    I'm looking at the bestbuy model of this laptop with the high-resolution screen and the AMD graphics. Does anyone know if that model has the larger battery capacity as well?

    Hi I'm considering the inspiron 7548

    2 questions:

    What can I expect from an R7 270? I can't seem to find many reviews on it and wonder about its performance for gaming.

    If I take the upgrade route, will I void my warranty?

    Thanks!

    The R7 270 is kind of meh. It's going to be slightly better than the R7 M265.

    http://www.notebookcheck.net/AMD-Radeon-R7-M265.109394.0.html

    I wouldn't expect to play any high-spec games from the last couple years, and even less demanding games would need to be run on low-medium settings. It's actually a significant step down from the GT 750M in the 7547.

    So I saw the earlier post that confirmed that the Best Buy model has the larger battery.

    Can anyone confirm how the display closes? I had purchased the 13 7000 series and the screen pressed against the wrist rest. Did that design pull into the new 15 7000 series?

    I am wanting to do the upgrade path with my SSD (Crucial M500 480gb). How do I go about putting the recovery on the Crucial SSD? Since there isn't any media, what cloning program is recommended?

    Really? The 7547 got around 9 hours with a smaller battery. Maybe there's a bug with the AMD card not shutting off?

    Remember the 4k screen... For the most of the time I use the laptop with the sun that reflect on the display, so I need to raise the brightness almost to the highest level. Probably the problem is this.

    Still disappointing. Looking at reviews the 1080p model only gets around 5 because of the smaller battery.

    Oh well, guess this laptop is off my list now.

    Hi,

    I ended up buying the 4K model from Best Buy last week however I have a problem with it.

    side topic: I opened it to update a few components - I took pictures etc so I will post about this later.

    For these that have the 4K model, can you please tell me if you have this grinding noise problem explained below ?

    I have noticed a grinding noised around the CPU area. I opened the back panel and listened to every inched of the laptop: it is 100% coming from the CPU or just above it. It is not the fans (CPU or GPU as they were not moving when I listened), it is not the RAM as I have a good ear and really can tell it is not coming from that zone, and it is not the SSD (that I added in there, see below) as that should not make noise and again I have a good ear, it is not coming from there.

    Full disclosure, 1) I changed the RAM for 2x8Gb Kingston HyperX Impact Black. I tried with them and with the original RAM that came with the laptop. Grinding noise still there. Also, 2) I changed the HDD for a new SSD Samsung EVO 850, but again the noise it not coming from the SSD area (far from the CPU area, where the noise seems to come from).

    I called Dell Tech support this morning, we did their diagnostic procedure. At the end the representative told me to send it back for checks and replacement as Diagnostic was fine but noise still there. As I bought the machine from Best Buy less than 14 days ago, I think I would just bring it back to BB to replace or refund.

    In order to double check my trouble, after the call with Dell, I went to TWO Best Buy stores to listen to the CPU area. These 2 demo units also have the grinding noise around the CPU area.

    I am coming from an old VAIO Z 2008 therefore I am used to noise from that old computer, however all my tech savvy friends with recent laptops tell me that their Haswell i7 do not make a sound at all when idle... Therefore, 1st this grinding sound does not sound good / normal, 2nd I get feedback that other recent laptops do not do that.

    I live on a busy NY Manhattan street but I can still hear this annoying grinding noise while fans are idle and not other moving parts as I have an SSD in there...

    Please, what's your take on this as it does not make sense that the CPU would be making a grinding noise while almost idle with say not even 7% load?

    Many thanks for your help
