That is your wireless card. Follow the removal procedure in the Service Manual. Be careful when disconnecting and connecting the tiny antenna plugs that fit over the tiny posts on the card (kind of like snap fasteners on a coat). They are fragile. And be careful to note which sides the white and black cables connect to before you disconnect the existing card. Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. It's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard. (Repeatedly touching a metal case part is not sufficient mitigation with modern components.) One possible hiccup: your Windows licence will be tied to the motherboard. It may be possible that Microsoft may enable Windows activation for the new motherboard, if you prove to them that you had to replace the old one. Look up the Microsoft page for Windows 10 or 11 activation issues. There is a form you fill out, and then either you call Microsoft or they call you (I forget what the sequence is), and they are quite helpful.
Hello, I've recently purchased a new motherboard from Dell as the one on my original Aurora R10 only supports 3000 series AMD CPU's and I had already purchased a 5000 series upgrade. I will have to swap out the motherboard and the only component I can think of causing me any trouble is the one shown in the picture attached. It seems to be installed in a manner more permanent than the CPU, GPU, Ram, etc.  I was wondering if anyone knew what exactly the function of this chip is, such that I may know what to expect when leaving it behind? If anyone else can think of any other sticklers with a motherboard swap do reply as well! [IMAGE]
