Inside Dell Inspiron 17 7779 – disassembly, internal photos and upgrade options

The Dell Inspiron 17 7779 imitates an unibody construction and thus doesn’t have a dedicated service hatch but that doesn’t mean it’s hard to upgrade or replace some of the parts.

1. Removing the bottom plate

Only some unscrewing needs to be done before accessing the hardware inside and then gently lift up the bottom plate.

2. Storage

The laptop holds a standard 2.5-inch 1TB HDD manufactured by Seagate and also offers an additional M.2 SATA or PCIe NVMe slot holding 2280 sticks. Our unit came with only a single 2.5-inch drive without the SSD.

3. Memory, battery and Wi-Fi card

As expected, the machine can be upgraded with up to 32GB of DDR4-2400 RAM but the unit we reviewed had only one 8GB DDR4-2400 chip installed manufactured by SK Hynix while leaving the other slot free for upgrade.

The battery is fairly big and it’s rated at 56Wh. It’s placed under the palm rest area.

The Wi-Fi module is located near the cooling fan and it’s Intel 3165NGW.

4. Cooling system

During our tests, the cooling system proved to be ineffective and it’s not hard to see why. The thin heat pipes leading to the single cooling fan that isn’t placed near enough the heat dispersing grill just isn’t enough to cool down even the not so demanding CPU and GPU.

Hola, a todos; Compre esta notebook en noviembre de 2016 y los consulto para saber si es posible el cambio del disco duro (Hard Disc) por uno de estado solido (SSD). Ademas si es posible alguna mejora sustancial ademas de agregarle memoria RAM.

Dell states that the RAM on this unit cannot be upgraded to more than 16gb and a M2 SSD cannot be added. Both of these statements are patently false. Max RAM is 32gb. Mine came with one 16gb stick and an empty slot. I added another 16gb stick and no problems. It also has a PCIe slot for an M2 drive.

Dell lies about their own products to get you to buy a more expensive computer.
