Re: does it support dual-band? Yes it does. It supports both 2.4ghz and 5ghz Wireless N. It also supports upto the 600mb/s variable of Wireless N.
As far as battery life, I have the middle tier of the computer (without the bigger battery and SSD) and I've been getting about 3 hours. However, if you read my conversations about battery life here (I think they were at around page 193 onward), someone else mentioned that when they use BatteryBar to measure power consumption, they see around 8-12mW/h, but my computer has been consuming around 20mW/h which is very high.
The other poster said he's getting 7-8 hours out of his.

Is it possible that the timer is not starting?
note: powercfg -energy and powercfg -requests show up nothing.
I believe it has never slept properly since I had it but it's hard to confirm as I didn't formally test sleep at the start -

Battery life is ok for some, disappointing for others, and discussed at length in this thread. I understand it's a long thread, but if you google "XPS 15 Haswell Battery Life", you should be taken to various pages in this thread that discuss it. You didn't think we got to 201 pages without any discussion of battery life, did you?adlerhn likes this. -
One thing that will take a LONG time for me to get used to is the fact that home, end, page up and page down are function keys under the direction arrow keys - this is very annoying, especially considering they've got lots of realestate to put these in as seperate keys, but they didn't.
Although, at the end of the day, I'm happy with my purchase, and knew about these keyboard issues before I got the machine - so don't let these small issues put you off an otherwise wonderful machine. -
I got my top tier XPS yesterday, ordered from costco. Immediately I noticed the cpu whine
. It does not happen all the time, usually when the cpu/gpu have some load. But it is continuous when I am in the BIOS.
Did anyone tried the "battery charging configuration", since the whine is only there when the battery is 100% charged, I tried to set the battery charge configuration to "Custom" and have it stop charging at 80%. But it seems this setting is ignored. The battery is always charged to 100%, I also tried other options like "Adaptive" or "Mainly A/C", did not make any difference. Is this a known issue or I just got a faulty one? -

My battery life went from 7-8:30hrs to about 4-5hours after I disabled Bluetooth, NFC and Nvidia devices. My batterylife stayed this way until I reenabled everything that came stock and now my battery life is back to what I expect and I am not using about 10-17W/hr, usually toward the lower end when just surfing.adlerhn likes this. -

my PC sleeps and wakes fine, Is there any benefit to removing/disabling Rapid Start? -
I must be missing something, because nomatter what I've tried, I'm unable to get the machine to boot off the USB drive I just created (to do a fresh install of 8.1). I followed these instructions to create the USB, and near as I can tell, it should be working fine, but no matter what I do to try and boot from the drive (pressing f12 during start up and choosing both options, going into pc settings and choosing to boot from drive in there, etc..), I always end up back in my regular copy of Windows.
What am I doing wrong?
UPDATE: Nevermind - I found the settings to boot using legacy mode with safe boot disabled, and the USB booted instantly -
-
-
-
I ended up returning it. But I really like the machine so I might try again in a couple months when hopefully Dell have fixed these issues. -
While I'm here, before I pass beyond the point of no return, can I ask, which (if any) of the partitions should I keep and/or delete? This is obviously kind of a big deal, because once this happens, I'll be able to reset to factory settings (which, of course, is the point - I just wanna get it right first time).
I'm tempted to clear them all, then let windows deal with that side of things itself, but I'm not sure if I need to create a partition for things like rapid start, etc..
Thank you. -

Just remember when you create the Rapid Start partition, 1GB = 1024MB, not 1000. -

If you prevent the touchscreen from going to sleep:
- does that mean the screen won't turn off when in sleep mode ?
- does the screen draw excess power when in sleep mode ? -
swordofsilence Notebook Consultant
I know - it shouldn't have happened that way, but it did. I had the timer set to an hour before I uninstalled it and I noticed that it hibernated after an hour (after uninstalling) and bypassed BitLocker (mine asks for a password, so it's hard to miss) when I resumed. Really wierd. It didn't happen anymore once I disabled it in the BIOS, which is why I thought I would mention it. -
-
-
But try it without making changes first; I haven't changed that setting yet and I haven't yet had my touchscreen go unresponsive.
And incidentally, when you press F12 to show boot options with your Rufus-prepared flash drive, does the USB drive show up as a boot option and then you get a black screen if you select it (or an error message?), or does the flash drive not even appear as a boot device? -
tricky76, I doubt your XPS 15's hardware is preventing it from recognizing your Galaxy S4. As I recall, you've had it fail to recognize it properly over NFC and USB, correct? What are the odds that both of those systems have failed in your computer? Additionally, you can quickly plug in a different USB device to check that the ports work. If they do, that suggests the hardware is fine and we're really looking at a software or configuration issue. Much harder to diagnose, but swapping out your computer is unlikely to solve it and you could end up getting a machine that has some of the other QC issues that have been documented here (like contaminants under the Gorilla Glass, motherboards with unusually pronounced coil whine, uneven battery endurance, etc.). If you are otherwise okay with your machine, hold on to it and keep trying to find configuration or software solutions.
I have a G4 and I have ordered an XPS 15. I will attempt to synch the two upon receiving the laptop and will report back regarding the experience.tricky76 likes this. -
Hey guys!
I'm surprised about some benchmark of cnet review of the dell xps 15.
They illustrated that dell xps 15 with gt750 is more capable than razer blame with gtx 765m in Full hd res???? Is it true?
Can we play easily with dell xps 15 in full hd without lots of blur??
I'm focus on gigabyte P35K but if dell is capable too with better workmanship...

