Still trying to fix my T430s' stability issues
My 6-day-old Lenovo Thinkpad T430s is able to cope with a lot of load generating quite some heat on the components for about 10 minutes, but eventually a blue screen appears. I use the PassMark BurnInTest now, since installing MS Office 10 no longer necessarily results in a blue screen.
I ran a 1 hour, 2-pass memory check with MemTest86+ (booted from USB), but no errors were reported.
The T430s maintenance manual pointed out that some extra diagnostics tools are available at http://www.lenovo.com/diags. Tried installing the hardware and memory tests, with little hope of finding anything.. It broke my Lenovo Solution Center (with the diagnostics panels) with no way of bringing it up and running again. Since I wanted to enable system restore (and disabled it because it is one of the steps for optimizing an SSD-based system) and that didn't work either, I opted for a restoring the Lenovo factory system image for a second time. (Let's say this is a dress-rehearsal for when the the Lenovo engineer pays me a visit, next Friday).
Once the system was re-initialized with the factory image I started tuning it and installing all updates. Here's what happened:
As always, decided against installing all bloatware (Norton, etc).
Noticed that of the 140 GB available on the primary disk, over 12 GB is already taken up by software and 18 GB by the OS. That's a lot, no?
Uninstalled Office (I have a more complete version than the pre-installed image)
Attempted to uninstalled Norton Internet Security --> a blue screen + reboot
After reboot and logon, walked up to the TV to watch a news item. Came back in time to notice a new blue screen while nothing was happening on the machine. (we're getting used to this)
Managed to uninstall Norton Internet Security (requires a reboot)
Downloaded Firefox via IE9, chose to "Run" the installer --> a blue screen + reboot (decided to install FF later on..)
Installed SpeedFan and configured logging of the ACPI temperature (there is also a feature to have the current temperature shown at all times in the taskbar)
Started Lenovo System Update 4 (took a very long time to load + requires an update to the program itself, first) and launched the download and installation of all available updates (ACPI temperature peaking at 66°C at some point). As experienced previously, System Update forces a reboot of the machine after installing the critical and recommended updates. Launched System Update again to process the optional updates. (ACPI temperature stays in the 55-65°C range most of the time). This time, System Update asks if it is OK to reboot (we say, yes). Startup is slow (updates happening in the background, for sure) and after logon, Windows Assesment Tool is briefly seen in cmd-window.
Started Windows Update, changed scheduling settings to 'always download, but let me choose when to install'. ("Check for updates" requires an update to the tool itself). As seen previously, when installing the available system updates, a blue screen appears but before the Windows logon screen is shown there is some Windows Update activity going on.
Launched SpeedFan and noticed ACPI temperature was close to 70°C and the two processor core temperatures slightly over 50°C (SpeedFan calls this "hot") Lots of CPU usage going on according to SpeedFan while no other programs are started. Only after a few minutes CPU usage flatlines and temperatures drop (--> what is this? nothing remarkable to see in the Processes tab of the Windows Task Manager)
Windows Update claims nothing has ever been installed so we launch the procedure again: it continues with "installing update 18 of 38"... with ACPI temperature mostly over 60C. During update 31 and 37 the processor core temperatures go over 50C. Windows Update finishes with 38 succeeded updates (no failures in the update history) and requests a restart. Before logon the update progress is shown. After logon it takes a very long time before the desktop appears... (this is new). Eventually I decide on shutting down the machine, starting in safe mode and restart in normal mode.
Windows Update amazingly reports succesful updates only. I launch the procedure to install the optional updates. (ACPI temperature breaches 70°C barrier and processor core temperatures go well above 50°C at certain points in time.) Eventually I restart the machine to have the optional updates take effect. (it's been awhile since we had a blue screen, btw)
Meanwhile I decide also to log the processor core temperatures to a file with SpeedFan. I'm still not sure what temperatures are acceptable, btw. A quick search on google seems to reveal to 50°C is half of what a processor should be able to take. (This needs more looking into).
Installed Firefox. Installed Windows Security Essentials. Performed a quick virus scan which took about 12 minutes to complete. In the meantime processor core temperature stayed remarkebly cool (< 30°C). Installed three new updates in Windows Update.
Installed the Intel SSD Toolbox and ran the features System Tuner, Intel SSD Optimizer (intel recommends to run this on a weekly basis) and Quick Diagnostic Scan. (I forgot where on the web I learned about this program..)
Ran a succesful BurnItTest for 15 minutes with all tests enabled except for Optical Drives, Printer, Video and 3D Graphics (I will try these later). ACPI and process core temperatures stayed very low.
So with all the updates and optimizations completed, the system becomes a lot more stable. Out-of-the-box it is very unreliable and requires quite some effort to fix.
