![]() ![]() There are rather more mentions online of 07KGN, which proves nothing. ![]() What’s the difference between 40KRG and 07KGN? I don’t know. One page gives part numbers as: Intel LVDS: X8DN1, Radeon LVDS: 40KRG or 07KGN, Intel eDP: 85M2V, Radeon eDP N23JF. I make it clear by wording I didn’t try hard to verify this yet. I know there’s a VAL90 LA-9931P, apparently LVDS and integrated graphics, and a VAL91 LA-9932P with LVDS and Radeon. My motherboard died :( Mine is VAL90 LA-9933P, which I believe signifies eDP and integrated graphics. Bad: The keyboard sucks, which I already knew, and the three mouse buttons right below the space bar are very crappy (I seem to press them with the side of my thumb in spots that don’t register reliably enough). Good: It seems sturdy, is from the last of the days of being able to upgrade and replace components reasonably, and the display is far better than what I’ve had before. They probably made the same minimal promises in order to be able to use whatever panels they could get their hands on. If Dell bothered to tell anyone the specifications on these, I haven’t heard about it. Lots of people are disappointed when they have the LVDS and can’t upgrade to 1920×1080. ![]() Technical Guidebook shows them to have the same unimpressive minimum specs, differing only in brightness and max power (3.8W vs 6.3W).ĮDP is a displayport thing. Early builds had this and had 1366×768 or 1600×900 panels. LVDS - low-voltage differential signaling. I’ve also seen sales listings that have bluetooth but no wireless, but that seems to be an error (“Standalone Bluetooth 4.0 module is no longer available.”, unlike the E6430 for instance) unless someone put in a bluetooth card on their own later on. If bluetooth is not included, you’re getting Centrino Ultimate-N 6300 or Dell wireless 1506 g/n 1×1, which apparently uses the Atheros AR5B125 chipset (that’s news to me-I’d thought the Dell-branded wireless was all Broadcom, which any Linux/BSD user knows to hate). No one seems impressed by the 1600×900 display at all in reviews. Someone with i7 says too much fan noise, someone with i5 says they have no problem and maybe it’s the i7. Chassis “tri-metal”, whatever that means. 6-cell, 9-cell, review was not impressed by power consumption/battery life, and that the display was weak for what you were paying new (€1000). Dell states clearly that 4th generation Intel processors only support 1.35V, so no putting in plain old DDR3. I think there were quad options eventually, but maybe those were just upgrades people made. First, specs and such, from reading reviews and documents: ![]()
