Wondering if Dell Inspiron 15 i5547-7450sLV is a good laptop? Well, it’s a signature edition to begin with, so it should come bloatware-free. There’s also a quick Core i5 processor and 8GB RAM so plenty to deal with. But does it offer good value for the price? That’s what we’ll find out below…


A good old 4th generation Intel Core i5-4210U powers the Dell Inspiron 15 i5547-7450sLV. It’s one of the Intel’s ultra low voltage processors, with two cores and clock speed between 1.7GHz and 2.7GHz (turbo use). It gets ~3400 points in CPU Mark tests, not quite as much as regular Core i5 processors but that’s because of the low energy configuration. There’s anyway enough performance for common tasks, but also for more demanding work such as lighter games, programming and some image editing.

The notebook features 8GB memory, not unheard of but rare for this price. The motherboard houses two memory slots, and as far as I know both are occupied by 4GB chips. You should be able to remove them and install more if needed – but if you ask me, 99% of people won’t need more than the current eight gigabytes.

There’s a spacious hard drive installed in this Dell. A terabyte in size, you can put hundreds of movies and videos or tens of thousands of images and music files there without problems. However, in this day of Internet streaming not everybody are after a big size but fast speeds. Indeed, this drive seems to sport only 5400RPM rate, so if it’s speed you want you should replace the HDD for a solid-state drive.

Display and graphics

Dell Inspiron 15 i5547-7450sLV’s display is common for these cheaper laptops. It’s 15.6″ in size with 1366×768 resolution. There are no touch support, but the screen should do its job well for daily use of Windows 8.1. The resolution might bug some, but in my experience less than a Full HD is perfectly fine for most uses. If you’re a devout gamer or graphics editor you might want 1920×1080, but others should be good with 1366×768.

Intel HD Graphics 4400 might be familiar name to you. It’s an integrated graphics engine found in many 2014 Intel processor, including the i5-4210U. The Intel HD series is not known to be too gamer friendly, although if you don’t mind low settings and resolution, many titles should work at least decently. For example, the popular game and benchmark Battlefield 4 should get ~25FPS on low details. Fifa 14 and other lightweight titles will get far more frames per second, also Minecraft belonging to that lot of smooth running games.


There are two USB 3.0 ports in Dell Inspiron 15 i5547-7450sLV which is a small improvement from the usual one. As a backup you’ll also get a USB 2.0. In addition, an HDMI output is available for your HDTV or PC monitor.

There’s an excellent AC WiFi adapter to get you connected to Internet. Bluetooth 4.0 is also supported. If you prefer wire, there’s a basic 10/100Mbps Ethernet RJ-45 port for that.

There’s no DVD drive in this computer, so you must get an external optical drive if it’s discs you want to work with. However, there’s a media card reader for SD and MS cards available.

A 720p webcam is installed in the laptop. It should be tad better than a regular VGA camera.

What else to keep in mind?

Dell Inspiron 15 i5547-7450sLV is quite a compact 15.6 incher. It’s just 0.86 inches thick and weighs 4.9 pounds (a bit less than these laptops usually do). The battery life is also advertised as whopping 6.5 hours, but in truth the 3-cell battery will probably reach just 3 or 4 hours on WiFi browsing.

The keyboard is backlit which is rare for a 500 bucks laptop. A numeric keypad is also there, giving you effortless access to the number keys.

As said earlier, no crapware is installed in this notebook. That might do good for the performance as no unnecessary programs are loaded during the start up.


Dell Inspiron 15 i5547-7450sLV tries to be a trendy notebook thanks to its signature edition nature. But performance is what matters to most, and a Core i5 processor coupled with 8GB RAM should indeed offer enough oomph for most notebook users. Other nice things include AC wireless and backlit keyboard, not often seen in this price category. But the overall cost is not too affordable, and doesn’t offer excellent value unless you get a discount. That said, regardless of the price, if you go for this Dell you’ll probably find it’s a keeper.
