Eee PC care at 2 years

In November 2007, we bought two of the first Eee PC netbooks available in North America: the model 4G in pearl white, one for me, and one for my wife. My plan was to start the Debian Eee PC project and get Debian working on them both which, thanks to the work of everyone on the team, has been a great success. Fast forward to February 2010, and they are still serving us well. Here is a list of hardware enhancements and issues over the past two years of continuous use:

Battery life

Asus claims 3.5hrs for the model 4G, though I don’t think we ever experienced anything better than 2.5 hrs with wifi in operation. Today, I’m down to something short of 2 hrs. If you consider the Lithium ion battery article on Wikipedia to be accurate, it is typical to permanently lose 20% capacity per year, so this sounds about right for the age of the battery.

Touchpad

The touchpad itself is fine. The buttons are not. They are hard to push and prone to become less responsive after a while, or to fail entirely. I now really have to bear down hard on my left button to make it work. Because the buttons are soldered to the motherboard, they would be hard to replace. Configuring the synaptics driver for tap-to-click is an acceptable workaround. Also, one of the first purchases we made was the Logitech VX Nano, one for each Eee, so most of the time now, we use our mice, falling back to the touchpad only when using a mouse is inconvenient due to space constraints (e.g. on the bus).

Keyboard

After two years of continuous use, both of our keyboards needed replacing. Some of the keys had been pounded flat and needed surgery (rubber springs sliced out of a scavenged Acer netbook keyboard and grafted on) to make them usable again. And aesthetically, the keyboards have really suffered, with a good percentage of the markings on the keycaps partially or completely eroded off.

Fortunately, for $3 plus $10 shipping each, new keyboards can be ordered from a Chinese e-Bay seller. But with the new keyboards, there is still the problem with excessive flex in the keyboard making some keys less responsive than others. I’m considering trying this hack to solve the problem.

Display

I have no complaints about the matte finish displays of either Eee. Both have stood up well. People tell me they don’t care for a 7″ display, but I find it bright, crisp and easy to get along with, so long as you maximize windows and increase font size as needed (e.g. for reading PDF books and magazines). When I really need the extra real estate, I just hook up an external monitor.

Fan

Some people complain about the noise of the fan, from the otherwise silent 4G (due to the lack of a hard drive) and seek ways to limit the amount of time the fan runs. We’ve never had that problem. However, if any plastic bits break off inside the Eee, they will eventually find their way to your fan and get wedged. This has happened twice: once in my wife’s Eee, and once in mine. Disassembly of the Eee to clear the blockage and get the fan running again was relatively painless both times.

Plastic bits

About those plastic bits: In my wife’s case, I think the bit was some extruded plastic from the molding that had broken off. In my case, it was a deteriorating plastic post which was holding the hinge in place. More about this later.

Sound

Unfortunately, the integrated sound seems to be particularly sensitive to heat. During both fan failures, sound cut out. On my wife’s system, it never fully recovered, and now only works on alternate Tuesdays, whereas on mine, after I unwedged the fan and brought the heat down, sound has functioned properly ever since. (Update: see my comments below on power adapters for an alternate theory about what killed sound.) We are waiting now for the delivery of a cheap ($1.42 including shipping, again from China) 3D Sound USB device which is reported to work on Linux. While some users complain about hum with this device, we’re cautiously optimistic that on the Eee it won’t be an issue. If it is, oh well, a buck and a half is a small gamble.

Update: It works! My wife is very happy. Money well spent.

Display hinge

The plastic posts that hold the anchors for the machine screws for the hinge are fragile. Three out of four of these posts in my Eee have shattered, leaving the left hinge to float freely. For the past two days I was distressed about how I could fix this. Based on some helpful suggestions from #eeepc @ irc.freenode.net, I had worked out a plan to rebuild one of the posts with two-part epoxy, sand it and the fractured stub of the post, and use cyanoacrylate glue to affix it to the case. It sounded like fiddly work for which I didn’t hold much hope of success. But this morning, I realized that the plastic in the bottom of the case was still sound, and that I could drop a screw into that hole, and with pliers, line up the anchor on the other side. This appears to work! I’ll handle that hinge with care, but it should do me until I eventually repurpose the machine to some daily use that is less stressful on the hinge than daily travel on the bus.