Maybe that review has wrong data or razor blade 14 has throttling heavier than XPS 15 (but reading review of notebookcheck about Razor Blade 14 there is no throttling on it, while XPS has it).
On paper there is no way that XPS 15 outperforms blade 14.
The review of Razor Blade 14 says that on 3Dmark 11 it hits 3900 points vs 3000 of XPS 15:

Do you have any other ideas?
I'm returning this one in favor of the bigger battery anyway, but it'd be nice to figure out where the issue is. -
Most SSDs (including the Samsung in my XPS 15) don't have write lifetimes published in their specs but according to this article at Tech Report manufacturers estimates for SSD lifetimes "usually range from 20-40GB per day for the length of the three- or five-year warranty." If you set Rapid Start to save to disk immediately, you're going to be over that rate with just two or three suspends per day and that's not counting your actual use when you're using your computer! So to me, it doesn't make sense to configure Rapid Start to save to disk quickly / frequently. It's possible that most modern SSDs will last considerably longer than they're warranted but why take the chance with your data (and your money) if you don't have to?
-
As for SSD wear rate, your example assumes that all 16GB of RAM will be filled every time you hibernate, which I don't think is realistic at all. But you're right, there's a penalty for using this feature. Then again, regular hibernation carries the exact same penalty, so unless you only ever want to sleep or shut down, you're going to pay the price for the convenience. You just have to decide whether you want longer battery life or longer storage lifespan.
On the other hand, that report you linked has some updates at the end that the drives are still running after 300 TB, which at 40GB per day is 20 years, a whole lot longer than the 3-5 year warranty period line you picked from the first page of the article. Given those ACTUAL numbers as opposed to manufacturer estimates and the fact that I've never kept an internal hard drive longer than 4 years anyway, I'd be inclined not to worry about wear due to Rapid Start. -
I've had the laptop for roughly a month today and I want to say some things.
This is the nicest laptop I've ever seen or used. Every time I pick it up there is a little burst of dopamine just by marvelling at the design. The keyboard and trackpad beg me to use them, they are so enjoyable to use.
There are some preferences that will make your experience better: I changed my scaling to 166% instead of 200%, which would be 1920x1080 instead of 1600x900. I use an app called Dexpot to have a second desktop that actually has the resolution set to 1920x1080 instead of just scaled. This is where I use things like Remote Desktop, Photoshop etc. with "disable high-dpi settings".
Chrome's hidden high-dpi setting works great, though some menus do indeed show up out of place, its not the least bit uncomfortable.
Battery life... of course, about half of what was advertised, not as great as expected, but still absolutely superb. I generally use it on-and-off for about 4 hours of the day and only have to charge it once. I think my battery life would be closer to 5 or 6 hours if I watched no video at all, and less than two hours if I was gaming.
For the down side... I am likely to have my laptop repaired soon... I have had a blue-screen on it almost every single day... often several times a day. Every time I open the lid from sleep or hibernate... theres about a 20% chance it will just work fine, but most of the time, my trackpad and touchscreen click will not work. I will fiddle around trying to fix it and it will bluescreen. Otherwise, it will lock up at the login screen, and then bluescreen shortly after (a multitude of different errors). I am also aware of a slight "whine" coming from the top left of the notebook.
If this thing didn't restart in like 15 seconds, this would be absolutely horrific for a laptop... but I'm just so damn happy with it, that I can even live with it when it crashes on almost every single resume.. -
-
Also there is no option in the shutdown menu to hibernate - is that normal?
Should I put back intel rapid start so at least I can save power on manual sleep? -
How easy would it be for me to nuke the system and reinstall - would you just shink the partition and reinstall in a new partition? Will I need any CD Keys to install or will it just go? I am keen to try ... but without nuking it ... let's say Alcatraz-ing it
[I am competent in understanding XP Vista 7 bootloaders - I've clean installed these things 100s of times but the last time I did it was 3 years ago and got 3 amazingly stable 7 OSes]
if I wiped the Dell OS partition will the recovery still work? I'd like to keep the recovery partition -

