Dell Inspiron 1564: Mobile i3/i5 for the Masses

Dell Inspiron 15 Battery Life
Dell shipped our Inspiron 15 review unit with their standard 6-cell, 48Wh battery and advertise it as being able to hit up to 3 hours and 43 minutes of running time. For our battery life testing, we set the screen's brightness to a measured 100 nits.
The running time of the Inspiron 15 isn't exactly breaking any records, but it's not a showstopper and Dell should be commended for at least a measure of truth in advertising. Leaving the computer idle at about 30% brightness in the software settings resulted in a battery life two minutes longer than what Dell advertises. When we put the computer to basic use, we get a touch over three hours, which is just about the bare minimum of what a modern notebook should be able to provide. When video playback enters the equation, however, battery life takes a swan dive, losing a full hour of running time. The Inspiron 15 is still managing two hours of useful life, though, just long enough to watch a movie before having to put the machine into standby.

I am assuming that since these are the new H55 based chipsets, hopefully the HDMI port will be about to output a 5.1 track? Or possibly also a DTS-HD or TrueHd track that comes off a bluray?It would be a shame if the HDMI ould output stereo. Can anyone confirm or deny?

I wouldn't buy any of these if I were serious about decent gaming. How sad.PyroHoltz - Thursday, March 4, 2010 - link
Where are all the Ultra Mobiles built on the arrandale chips?JarredWalton - Thursday, March 4, 2010 - link
Rumor is that Arrandale ULV has experienced delays and will show up some time in the next ~3 months.cjcoats - Thursday, March 4, 2010 - link
I recently had that experience buying a 2-socket Nehalem workstation from Dell. We're even having to do hardware installation for ourselves ("We'll sell you a SSD but we won't install it"). It was so bad that if it had been up to me instead of the bean-counters, I'd have said "to H--- with this" and purchased from a different vendor (at least two of which were quite willing to deliver exactly the requested configuration).FWIW

I've been following laptop progression for awhile now. I'm picking out a new one in summer for Grad school. Every article I read I still want whatever Asus UL will be out around then. These Dell's just don't stack up and for the $ when Asus offers free accidental coverage for a year as well.therealnickdanger - Thursday, March 4, 2010 - link
I know I've said this before and perhaps others have as well, but it would be nice if AT could add a "classic" gaming suite to its benchmarks. If a 'puter can muster over 60fps in games like FC2, obviously it can run older games just fine, but once you enter this mainstream and lower-end market, gaming performance is suspect.We're looking at this laptop that does 20-89fps, depending on the game. IMO, the biggest reason to use a gaming laptop is for LAN parties and mobile multiplayer: WoW, CS:S, UT3, L4D, Halo. If I'm in the minority and my request is unreasonable, so be it, but I believe there is a large gap in AT's gaming benchmarks when it comes to mid-to-low systems. I don't care how well the Core i3 IGP plays Crysis at 1080p, but its performance in the above games at 720p would interest many people.
We can assume a lot, but concrete numbers are nice to have.

Another laptop that continues the trend of taking a decent platform and pairing it with a dedicated GPU too slow to be useful. Have the major OEMs lost all ability to build a balanced system? For comparison, the Acer Aspire AS5740G-6979 for $799 at Newegg has a slightly lower-clocked CPU, larger HDD, and a Mobility Radeon HD 5650 1GB.strikeback03 - Thursday, March 4, 2010 - link
I hate everyone trying for a "balanced system", it means pretty much everything with a fast CPU has a GPU that I don't need.JarredWalton - Thursday, March 4, 2010 - link
Or there's the http://www.bhphotovideo.com/c/product/671930-REG/A...">ASUS N61J for ~$1050 with 5730 and an i7-720QM... though battery life is going to suck on that, I'd wager. The Inspiron 15 is decent as a lower cost model, but the i5-520M is overpowered for what you get.
