Dell Inspiron 15 7558 Convertible Review


A fresh take. Dell's Inspiron 15 7558 continues the manufacturer's expansion of the Inspiron line into more premium territory, this time with a 2-in-1 convertible design (similar to Lenovo's smaller Yoga machines). Can it inspire us with its rebalanced...

Sleek casing and overall good build quality, IPS 1080p screen for affordable prices in lower-end configurations, Great keyboard with good feedback in spite of a short stroke, Good touchpad with comfortably large roughened surface, Fast solid-state...

Oversized convertible form factor provides few practical benefits, No dedicated GPU options, Only one RAM slot (no dual-channel configuration possible), Case temperatures can be bothersome under load due to hot spots, Audible electrical noise while...

The Inspiron 15 7558 retreats from the graphics-heavy, RAM-packing philosophy of its predecessors and moves instead in the direction of all-round versatility and novelty. The partially metal casing is still impressive for its class (though not...

Dell Inspiron 17-5758 Notebook Review


No more Aluminum! The predecessor had an aluminum lid, while the new Dell Inspiron 17-5758 is now mainly made of plastic. On the other hand, it features up-to-date Broadwell CPUs and a dedicated graphics card. Is this sufficient to make up for the poor...

simple, elegant design, good WiFi reception, replaceable battery, good maintainability, precise touchpad, matte Full HD display, decent speakers

case twists, few interfaces, no Gigabit LAN, only 12 months warranty, keyboard clatters, dark display, unnatural colors, CPU throttles, gets too hot, loud hard drive

The predecessor was good. The Dell Inspiron 17-5758 is only a small update, and many of our points of critique remained unchanged: There are still only a few interfaces, which are unfavorably placed, but at least they are no longer too close to each...

Review Dell Inspiron 15-7537 Notebook


Long-lasting all-rounder. An economic Core i7 processor and a dedicated Nvidia GPU topped with a lot of storage and wrapped up in an elegant aluminum casing - this is the recipe for a versatile and high-performance multimedia laptop. But is it enough...

Good build quality; 4 USB 3.0 ports; Backlit keyboard; High-quality Full HD screen; Generous storage capacity; High graphics power; Low temperature development; Very long battery runtime

Glare-type screen; Low Wi-Fi range; Only 12 month warranty; No mSATA/M.2 slot; Steep price

Comparable contenders would be: Samsung ATIV Book 8, Acer Aspire V7-582PG, Asus N550JV, VivoBook S551LB, and Toshiba Satellite P50.

Dell Inspiron 15 (I15RV-6190 BLK)


The Dell Inspiron 15 (I15RV-6190 BLK) is a relatively thin 15-inch laptop offering Intel Pentium processing power and good battery life for under $400.

Very affordable. Good battery life. Slim profile

No touch screen. Low-res screen. USB 3.0 ports are black

Budget laptops are all about sacrifice, but that doesn't mean you have to settle for a big, clunky system with a bland design and limited features. With the Dell Inspiron 15 (I15RV-6190 BLK) you get relatively good performance in a thin, textured...

Dell Inspiron 15 (1564) Laptop Computer


Power to spare for most tasks ; Great big widescreen to work on

Missing video connections ; Offset keyboard with a too-small number pad

There's no denying that the 1564 has a lot of power--but with so few ports on this laptop, how are you going to make use of it?

Dell Inspiron 15 Review


The Dell Inspiron 15 has average build quality compared to other value-oriented models we have reviewed. The plastics used held up well in our tests, but did show signs of flexing and creaking in spots. The screen lid and palmrest were the two main...

Good looks ; Easy to upgrade all components ; Good cooling system ; Great touchpad buttons

Screen lid doesn't stay closed with the notebook held vertically ; Battery life could be better

All of the 3DMark06 scores for all of the systems listed above were run at 1280 x 800 (for screens with a 16:10 ratio) or 1280 x 768 resolution (for screens with 16:9)

Dell Inspiron 15


Dell's all-purpose notebook offers a bright display, good ergonomics, and helpful software, but multitaskers will want to upgrade the processor.

As you might expect with a budget notebook, the $499 Dell Inspiron 15 is a no-frills machine: It lacks multimedia controls or a webcam, and its graphics performance is poky. But for users on a budget with light computing needs and a desire for a screen...

Dell Inspiron 15


The Dell Inspiron 15 doesn't offer any fancy features or tools you wouldn't find on any other basic laptop. The laptop is portable with a lightweight and thin design. Higher-ranked laptops sport more graphics power and a stronger processor, but the...

The TrueLife screen plays well with high-definition movies, making colors look vibrant and clear

The integrated graphics card is weak and only goes as far as watching movies and viewing images. It won't manage graphics-heavy gaming

The Dell Inspiron 15 doesn't provide any special features or powerful components, but this entry-level laptop is a great laptop for basic tasks.

Dell Inspiron 15-5558 review


Few laptops at this price offer the all-round goodness of the new 15-5558

The Inspiron 15-5558 straddles budget and midrange laptop camps, depending on configuration, asserting excellent build quality and decent performance as you’d expect of a £500+ design. The screen is one of the best you’ll find on a laptop around this...

Dell Inspiron 15 review


This outstanding general purpose laptop provides plenty of processor power and battery life for a surprisingly low price

Overall, the new Inspiron 15 looks like it's a great value laptop, but the £399 Best Buy-winning Asus X552CL trumps this current configuration on both processing speed and graphics power. The Dell has much better battery life, though, lasting around...