Update: Sadly, this broke on the weekend. The thin bit of plastic at the bottom of the hole just couldn’t take the stress. I’m planning a second attempt to fix it soon, using sturdier materials.

SSD and SDHC

Some people were initially worried that the limited write life an SSD meant that you needed to take special measures to avoid its premature death, which I have always regarded as a myth. Our 4G SSDs each have no swap space, and ext3 filesystems. At the two year point, there are no problems. I expect our SSDs to outlast the other components.

We did, however, eventually find the 4G to be a bit on the small side. We now each have Kingston 4G micro-SDHC cards for a bit of extra capacity for large media files and for some extra space for the apt cache. I recently priced the Lexan version of this card at $19 for a two-pack at Wal-mart, and these seem to work in the model 4G just as well (which seems to be an issue with this model — not all SDHC cards work).

Memory

We found the 512M that came with the 4G somewhat constraining. Without any swap space (so we could maximize the space available on the small SSD) we decided our systems really needed a memory upgrade. At the time, 2G didn’t seem overly expensive (though I no longer remember the exact price) so we splurged on 2G for each system, even though that was probably more than we needed.

Power adapter

When I first wrote this article, I forgot to mention the power adapter. The model 4G uses an unusual 9.5V power adapter for which it is hard to find a generic replacement. This unit is prone to fail in two places: in rare cases, (one out of 6 units that I have in some way assisted with: 3 of them mine, 3 belonging to others,) it will break at the wall plug end. The plug swivels into the unit for easy storage, but this adds a point of failure. More commonly, (in 3 out of six of the units,) the wires at the netbook plug end will fray due to stress on the non-angled cord, leading either to no connect, or to a short. In fact, since in the case of my wife’s adapter, the netbook end of the cable shorted, making the cable heat up and the system spontaneously shut down after a little while, we can’t say for sure whether the overheating of the Eee took out integrated sound, or whether this short did. On the one hand, I know for certain my own system, which never suffered a short, has responded to overheating by making the sound flaky, but it has never taken out sound completely. On the other hand, shorting the power cable can’t be very good for the Eee, so who knows, maybe that’s what ultimately killed my wife’s Eee’s sound.

This is where it helps to have soldering skills, or a friend who can do the repair for you. In my case, it was the latter. While I was waiting for a replacement adapter I had ordered, we also found on eeeuser.com part#s for replacement plugs and sleeves from Digikey, total cost $20 including shipping, 10 pieces each. Cutting off the bad plugs on three units and attaching the new was a quick, straightforward operation, and succeeded in two out of three cases. Having carefully checked the failed repair, we deduced that the failure in that unit was at the wall end, and we judged there was nothing further we could do to try to save it. Even the unit that had previously shorted was returned to perfect health and has been in operation trouble-free ever since.

Conclusion

After over two years of continuous use, the model 4G has held up well for a $400 system. We definitely feel we have received our money’s worth of value over that time. All of the problems we’ve experienced so far have been fixable at very little expense, and we expect them to last at least another year before we seriously consider replacing them. In the next several months, I plan to order a high capacity 8-cell 10400mAh battery for my own system so that I can enjoy a 5-6 hr run time. The purchase will be roughly $55 including shipping, the most expensive purchase for my system to date, but still well worth it to extend the 4G’s lifespan for another year or more.

  1. Same experience here in EU. Touchpad buttons broke, screen hinges look wobbly, added extra RAM. But I did not have the fan or heat issues – I just removed the fan. When a fan gets stuck it actually generates extra heat, so these puppies should run just fine entirely without a fan and thus with no moving parts. Mine does for a year and a half now.

    It has been a great purchase.

  2. Hi there,

    I’m sorry that my reply is a little bit off topic… but:
    Thank you very very much for all the time and work you put in the Debian Eee PC project!!! Of course a big thanks to all other contributors!
    I bought a eeePC 901 (August ’08), and so far, it’s still working without any problems.
    But the best thing is, I started with a 6h battery life without wifi, and a 4h battery life with wifi enabled (2.6.29 debian kernel).
    Thanks to the latest kernel in sid and the eeepc-acpi-scripts I got a boost from one hour with wifi in use. That means, without altering any hardware I have 5h wifi use now! That’s just amazing!

