Here I want to present the most likely ways to solve the problem with the laptop freezing when starting up on the logo.
0:14 - Consider the first method in which the reason may be related to the battery. To find out if it is the cause of this problem, it must be removed. Unfortunately, at the moment, with a number of laptops this can be difficult, because the battery is inside the case. Having removed it, I launch the laptop, but, as we see, the problem has not been resolved.
0:39 2 Way. Perhaps the reason may be related to RAM, namely due to poor contact, its malfunction, or, in the worst case, due to the failure of one of the slots on the motherboard. In this case, if the laptop has 2 RAM slots, it is worth trying to run it on one, gradually inserting it into a different slot. Also, memory strips can be checked using the MemTest program, or, for example, on a known good laptop.
1:09 3 Way. Next, I decided to remove the Wi-Fi adapter, and, as it turned out, it has one melted contact. Having started the laptop without a Wi-Fi module and battery, unfortunately, it was not possible to solve the problem, and the result remained the same.
1:28 4 Way. Let's move on to the next method in which I remove cd-rom from the laptop. In your case, it is probably completely absent. Then we try to turn on the laptop again, unfortunately, the situation has remained unchanged.
1:43 5 Way. We move on, and in this method, the reason may be due to a malfunction of the hard drive, which in most cases causes the current problem. Because I already extracted it, try to start the laptop without it. As we can see, everything remains the same, let’s try again, and this time it started successfully, displaying a message that it cannot find the operating system. You might think that a solution to the problem was found in this case, but as it turned out, this is not so. On subsequent launches, it hung again. Having disassembled the laptop, you can see that on the lower part of the case there are traces indicating that it was once shed. In this case, it is worth trying to start the laptop without a keyboard and a touchpad, as Perhaps due to a malfunction of these elements, the laptop freezes on the logo when it is turned on. I must say right away that this did not help in my situation.
2:46 6 Way. Therefore, we move on to the next method, where a possible problem is caused by a bridge blade on the motherboard. I have already removed the motherboard and now I will try to warm the north bridge on it first with a hairdryer, along the edges of which I applied flux. I warm up the bridge for about 2 minutes. when it is heated around the entire perimeter and temperature of about 150-200 degrees. After the board, and especially the heated chip, cools down, we will try to run it without unnecessary details. We see that the launch was successful the first time. It remains to assemble the laptop completely and try to restart it. As a result, we can see that everything is working successfully. Thus, the heating of the bridge made it possible to establish that the problem was caused by its dump, and since This solution is only a diagnostic measure, which will allow the laptop to work for a short time, in this case the north bridge will have to be replaced with a new one or the motherboard will be completely replaced.
In addition to the presented methods, the problem can also be caused by the failure of both the BIOS firmware and the microcircuit on which it is wired, as well as a possible, but extremely rare problem, may be the failure of the processor.
In conclusion, I want to wish you a successful solution to the problem.
