New used laptop: Thinkpad T430

I meant to post this ages ago: in early 2018 I got my first Thinkpad – an old T430. Very nice.

I had been looking for my first Thinkpad; an upgrade off a slow Lenovo (non-Thinkpad) laptop, and I thought I might splash out on a new one.

But then I discovered my sister had an ex-work T430 she didn’t want. Sold it to me for what she got it for: AUD $100.

Specs: i5-3320M (2.6 GHz), 4 Gb RAM, 1600 x 900 display, SSD. With a dock (that I’m not sure I’ll ever use)

Some scuffing on the case, but overall it’s in very nice condition. Not sure how old it is, but this model was first sold in 2012.

And I found I could still upgrade it from Win7 to Win10 for free, using the Media Creation Tool.

I added another 4 Gb of RAM.

The keyboard is lovely, but I never did get used to the Fn/Ctrl key locations being backwards from most layouts, so I ended up swapping them in the BIOS.


One oddity after upgrading to Win10: Microsoft Edge was extremely slow to respond to clicks. The solution was a clean Win10 install – via the “reset your PC” feature.

I also found that under Win10, the trackpad would sometimes freeze up for a few seconds, particularly after two-finger scrolling:

  • This turns out to be an issue with the Lenovo trackpad “palm check” feature. Set this to the minimum setting (or turn it off) and it seems to go away. The same problem occurs for some other Lenovo laptops.
  • This can also occur if Trackpad Tapping is disabled – I’d prefer it was disabled to avoid false positive clicks when I’m just trying to move the pointer, but oh well.

But I hope this old laptop will keep me going for a while for my on-the-go computing needs.

Nature strip computer For The Win!

I found a computer on the nature strip; it was enormous, but had a couple of DVD-RWs, dual DVI connectors and USB3, so I figured it was reasonably modern.

When I got it home and inspected it closely, I realised it wasn’t USB3 but eSATA instead, and my hopes deflated. Booting it up showed a BIOS from 2006 and I figured I just bought myself another trip to the council’s transfer station. However, checking out the CPU (Intel i7 920), full-height full-length graphics card (MSI R4870X2) and RAM (6Gb of DDR3) I realised I had found something special. Dropping in a SATA drive that I salvaged from a machine we decided was past it’s use-by date, I built it into a Linux Mint box.

Yet again, the most powerful machine in the house was found in hard rubbish.  It’s twice as powerful as the last computer we bought, and nearly twice as powerful as the most recent desktop machine.  The RAM is a bit light-on, but DDR3 is still widely available.  The TPD (power consumed by the CPU) is 130 watts, which is… a lot.  Not a machine to run in a small room on a hot day.  Add in the graphics card that consumes between 120 and 220 watts depending on load, and a meaty power supply is needed; the one in the case has 1000W written on it, whatever that really means.

At the end of last year I found my local primary school had unceremoniously tossed about a dozen PCs into a dumpster filled with detritus such as broken plastic tubs, desks without legs and out-of-favour books (like a perfectly good Macquarie dictionary). Figuring I could cannibalize multiple machines into a single working machine, I pulled a half dozen monitors and three computers out and loaded them into the car. When tested at home, everything worked just fine. Everything. Confronting the authorities the next day, I was told that the PCs were “broken”, but after some haranguing I got a concession that next time the machines would be donated to a computing charity. As a result of this find I have a three-computer cluster of dedicated Minecraft machines, which now provide adequate performance after extensive tweaking.

Have you found anything good, or would you never take home strange hardware?

Low spec notebooks can’t handle large amounts of RAM

Cathy and I are seeing increasing contention for the grunty computer in the house not dedicated to playing computer games. It’s used for a combination of recreational programming, web surfing and media encoding tasks. We decided to acquire a second, and after comparing the costs decided that the premium for laptop portability wasn’t too great (about $100; in fact that seems to be about the price of the OS we were forced to buy with the hardware). In out usage profile, “grunty” isn’t defined by CPU, but responsiveness which really comes down to how often an arm has to venture out across a spinning sheet of rust. Unfortunately, bottom-end systems (i3 class CPUs) can’t handle our base-level RAM requirement of 16Gb, so yet again a portable computer is the most powerful thing in the house – the new system’s specs are:

Processor: AMD Quad-Core Processor A6-5200 (2.0GHz, 2MB L2 Cache)

25W of power consumption right there. Existing grunty computer pegs its CPU for about ten hours a year, in sustained encoding runs. We weren’t CPU bound, and yet the only way to get that RAM in an i3 lappy was to spend an extra $100 on a Toshiba with worse specs – so we got a quad core.

