Random Bits of Dell XPS M1330 Knowledge

Here are some random bits of information I’ve discovered about my Dell XPS M1330 in the past few days:

  • The issue where, upon resuming from sleep mode, the M1330 will drop from 1280 x 800 resolution down to 1024 x 768, seems o have no fix at this time. I called XPS tech support and they weren’t even aware of the issue (which I find hard to believe, it’s mentioned all over the place). It happens perhaps 25% of the time, and the only fix it to go into the display settings and set it back to 1280 x 800.
  • Upon resuming from sleep mode, the screen will light up as normal, then go black, then come back. This is irritating. The solution (which I found in this forum) is to go into the Task Scheduler (just type Task at the start bar and you’ll find it). Look under MICROSOFT > WINDOWS > MOBILEPC and you’ll see a task listed called TMM. Right-click on it and select DISABLE. This will address the issue.
  • Although the XPS tech I spoke to insisted otherwise, upgrading the graphics driver for the NVIDIA GeForce 8400M GS with a driver right from NVIDIA isn’t possible. Only a driver directly from Dell will work, which sucks because it means I’ll never be able to have the highest-performing drivers.
  • I have a D-Link DIR-855 802.11n router and was having a lot of connectivity problems with the XPS M133o – it would always connect initially, then it would drop the connection…but only for certain types of requests (seemingly). I could ping anything (I ran a ping -t), but no Web pages would load, nor would email. Vista’s “Detect and Repair” thought that the connection was perfect, so it was no help (I suspect it does a ping to check connectivity). This issue was driving me crazy, but after installing the 1.05 firmware on my router, and updating the BIOS on the M1330 to A06, it’s now working fast and stable.

UPDATE: A solution was presented in the comments section: disabling the TMM scheduled task. I did that, and guess what? No more resolution switching. No more “fade to black” effect. Nice!
