svl7 Posted October 11, 2013 Share Posted October 11, 2013 Dell put a new BIOS for the R4 on their site, you can grab it here: Driver Details | Dell US Changelog: Fixed-add Win8.1 OS type-support Fn+F1/F2/Pause function. Not much, but at least one fix that could come in handy Quote Link to comment Share on other sites More sharing options...
evil_gusgus Posted October 11, 2013 Share Posted October 11, 2013 I'm new here (as you can see) but do any of the m17x r4 BIOS updates fix the lame "plugged in, not charging" problem? Quote Link to comment Share on other sites More sharing options...
thop1544 Posted October 13, 2013 Share Posted October 13, 2013 As far as I know, the not charging problem results from irregularitieswith a parasitically powered microchip in the AC adapter. I've hadtrouble with it too, but the best solution I've 'found' to work isplugging in the adapter, waiting for the blue ring to appear, thenunplugging and plugging back in the cord to the wall, fast enough tokeep the blue light on. Then connect it to the laptop, and it seemsto work.Dellwent to pretty exorbitant lengths to ensure that only an exact (Dell) adapter can be used for each laptop.