    Cheers
    Strahler

  3. Thanks for working on the EeePC project, my EeePC 701 has been running Debian well since I first bought it (which was when the 901 came out and the 701 was cheap).

    I have an 8G SD card permanently installed that I use for swam among other things. If the swap does kill it then I can buy another one – I’m not going to risk having swap kill the internal storage. So 512M + swap has been bearable for me.

    I mostly use mine for emergencies, so I carry it a lot without using it. It seems pretty solid as I haven’t had any damage of note.

  4. I’ve an EeePC 900 with 20 GB in two SSDs. I kept the 4 GB untouched, repartitioned the 16 GB SSD into two and installed Ubuntu there. The 16 GB SSD died after about three months of usage: I started getting read errors from the blocks containing the ext3 journal. I did one dist-upgrade between Ubuntu versions which may have increased the amount of writes performed on the disk.

    I’m afraid to risk another ext3 filesystem on the replacement 16 GB SSD, even though this means unclean shutdowns result in me having to wait for fsck on boot.

  5. A quick thanks to all of you users for helping the Debian Eee PC project be as successful as it has been. As I’ve pointed out on this blog more than once, Asus continues to release a huge number of new models, each with new hardware and new challenges. We simply couldn’t keep up without all of your contributions! The wiki undergoes daily revisions, many of them from you, as we strive to keep it up to date with everything we know, not only about the newer models, but about changes to the software in Debian for new and old alike.

    By the way, please note the additions above about the power adapter. This had completely slipped my mind when I first wrote the article, and is a notable weak point for this model. I’ve examined some adapters for later models (e.g. the 900 and 901) which now have angled connectors. They seem to be holding up a lot better than the model 701′s adapter.

  6. Marius, the quick death of your SSD means it was defective the day you bought it. I wouldn’t worry about ext3 at all on the new SSD. Your risk now of data loss running a non-journalling filesystem on the new SSD is far higher than the virtually non-existent risk of damage to your SSD by ext3. I speak from not just my own personal experience, but also as one who has talked to hundreds, if not thousands of Eee users over the past two years, many of them with models with SSDs, and many of those using journalling filesystems (this seems to be the rule, not the exception).

    p.s. Did you read the article about the myth of limited SSD writes I linked to above? That was a real eye-opener for me, and is why I no longer worry about this, along with the preponderance of evidence backing up these claims from the many users I have talked to about it.

  7. Marius, I wasn’t satisfied entirely by my first answer, so I went looking specifically for a dissenting point of view to weigh against my assurances that you need not worry:

    http://www.storagesearch.com/ssd-slc-mlc-notes.html

    It may be that in the case of the model 900′s MLC-based 16G flash drive, there *is* something to worry about, according to this article. But keep in mind the article talks about max write throughput because they are concerned with SSD in servers in data centers. It’s highly unlikely you’ll come anywhere close to that kind of demand on a netbook.

    That being said, 3 months is still far too soon, so I stand by my assertion that your SSD must have been defective to begin with. I can’t imagine the difference between ext3 and a non-journalling filesystem made a significant difference. The fact that the problem showed up first in your journal blocks is no big surprise, and is in no way an indication that they the writes to the journal “wore a hole in” your SSD, as any existing flaw would statistically speaking tend to show up first in blocks that were being actively written to, (e.g. the journal blocks,) yet wear-levelling would ensure that no one physical block on the SSD was written to more than any other.

  8. I bought my Eee PC 701 4G back in Easter 2008 and have loved it. This article was interesting for comparing my hardware experience against. I’m currently experiencing the same mouse pad button problem, using double taps now to avoid using the left rocker switch. I did get a handy mini usb mouse from a Novell training course that works great with the EEE pc too.

    At one point I believed the internal SSD was dying as the stock Linux was going flaky, but I’ve since reinstalled with Eeebuntu and determined it must of been the install.

    I can’t be sure, but I believe my screen is dimming, it just feels somehow darker then it used to, perhaps the lamp isn’t reaching the same temperatures? Otherwise the system has been working great, though it doesn’t get as much use as I take it your two units do.

    I’ll have to try DebianEeePC on it sometime soon.
