ASUS has traditionally done a good job at optimizing power draw on their netbooks, and there’s a big gap between the 1001P/1005PE and the rest of the N450 netbooks. The 5102 places just ahead of the Samsung N210 but slightly behind the other offerings.

    The machine itself looks nice. Very enterprise class looking (event if not performing). And its nice to see a good keyboard and build quality in a netbook.

    But the Atom is just so bleh. I am really looking forward to Bobcat, in hopes that it leapfrogs the Atom (which should not be too difficult).

    Seems a bit outlandishly priced for what is, essentially, the same hardware you'd find in a $300 netbook. For sure, slapping the HP brand on it doesn't add $100 of value to it, any more than slapping a fruit on it would give it a $200+ rise in value.

    Hey, netbook manufacturers, here's a clue! If you want to charge $400+ for a 10" netbook, it had better come with a dual core atom AND 2GB of memory. Otherwise, there are far too many alternatives out there that will attract my attention first.

    Gigabit ethernet and 7200RPM hard drive are notable upgrades over almost all netbooks.

    2GB of memory would be awfully nice though.

    I bought one of these for my girlfriend for her birthday and I'm glad I did. I would have gladly paid more for it. The build quality and keyboard alone are worth the $100 extra. The keyboard is not only very well laid out, but it's spill resistant. The chassis is constructed of metal instead of plastic like on every other netbook. HP also bundles its ProtectTools security suite software which, I think, is a first for a netbook. Combined with a 7200 RPM hard drive and gigabit ethernet, this netbook has all the features I would expect from an HP ProBook but with netbook performance.

    Jarred, does this little guy have a hardware TPM module for use with BitLocker?

    With the increasing number of data-security regulations hitting all facets of business, I'd really like to see a netbook sporting this feature, but I've yet to unearth one. Something cheaper than the typical $1500 "executive class" 12" ultraportable would be nice.

    No TPM Module, no. Sorry. As CK804 pointed out, it does have HP's ProtectTools, but that's not the same.

    "...what would be awesome to see is something with the Mini 5102/5103 chassis (make it 12.1” if you have to), only put in NG-ION and a 66Wh battery and ship it with 2GB RAM and Windows Home Premium. If they can make that and keep the price of the laptop around $500, we’d have an awesome little multimedia device."

    Jarred, I think that "awesome little multimedia device" already exists:

    Beats the N550 for performance, barely bigger/heavier than a 10" netbook and priced around $525. Definitely worth a look IMO.

    I own a 5102 (a red one with the 768p screen) and while I like it very much, I agree with most of the points in this review. I also want to chip in my experiences:

    The glossy plastics. The review points out it shows fingerprints and smudges, but I found that it also picks up scratches and marks very easily. My 6 month old machine already has marks on the bezel from the keyboard. Both sides of the keyboard deck (where it joins with the alloy base) also picked up a small vertical crack near the enter/caps lock keys - a common problem I later learned.

    The soft touch coating. On my 5102, the coating around the edges are coming off - not from any abuse, just from taking it in and out of a case. I guess it's less obvious on a black machine though.

    Fan noise. Actually if you are in a quiet room, the fan can get very annoying if you start playing HD video. It spins up even for regular web surfing on battery power (it could be the N470 vs the N450, but I doubt it). There doesn't seem to be quite enough vents on the base.

    Hit and miss Flash acceleration. It seems to work when it feels like it, or when driver and Flash versions are in alignment, or whatever. Adobe suggests turning on Aero, which I do (Win 7 Pro), but it still doesn't seem to work any better.

    Overall I find the little netbook a good mobile counterpart to my i7 desktop (the 768p screen really helps, as does 2GB of RAM), though if I were buying a 10" netbook now, it would be hard to turn down the cheaper yet similarly specced Asus 1005PR.

    Hi Jarred,

    Thanks for the great review on this somewhat outdated netbook. I was shocked to see the performance virtually unchanged between the resolutions on the internet video sites. Is there some ram bottleneck that Flash 10.1 is imposing that isn't seen with normal video playback? With only 1 gig on a Win7 OS I could see a HDD caching issue that would cripple the performance like you see and this could also account for the near identical performance between the difference resolutions (as the limitation is the HDD and not the crappy Atom).

    I would be extremely interested to see if the numbers change with a simple swap out to 2 gigs of ram. My buddy just upgraded from 1 to 2gig and has said the user experience is vastly better when any type of even simple multitasking is performed (older Atom Eee PC running XP).

    One other test I'd like to see (the main reason my buddy upgraded to 2 gigs of ram) was Skype performance. He's Canadian and keeps in touch by Skype but told me it was all but useless on the Netbook due to horrid performance. Something simple (and cheap) like the Crystal HD decoder would be a huge upgrade if it made Skype usable.

    Thanks again for the great review!
