I’ve been struggling off and on with an issue on my Dad’s computer the last month or so. He said that it would occasionally just shut off completely out of the blue. (He also admonished me not to spend much time on it. Unfortunately problems like this are usually the ones that take the most time to solve because they seem random and it’s hard to pin down the cause.) He runs Windows XP primarily (although we have an ubuntu install setup as a dual boot choice.) In the last year the power supply and video card have been replaced for similar behavior. Although it’s been several months since the replacement with little “misbehaving” since. One of the things I did was run a memory test, which came out fine.

Ubuntu 9.04 Jaunty Netbook Remix on an Acer Aspire One ZG5 trackpad issues
Recently I had the opportunity to work on an Acer Aspire One netbook. It’s rare that I get the chance to work on a linux desktop system for a client. Most of my desktop users that I support run Windows (although I primarily run linux on my machines.) I get to do a fair amount of server level work with linux variants, but this one, being a desktop install, intrigued me.
The issue was that the buttons on the trackpad didn’t work. She also indicated that she had tried a usb mouse and those buttons didn’t work either. As I looked at it, I had already spent some time browsing through bug reports getting ideas on what might be the issue. It behaved exactly as she described and so then the real fun began.

What’s the oldest working computer hardware you still have?
This is a good time of year to think about cleaning out your old electronic (junk) equipment and make room for the new. Now, I’ve had a tendency to hang onto legacy hardware longer than I should. (I’m sure I could dig up a working 5 1/4″ drive somewhere and probably a motherboard that would support it.) So, I thought I’d open this up and ask – what’s the oldest (working) computer hardware you still have?

Dell Mini Notebooks – Very Nice
I’ve seen these new mini notebooks and they look VERY nice. They’re about the size of a small book which makes for nice portability. It’s nice to see the small laptop form factor making a comeback. I really hope that this size laptop is around to stay for a while. I have an old Sony Vaio which is not a bad size, but most laptops are just too big to be REALLY portable.
I think this size notebook is an improvement on the concept of the PDA because it gives you more options.

Leaky Capacitors and Computer Instability
Some time back I did an article here about leaky capacitors and linked to some really great photos of a “healthy” mainboard capacitor and “bulging” capacitors. The long-story short version is this… Once upon a time there was some corporate espionage among capacitor manufacturers. Someone had a really good electrolyte formula (the goo inside a capacitor) and the other companies wanted it. Well, what they wound up getting was not the real formula, but a fake. So… any capacitors made with the false formula will be more likely to fail. In fact, it’s as though over time the electrolyte expands causing the capacitors to bulge and in some cases leak. Why is this computer related? Because if you crack the cover of a pc and look there are dozens of electrolytic capacitors on the mainboard.

The Linksys WRT54GL and DD-WRT firmware
I’ve had a couple of small wireless projects lately and have really been having a great time playing around with the Linksys-Cisco WRT54GL Wireless-G Broadband Router and one of the many GREAT 3rd party firmwares dd-wrt. I know, for a couple years I’ve meant to get a hold of one of these little linksys boxes for testing. I had read about OpenWRT and found it an interesting idea. For those that don’t know, the original linksys wrt54g wireless routers were designed based around a customized linux firmware. What made this nice is linksys made the source code available for their firmware which made it a lot easier for others to improve upon linksys’ built in software.

Good USB ThumbDrive – Kingston 8GB DataTraveler
Just thought I’d do a quick post – I’ve had kind of a poor track record in ordering USB thumb drives lately. I ordered one which I absolutely hate… it was about the size of one of those small pieces of gum and didn’t have the proper USB adapter on there so all you do is slide it into the usb port on your pc – the problem is… which direction – well they say it will only work one way and you’ll feel some resistance the wrong way, well I tried it and found resistance both ways so I got down on hands and knees and looked in the usb port to see where the contacts were and lined the stick up with those so I KNEW beyond a doubt I was connecting it the right way. I managed to get it in and thought I was never going to get the thing out. Since then I’ve been using a usb extension cable with that annoying thing…

Replacing a Power Adapter for a Microtek Scanmaker 4800
This is just a glimpse of the kinds of things I get to do day to day… A week or so ago I had a client that had received a used scanner from a friend. The scanner was a Microtek Scanmaker 4800. I was a bit concerned as her pc still has Windows 98 and I recall very many long hours of hair pulling making USB scanners and Windows 98 work years ago. Fortunately though, the driver cd was included in the bag their friend had passed along. The install process went smoothly, but there was one little detail missing.

Nvidia video cards
I’ve been looking at a new video card lately (X-Plane…) And am certain that many people are confused by Nvidia’s product lines of late… Here’s a nutshell idea…. They’re currently using 4 digit product numbers – like 7300, 7800, 8300, etc…. I found this breakdown in zdnets talkback…

Hard drive testing utilities
Windows users know chkdsk, linux users know fsck… users of each MIGHT have heard of SMART. These are different ways of TESTING hard drives. Well, there’s also a utility called TestDisk that looks promising for recovering data… Here’s the clip from their site. “free data recovery software! It was primarily designed to help recover lost partitions and/or make non-booting disks bootable again when these symptoms are caused by faulty software, certain types of viruses or human error (such as accidentally deleting a Partition Table). Partition table recovery using TestDisk is really easy.” It runs under a variety of OS’s and recognizes several different disk formats.
