Ajuda para Dell OptiPlex 780 Small Form Factor Repair: aprenda a consertar com as próprias mãos.

The OptiPlex 780 is a series of low-cost desktop computers released by Dell in 2009. The line includes four unique designs: a large “Desktop” computer, a slightly thinner “Mini-Tower” style, a “Small Form Factor” (SFF) size, and a tiny “Ultra Small Form Factor” (USFF) design. This page is specifically about the Optiplex 780 in its Small Form Factor size. To identify this computer, look for a sticker on the top, bottom, or back containing Dell’s service tag and service code (as shown in this Dell support article). These are identifying codes which you can enter on the Dell support website to find your exact computer model.

Inside, the OptiPlex 780 SFF has an Intel processor and integrated graphics. It can support up to 16 GB of memory in four slots. Three drive bays (two of which are open to the front panel of the computer) can be used for hard drives, an optical drive, or a floppy drive if you need to interface with older software. For expansion purposes, the motherboard has a PCIe x16 slot on it; you could use this to add a dedicated graphics card to your computer.

Accessing the internals of the computer is very easy: simply pull a latch at the back of the computer and let the side panel slide off. This design makes the computer easy to repair or upgrade. You can see instructions for replacing most of the internal components in the OptiPlex 780 SFF service manual.