The second question: I think that is the default. You can add hibernation to the CTRL-ALT-DEL screen in the power options. I remember having to turn this on. It's close to the same place where you can disable/enable fast boot (not Rapid Start).
I personally don't think Rapid Start is worth the lost storage space. Just my opinion though.
For reinstalling, if you can wait, you can ask dell to send you media:
https://www.dell.com/support/diagno...id=4803075&DoNotRedirect=y&redirect=1
If not, I think there is a utility in windows to make recovery disks that you could use to make reinstall discs. In the past, this has wanted to use multiple disks, when the OS should fit on one disk just fine (it did the last time they shipped me recovery media).
There might be a place online where you could find a windows 8 ISO and then you could later upgrade to 8.1, but I'm not sure. It would be nice if what Dell provides is 8.1 and not 8.0. I really don't know though.
I hope this helps somewhat. You are more patient with it than I would be I think. -
As for the blue screens, try wiping and reinstalling Windows if you're comfortable with it. BSoDs are more commonly software-caused than hardware, and it might save you the service appointment and all the risk that seems to entail these days with incompetent techs. In the middle of a pretty nasty experience with that on another laptop right now....
Wouldn't have guessed that uninstalling would have changed ALL of your power settings, but that's not terribly surprising.
Rapid Start has a driver component, so it's not outside the realm of possibility that at the very least empty pages won't get copied to the SSD. It's an easy test though. Try sleeping when nothing is running and time the hibernate phase, then try again when you've got a few VMs or whatever running and eating most of your available RAM, then test again. But when my system is just running with no foreground apps open I'm seeing about 2GB in use, so Windows doesn't try to eat 100% of your RAM all the time.
As for the SSD life, it's not "risking" your data. It's accepting a reduction in storage longevity for a battery life benefit, like overclocking can add performance but with a possible longevity penalty. It just depends on your priorities, but with that test showing that SSDs are going strong after 300 TB, I think the benefits outweigh the costs/risks here. -
N123 -
During the transition to the Sleep state, the software service flushes the standby and modified memory pages to reduce the amount of memory reported as in-use. This can considerably reduce the amount of data that needs to be transferred to the SSD, resulting in improved resume time.
Another function provided by the service is optimizing the amount of active pages that need to be written to the SSD. The service will flush the non-critical active pages during the Sleep transition. Again, this improves resume performance but also reduces the required SSD partition size. -
-
but I didn't expect this ...
my plan of attack -
partition the ssd and clean install on the new partition. when I'm happy i'll use something like acronis or easeus and delete the other partitions and fill up the ssd -
Is the 1080p version of the machine an IPS panel or IGZO like the QHD models?
-

Hi everyone,
I'm just about to pull the trigger and buy the highest spec xps 15. There are stilll a couple of things that I would like to know before purchasing it. I've looked through this thread, but at 200+ pages I've probably missed something so my apologies if this was already answered. So here goes!
- Is the IGZO screen an IPS screen? I would like my new laptop to not suffer from the same viewing angle problems that my current laptop has (TN panel). In other words, do the colors change when you look at it off-center? How about the brightness of the screen?
- How bad are the reflections on the screen? I've never had a reflective display (all my LCDs are matt), and am worried that the reflections will be very annoying, especially in bright light.
- Anyone running linux on this thing? Has the experience been good?
Last but not least: I would like to order from costco since the price is $200 cheaper (I'm in Canada). On the costco.ca site, it says that the wait is something like 3 weeks to process the order. Is this accurate? I would like to receive the laptop before the holiday break. Thanks! -
As far as Costco, I'm in the same boat as you (ordered top spec yesterday), but I noticed somewhere in one of these threads, someone mentioned that they got theirs in like 3 days after it shipped, so it might just be possible to get it before the holidays. But personally, I'm on counting on it (I'm expecting to get it somewhere around new years, probably right after).
Did you get charged tax on your Costco order? Mine had no taxes charged onto it which I found weird. -
There is a thread of configuring Linux on the m3800, which is almost the same machine:
Ubuntu on the Precision M3800 - Dell TechCenter - TechCenter - Dell Community
Follow-up: Ubuntu on the Precision M3800 - Dell TechCenter - TechCenter - Dell Community
Apparently it should run pretty well, with a couple of minor issues. I'll get to try it in a couple of weeks...TheDonkey likes this. -
The reflections aren't bad. I mentioned this twice in the last few pages I believe, but the only time reflections became an issue was when I was at the airport on a sunny day and I had my back to the enormous bay windows looking out to the runways -- and even then it was more of an irritation than a showstopper. In general use you'll see reflections if you force yourself to see them, but they're in a different focal plane than the actual display content, so when you're focusing on content your brain will naturally tune out the reflections.
My laptop was in production for a week and a half, but people who ordered the M3800 recently are now seeing delays of a month or more. I think it's a combination of Black Friday sales and the expected Christmas rush, so I would by no means consider it certain that you'd get it before the holidays. You might, but don't count on it. Sorry!
