Not what you want to see on a 6 week old Thinkpad

I was chuffed to bits to get my new Lenovo W500 Thinkpad a month or so ago. I put Windows 7 64bit on it and with an Intel Duo Core T9400 processor, 8Gb of RAM and 500Gb 7200rpm disk I was looking forward to some awesome performance. And to start of that is exactly what I got. I installed all the newest version of the Lotus stuff, Notes 8.5.2 with embedded Sametime 8.5.1, Symphony 3, Domino 8.5.2, Quickr 8.5 etc. I also added some basics like Firefox and VLC Media Player.

After just a couple of days I had the machine pretty much ready to replace my old T61 as my main customer demonstration machine. Except for one thing. Every now and again the machine would seemingly just lock up with the hard disk light on permanently. Sometime it would recover and sometimes it would require a hard reboot. I took to starting Resource Monitor in Disk mode as soon as the machine has booted to see if I could catch the culprit. You might think that my immediate reaction would be to blame Windows 7, but that was the last thing I was thinking. Since most of the Lotus stack that I had installed were builds and betas rather than gold releases my first guess was that there was a bit of dodgy code in there causing the problem. But some basic troubleshooting showed that they were in the clear. The problem sometimes occurred when nothing "unofficial" was loaded. I could even reproduce it in safe mode.

There seemed to be no rhyme or reason to the hangs. Sometimes it would go hours or even days without an issue but I couldn't trust it to use in front of customers. It was very frustrating having this Ferrari of a machine but not being able to know when it would freak out. Many people point to the indexing and pre-fetching in Win7 as being possible causes but I have had no problems on my home PC which is Win7 32bit so I was sceptical that this was the cause. It also gradually became apparent that even though the disk light was permanently on there wasn't that much disk activity going on, but the disk queue length was shooting up to 50 or 100. This would imply that two processes or threads were squabbling over disk access - but I could find no evidence of what they were. There was no fragmentation on the disk and CHKDSK was coming back clean.

Then out of the blue yesterday this error started appearing.


So it turns out that the problem was a failing disk drive. Not something I would expect on such a new machine. Hitachi doesn't publish a Mean Time Between Failure (MTBF) for the Travelstar 7K500 but it just goes to show that MTBF does not mean how long a drive will last but rather the average. So be warned and never be complacent. Drives can fail at any time. So make sure that you have a good backup. Fortunately I backup my important data to multiple locations (Home Network, Backup Thinkpad) and my really important data (customer presentations) to Lotus Connections Files/Lotus Quickr Places. So it will be very straight forward to rebuild this machine when my replacement drive arrives.

Grayed out hard disk password on a Thinkpad

Every 3 months or so I have what I call password day. This is when all my corporate passwords expire and I need to change them. Despite most of IBM's internal services being authenticated against our intranet ID and password, I still need to manually change things like OS Passwords (two Windows and one Ubuntu clients), VPN, Boot up and hard disk passwords, Blackberry, Sametime, Activities, FTP and a few others relating to non standard sites and services.



Whilst this is quite irritating to have to do, it is a necessary evil and normally quite straight forward. But today I hit a snag I haven't come across before. When I went to change my hard disk password in the BIOS it was grayed out. This was especially annoying because I had changed my power on password successfully. The last thing you want is to have two different passwords on boot up.

My initial thought was that it must be something to do with the supervisor password - but it wasn't enabled. Turns out that the problem was that the hard disk password was set on a different machine, a Thinkpad T60p but I had upgraded to a T61p. As luck would have it, I hadn't got round to returning the old T60p so I could swap the drive back - remove the password and then put it back in my new machine and pop the new password on. I don't know what I could have done if I had returned the old machine. So a warning to Thinkpad users - it is incredibly handy being able to use the same drives across different models - but if you are transferring a drive then remove the password first - otherwise you might find that you are stuck with it!

Jumping cursor when typing on Thinkpad

I have been suffering from a most infuriating problem for the last few months. Every now and again when I'm typing my cursor will jump to the beginning of the line. Since I don't touch type I spend quite a lot of time looking at my clumsy fingers and not at the screen so when this cursor jumping happens and I don't notice it can cause carnage to my document. At other times it was causing a seemingly random word to be selected and as I continued to type would overwrite it. As you can imagine this weird behaviour started messing with my head.

Having worked in IT Support in a previous life I am well aware of the need to find a reproducible set of circumstances in order to trouble shoot a problem. Since I spend most of my life in my beloved Lotus Notes client that was where I first spotted the problem. My initial thought was that it could be a bug in the editor since there had been loads of improvements to it in recent releases (drag and drop stuff mainly). However, it didn't take long to spot the problem happening in other applications including Firefox and even Notepad. With my support head on I might have suspected "Finger Trouble" but even though my typing is not great it isn't that bad.

However, I just had a stoke of luck. For no particularly good reason whilst in an web based editor I just happened to tap my Trackpoint and witnessed my cursor moving to the beginning of the previous line! But that is dumb - since when have trackpoints behaved like mouse buttons? Well after a bit of research I found out that this behaviour is called "Press-to-Select" and can be configured in the Control Panel/Mouse. I have been using Thinkpads for 13 years and I am sure that it has never been turned on in any of my previous machines - I wonder why the default has changed to on now. Whatever, at least I understand what is happening so now I need to decide whether to turn it off or to take advantage if it.

From the Trackpoint tab in the Mouse menu you can configure your trackpoint.

Ticking enable Press-to-Select allows you to configure that particular function.
