I'm looking for a replacement for an aging 15.6" Dell laptop, and as I had a good experience with it, I tried to remain loyal to Dell. The Dell laptop which fits my requirements the best would be a Dell Inspiron 5548 or 5558, with an i7-5500U CPU and 8 GB RAM, and a 2 or 4 GB dedicated graphic card.

My biggest concern is the low resolution of the display. A 768 vertical resolution is just too low for my tastes.

Basically, I'm looking at the following specifics:

**Must have**

- computational power at about the same level as the Dell Inspiron 55548/5558 presented above (i7-5500, 8 GB Ram)
- dedicated graphics card. The GeForce 920M in the Dell 5558 is more than good enough, I don't need any heavy-duty gaming card, I just had bad experiences with integrated graphics cards and I want to have a dedicated one, even if low-spec.
- price category similar to the Dell 5558. It can be slightly more, but not by orders of magnitude, of course.
- USB 3.0
- Removable battery. I tend to use it as a desktop computer for extended time periods, I don't want to waste my battery life-cycles during this time. Or was it an issue only for older batteries that using them while plugged in the mains significantly reduced their total lifetime?
- 15.6 inch display
- At least a vertical resolution of 800 pixels. (as such displays are no longer produced, I guess it will boil down to a 1920 x 1080 screen)
- I guess there is no modern laptop without HDMI and without any Wifi, so I don't know if I even had to mention them.
- A screen which is not too dark. My old screen was slightly above 230 cd/m², I don't want any screen which is much darker.
- Availability in Europe

**Very important**

- CD/DVD drive. I need that a lot, and I don't want to carry around an external drive all the time.
- integrated Webcam. Doesn't have to be good, it just has to exist.
- VGA. I sometimes need to use older projectors which only have VGA input.

**Nice to have**

- Wifi on/off button.
- A case which doesn't bend or fall apart when carrying it around in a bag.
- Dell, but mostly out of subjective reasons
- IPS screen, but it seems hard to get one for laptops in this price range.
- Preferably an SSHD by default, so I don't have to replace it if it only comes with a simple hard drive.

The biggest issues which kept me from buying a Dell 5548 or 5558 was the 768 vertical resolution of the display, and the lack of an optical drive in case of the 5548, and I also didn't like the lack of VGA. 

The nearest I could find was a `Lenovo Ideapad Z51 70`, but two things put me off: the battery is not removable, and the screen brightness is quite poor at only 200 cd/m².

Another alternative I found performance-wise was an `asus F550jx`, but it is very hard to find any information about them on-line, as the Asus naming conventions don't seem to be very friendly. It also seems to lack a removable battery.
