Rispondi a: Why is computer getting really warm?Dell Inspirons have terrible placement of their cooling fans, IMO. (I have one too, which I inherited when its fan overheated and broke and was too expensive to repair...I repaired and upgraded, then inherited it...) The fan is at the bottom, blowing air down (?!?). So if it's sitting on top of your lap (i.e. like a laptop...) often the fan is almost completely blocked by its contact with your lap. It's a bad design. I'm quite surprised at how long it has remained that way. The only real solution that I know of is to prevent a snug fit between your lap, or any surface, especially soft one) and the underside of the computer. Prop it up on something so there is airflow to the fan vents onthe bottom. Otherwise, as you've observed, it gets extremely hot. The next step is for the fan's motor to burn out. This is one of the most common failures for the Inspiron; it requires replacement of the fan. It's a cheap part, but repair involves taking almost everything out of the case to get at the fan. (An aside: this repa...
Rispondi a: USB port replacement for SM-T350The chosen answer is not quite correct for the 8.0" 350. In step 8 of the motherboard replacement guide for the 8.0" Galaxy Tab A 350, there is a protective cover plate for the USB port that is removed via two 3 mm screws. There is no flex cable. (It does appear that other Galaxy Tab models do have flex cables, probably hence the confusion. The YouTube video cited is for a different model: also a Galaxy Tab A, but the 9.7" T555 rather than the 8.0" T350, I believe.) HOWEVER: once the protective cover is removed, what is revealed is the back of a standard USB port, with its four soldered anchor points. Once the motherboard is completely removed (see my comments on this procedure--some connectors need to be disconnected first that are not mentioned in the guide), and flipped over, the USB port is seen to have seven pins as well as the four anchors, which must be microsoldered to their pads. Only the middle three of these are really small; the other four are (relatively, for microsoldering) fairly large. But thi...