Memory: 4GB DDR3 1600MHz (max support 16GB)

That 4GB came straight out and was replaced by the most RAM that could be stuffed in there. Existing grunty machine had 8Gb and was paging a lot. Why are web browsers so memory hungry? This upgrade cost $160.

Storage: 500GB (5400RPM) Hard Drive

This came straight out before the machine was even powered up once. It was replaced by a Plextor M5-Pro 128GB SSD; this unit was selected for its fast random write speed, and the common-for-all-SSDs 0.1ms seek time. Back in the day (about ten years ago) I advocated that when building a machine, you should get drives with the fastest seek times and screw everything else, plus all the RAM you could afford – to use as disk cache. How little things change. This upgrade cost $129.

After Linux Mint 12.04 Maya (LTS) was installed (consuming 6Gb) there was 110Gb free on the replacement device. Paging has been disabled due to the SSD write limitations, and tmpfs is used for various directories to further minimise our impact on the longevity of the drive.

Graphics Card: Onboard (Integrated)

The contention for the memory bus is troubling, but at least there’s no extra juice being sucked down to power a fancy-pants GPU. This is not a gaming machine, 2D acceleration is useful, 3D not.

Operating System: Windows 8 64 Bit

That went with the rotating media. We’re going to see if we can boot a desktop machine off of it and still have the OS believe everything is okay. The laptop didn’t like the new OS, saying “Selected boot image did not Authenticate. Press Enter to Continue”, but the solution was to disable Secure Boot.

Screen: 15.6-inch diagonal HD BrightView LED-backlit Display (1366×768)

It took some fiddling for Cathy to figure out how to dim the damn thing under Mint. Turned out the answer was to install the proprietary AMD drivers.

Audio: Dual Speakers Stereo DTS Sound+

If you’re using a laptop for A/V reproduction, you’re doing it wrong.

Connectivity: Gigabit LAN (RJ-45 connector), 802.11b/g/n WLAN, Bluetooth

The Toshiba only had 100Mb, in this day and age! The Ralink wireless adapator wasn’t picked up automatically by the installer, so Cathy got down and followed the instructions off AskUbuntu

Built-In Devices: 1x USB 2.0, 2x USB 3.0, HDMI, RJ45 Ethernet, Headphone-out/microphone-in combo jack, SD/SDHC/SDxC Card reader

USB3 was important in picking the unit, as I’ve seem just how much faster it is. HDMI is necessary for twin-monitor development; MSY had a 21.5″ Full HD IPS on sale for $118.

Webcam: HP TrueVision HD Webcam with integrated dual array digital microphone

I’d just paint over it, but there’s a chance that we’ll have a use for videoconferencing. It stays, but it better mind it’s Ps and Qs or else it’s black electrical tape for it.

Optical Drive: DVD Burner

Yeah, like that’s ever getting used.

Weight: 2.33 Kg

I’m more used to computers that weigh 1Kg, not two and a half.

Dimensions: 56cm (L) x 13cm (W) x 34.5cm (D)

This thing has a widescreen display, it’s freaky big compared by my 10” netbook.

Other observations: the keyboard sucks balls, with the trackpad positioned such that you physically can’t touch-type on it because doing so places your palms on the trackpad, moving the mouse and screwing up your input (I think this is happening because gestures have been turned on; they might find themselves getting turned off again). For some messed up reason they’ve included a numeric keypad, so touch-typing is doubly hard – again with the palms. This thing’s going to find itself plugged into a USB hub with a real keyboard and mouse quite a lot I think.

Anyways, the HP Pavilion 15-E001AU was purchased from MLN for the low, low price of $500. Total system cost was $907, and at the end we had a 4GB lappy stick and a 500GB lappy drive laying around.

TV tuner for Mac Pro?

I’ve been delighted with the secondhand Mac Pro I got last year. It’s five years old, but probably the best Windows PC I’ve ever owned… we sometimes use OSX, and sometimes use Boot Camp to run Windows, and I did end up getting Parallels as well, which is able to boot the Boot Camp partition — this I think is nothing short of miraculous.

Anyway, our other Windows PC is due for replacement. I was thinking I’d wait and see what the next crop of Mac Minis were like, but it looks like I’ve again got the opportunity to pick up a used Mac Pro via the same workplace clearing more of them out. Same age, but (if my calculations are right) double the speed of the current Mac Mini. Given our usage patterns, this is a cheap easy upgrade… particularly if we put an SSD in it.

