    Re: About network cards failures...

    carefull, most laptops dont use magjacks - they use a seperate transformer.
    post a foto of each side of the board near the connector.

        the transformer says "PULSE" on it and is marked U30 on the board.
        page2 on the schematic.

            Thanks for the warning!! I have two boards here from old acer laptops that have the black rectangular transformer, thats why I thought the Compaq has the transformer on the jack....
            Ok, here are the photos.
            Well it seens to be a diferent laptop, mine is a PIII. It says N600c series pp2040. The squematic you've found looks like a pentiun 4.

            I runaway Of P4's as far as I can .

                is the network controller on a seperate board? i cant see one!
                does the socket have a maker or part number on it?

                    Well, I already noticed that, I thought that the nic may be integrated on the chipset but I don't know. It doesn't have another board apart the power board that I removed for the photos. It is a 13" laptop very small for the age from my point of view. What you see in the photos is what it has, apart from the power board, the wifi card and the ram

                        found this:

                        it says the network interface is optional on a mini-pci card.

                            My god, no you are God, I never imagined that, it has an Intel 2200bg wifi on the pci slot so I thought the Lan nic was damaged I'm going to look if I can find that mini pci lan card somewhere.
                            I never saw a thin like this...

                                        Home network connection problem
                                        by davg
                                        I just bought a new ThinkPad laptop and I need to connect it to my home network. I have several computers on my network and can see each other in File Explorer and the older ones can communicate with each other (even with the new one) but the ThinkPad can see the other computers but can't communicate with them. I get the (network error 0x80070035 The network path not found). I tried several scenarios that I found on line but none of them worked?? Since the other computers on the network can communicate fine I'm assuming the problem is with the setup of the ThinkPad? All computers are running Windows...

                                        Maximum speed should be marked on network ports
                                        by japlytic
                                        I noted that a number of consumer entertainment devices have the maximum speed marked on the wired network port and considering that there are broadband plans faster than 100 Mbit, the wired network port can be a bottleneck since some routers do not have Gigabit (only 100 Mbit) support for the WAN port let alone the wired network ports.

                                        One other thing: Certain low cost network cables only have two pairs which limits speed to 100 Mbit.​

                                        Hello Guys

                                        I have a ASUS Rog strix laptop that I bought recently to fix and the previous owner spilled water on it . He brought it into a repair shop for them to check it out and instead of fixing it they damaged the battery connector of the laptop ! Other than that they damaged damaged nothing . But since the liquid damage the laptop only turns on and the keyboard lights up and then immediately turns off. I really want to repair this laptop and I also have experience in repairing phones etc and laptops and a bit of soldering but the diagnosing part is where I need help with and...

                                        Identification of Component T5 on NEXIQ USB-Link 2 (damaged due to crushing)
                                        by Tomylee
                                        Hi everyone,
                                        I'm currently repairing a NEXIQ USB-Link 2 that was physically damaged due to crushing. After a thorough inspection, it appears that only one component is visibly damaged: the T5 component, located right next to the Mini-USB port.

                                        It's a 4-pin SMD component, with one pin at each corner, aligned front-to-back along the USB port axis. Unfortunately, it is broken, and there are no visible markings left on the part to identify it.

                                        I'm looking for help with the following:

                                        The exact identification or part number of the T5 component
                                        ...

                                        ASUS TUF X570-PLUS doesn't power on: no VRM_EN signal.
                                        by ShadowAi
                                        Hello, I have an issue with the motherboard. Specifically, it doesn't power on, more precisely, the POST initialization doesn't occur.

                                        Let me start from the beginning, the motherboard suddenly stopped working one day. There are no beep signals from the speaker, and the debug LEDs are not lighting up. After inspecting it under a microscope and using thermal imaging, I didn't find anything that could be damaged.

                                        After that, I began voltage measurements, in which I noticed the absence of VDDQ, VDDP, VTT, and VPP lines. Later, I checked if there is an EN state on these lines,...
