If you have an Dell Inspiron 640m or e1405, and the screen flickers off and on when you disconnect it from the AC power and it is running on battery, it seemsthat downloading an older Intel graphics driver, rather than the latest one from the Dell web site might fix the problem. Here is a link to notebookreview.com that discusses the problem; here is the link to the older driver from Intel; and, here is a link to older drivers from Dell (I downloaded the one from the Intel site). Of course, only time will tell, and I have no idea if this will work for your notebook, but so far it has worked for mine. You may have to play a video for the symptom to show up – it seems that if I did not play a movie, and just disconnected it from AC, the screen stayed fine, but if I played a video, then disconnected the power, the screen would flicker of and on until I reconnected the AC adapter. I am running XP Pro, but I would wager the same problem happens if you are running Vista, which is what was preinstalled on my notebook. I am trying to use as many search terms as possible (such as screen off and on, battery, inspiron 640m, inspirion e1405, ac adapter, screen flicker, video flicker) so that hopefully others will not have as much trouble finding the solution.

No, I didn’t. Is it different than the older one – perhaps a later driver but still different from the latest Dell driver?

I’m having the exact same problem on my Dell Inspiron E1705. It’s been driving me crazy. I’ve been in touch with tech support several times. They tried to tell me I need to upgrade my battery. I got the impression they didn’t know and just blew me off. Told me it was better to watch videos with the battery connected. I’ll be sending them a link to this site. Anyone have a suggestion for the E1705? Could I just download an older version driver over the existing one? Thanks in advance.

I would think you could. I believe that is what I did.

FYI – Dell came out with a fix for this problem yesterday. Just found it this morning. It’s called Intel 945GM Graphics Controller – Maintenence release.
Resolves issue with display flashing after media playback on battery. I downloaded it and so for it’s solved my problem. Can be found on Dell Support under Drivers and Downloads. Hopes this helps.

Same problem here, with E1405. Seems Dell/Intel reacted and release the mentioned maintenance update.
Downloading it right now… hope it fixes the problem.