I’m now pondering: what’s the best TV tuner for it? That’s the main thing I miss about the HP desktop we had that died. (I did try and rip the tuner card out of that to try in the Mac under Windows. It didn’t work.)

So… Mac Pro TV tuners…

I’d prefer dual tuner. I’d want it to work with both OSX and Windows. In fact I’d go so far as to say that this second box will be mostly using Windows, and I’d want this to work with Windows Media Centre.

For a USB dual tuner, the Elgato EyeTV Diversity looks pretty good.

Asking around on Twitter, there was some good feedback:

(Why does Twitter’s embed tweet with “Include parent Tweet” not seem to work?)

It’d be used with a proper connection to a roof antenna, so not concerned about the mini antenna.

But I think I’d actually prefer an internal card, since I really don’t need it to be portable… and installed internally might be more out of the way/better for longevity.

Any good options?

PS. This ancient page talks about some options. Not sure how relevant it is anymore though.

Cleaning up your PC

I was wondering two things about “Snowy”, one of my PCs:

Why was the fan so noisy?

And why did it occasionally stop dead in its tracks? Typically when the machine was busy, and particularly noticeable while playing games. No warning, no graceful shutdown, just power off.

I had been planning for a re-installation of Windows, and started the process when it shut down again.

So I decided to open it up. Checked a few connections. Nothing obviously loose.

Then I looked at the fan. Caked in dust.

Using a vacuum cleaner, a duster and a pen (the latter for poking in to disturb the dust where nothing else would reach) I cleaned around the motherboard, and particularly on and around the fan.

What appears to have been happening is that due to the dust, the fan was having to work harder than usual. And when the CPU got busy/hot, the fan couldn’t cope, the CPU overheated, and something smart in the PC was cutting the power to stop it causing any damage.

Since the cleaning, the fan is not only quieter, but there haven’t (touch wood) been any more sudden shut downs.

Basic Windows setup

I got a “new” secondhand PC for my girlfriend. An off-cast from a friend, so obviously it’s not the latest and greatest, but it’s faster than the box she has now. 500Mhz P3, 192Mb, about 40Gb space over two hard drives. Might see if I can find some more memory for it, but I can live with that. It was running Win98 SE, and was overdue for a rebuild.

Wordprocessing and web were the main requirements. An old computer and basic requirements call for basic software, and old versions in some cases.

So, here’s the setup I did on it:

Found a spare Win2K licence, booted up using the CD and wiped the disks. Installed.

It picked up all the hardware no problems, but later I found it didn’t shut down automatically (went to “It is safe” instead). Made a note to fix that later.

Installed Win2K SP4 and the post-SP4 rollup (aka SP4 and a half). And IE6 SP1.

Then went to Windows Update and got it to grab everything going; well, at least the security stuff — don’t really want the latest bloated MediaPlayer. 45 updates and many minutes later, it was okay. Except for one thing, which I came back to later.

Found a spare Office licence (XP) and installed Word, Powerpoint and Excel. She’s not a geek, so she didn’t need Access or Frontpage, and her email is all web-based, so I didn’t bother with Outlook. Went through the custom setup to ensure minimum bloat (eg no VBA help, obscure file conversion, speech input, that kind of thing).

Put on Office XP SP3, then went to Office Update to see what was going. Stupid thing wanted to install patches for Visio. Switched them off.

Grabbed the typical extras useful for web browsing: Acrobat Reader 5.05 (just before they went stupid with bloat; still obtainable from Flash Player (latest). Quicktime Alternative. Real Alternative. And Google Toolbar for popup blocking.

Also plonked on the latest DirectX. Winzip. AVG Free. This PC will live behind a NAT router/firewall, so I’m not going to bother with a firewall.

Put a copy of Mame32 on there for some light entertainment.

Created a logon for her, and a logon for me. Standard users of course; not Admin. Verified everything works under those new users.

Used Ed Bott’s method for securing IE: Once the ActiveX controls you want are in place, go into the security settings and disable Active X Signed downloads. You have to do this for each individual user, but it solves a major gripe of mine; that IE can install any old crap provided it’s signed.

Went through the services and disabled the extraneous stuff, like Messenger. Likewise checked for any other little applets that decided they should run in the background. Most of them aren’t needed.

Turned on automatic Windows updates. One problem: it insisted one patch needed installing, but each time it claimed it had worked, it hadn’t. Next time it looked, it still needed to be installed. Downloading and running the patch manually showed it had been superseded by something else… but Windows Update apparently couldn’t figure that out. Eventually I solved it by going into the Windows Updates web site and manually telling it to ignore this patch. (Thanks Malcolm for the help on this.)

As for the “Safe to turn off” instead of turning itself off, that was solved by going into the Control Panel power options and turning on APM.

Am considering Paint.Net, but then I’d have to put the Dot Net Framework on it as well. Don’t want to over-burden the poor box.

Ditto Firefox — IE has the advantage of virtually sitting in memory most of the time. Firefox is great on fast machines, but is an extra load on slow ones — as I write this, Firefox on my PC is sitting on more than 70Mb of memory. Sure, I could get Opera or whatever, but if IE is relatively safe (patched, unable to download more ActiveX, most popups blocked, running under non-Admin users, and not being used by idiots), why bother?

Considering adding Java (my Internet banking needed it until very recently, but they just switched to pure HTML, woo hoo!) and DivX.

Anything else I’ve missed before I hand it over? Will it be secure enough?

Old PC getting you down?

It’s been long known that outdated computer equipment could have direct consequences for productivity, by slowing the workers down to the speed of their machinery. But a new survey concludes that it also has effects on morale in offices, causing not just unhappiness, but also more issues with things like eye fatigue, headaches and RSI.

(Hey boss, can I have a new PC?)


So, that shiny new computer I’ve been given and my propensity to save power have combined with boyish enthusiasm with a practical joke to create a very embarrassing situation for the two other contractors I work with.

I normally leave my box locked overnight, shutting it down on a weekend. So a discovery of a week ago had to wait until Monday to play out.

My new computer has a temperature sensitive main case fan that’s ducted – at higher temperatures the fan is cranked up to increase the airflow over the water cooled CPU heatsink. There’s a BIOS setting to set the idle fan speed; the default value is almost imperceptable, the highest is a roaring not dissimilar to a jet taking off (mainly because of the ducting and air being forced through the heatsink – all the turbulance is very noisy) and certainly seems to move a lot of air. Apparently the other guys here discovered this setting, and thought it would be a great idea to crank up the idle fan speed to “stupidly high” while I was away.

When I powered up the box, and the roaring fan started, I immediately went to Dean, the guy who did the swap-over to the new box. Having a CPU cut out because of overheating is not cool; I imagined that the heatsink might have come off somehow. He couldn’t imagine what was going on, and did note that the air wasn’t hot. Opening it up revealled everything in its place.

At this point the pranksters saw that this could escalate well beyond a prank and intervened with an explanation. Whilst I wasn’t put out, other people put the pranksters in their place. So, kids, be careful with those pranks. They could blowback on you (oh, I hadn’t intended that pun!).

Ten years ago…

Yesterday, I bought a computer. With a bit of luck it’ll be ready on Saturday.

As it happens, it’s not quite ten years since I bought my first “new” PC. (Before that I’d used 8-bit computers and an aging 286.)

Just for a little nostalgia, here is part of the advert from the company I bought it from all those years ago, the now defunct Rod Irving Electronics, of A’Beckett Street in Melbourne. This is from the 6th June 1995 edition of The Age “Green Guide”.

The system I bought from them was the Pentium 60 on the right hand side. I’m sure you’ll be impressed at the spec, as well as the marketing. (At the time, the Australian Peso was worth about USD0.60, by the way).

Rod Irving Electronics catalogue from 1995

This computer was finally disposed of in rather spectacular fashion in 2003, though the speakers and that mighty 4x CD player still work (currently stored as spares).

Soundcard problem fixed

Remember my noisy soundcard at work?

Well, the problem has been fixed – by getting a new computer. Naturally, it wasn’t the only reason for an upgrade, but it was the main reason. 😉

But that’s not the impressive thing; the impressive thing has been the upgrade process. It was the smoothest I’ve ever experienced. Old parallel IDE drive out, plugged into new SATA computer’s CD ROM cable; boot OS, copy a couple of directories over, shutdown computer; remove old parallel IDE drive, reassemble box; boot OS, work. And that was it. Must have taken 15 minutes tops – I was expecting two days of downtime or lowered productivity. Every piece of software I need was installed and ready to go, I only had to tweak a couple of preferences. Similar process for all the other upgrades the team has undertaken this week.

So, my opinion of Dean, the guy that organised it all, has gone through the roof. Dean rules. He rocks.

And all because he arranged to not waste my time. What a guy.
