Re: Laptop repair chip level books and videos
I do partially agree. However, i meant for beginners who have little or no electronic background. As most of the professionals do NOT explain the basic grounds. Sorin, i believe, explain things on that level. However, he have many draw backs but i thought it will be a starter point.Comment

Hello, first of all, excuse me, I am using the translator, English is not my native language.
I have a Lenovo ideapad 330S - 14IKB laptop.
The tablet did not recognize me when I connected it, so I checked the device manager and I realized that there were many with the exclamation mark, so one by one I began to update their drivers until the sign disappeared of admiration, I even updated the BIOS, and the laptop rebooted normally and worked, so far so good, but the tablet still did not recognize me, I read on the internet that it could be due to a... -
Asus Vivobook 15 (board X513ea R2.0) gone dead when user plugged an iPhone cable into the USB-C port during boot. Now there's no LED light, no power at all. I checked all MOSFETs and capacitors, no shorts found. The board only has 3.3V and 5V present, no other voltages.
I injected 3.3V into the EC chip power rail (ITE IT5125VG 128), and it draws 80mA, while the 3.3V LDO chip RT8249C has a max output of 100mA. I checked the boardview and found there are only two chips on this 3.3V rail, EC and Realtek audio chip. So I think EC could be the problem.
I found the EC chip...09-14-2024, 02:09 AM -
This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
Hi. In the process of troubleshooting an MSI GE78HX laptop that does turn on (on its own), turns on the backlight on and off in infinite cycle, turns on RGB keyboard backlight and light bar. The CPU gets hot, and its fan spins.
The laptop charges the battery, turns on charging lights, which leads me to think the EC (ITE5571E) is ok. Laptop has no shorts, apparently. Memory is ok, tried it in another machine. Tried 5 different sticks in this machine as well, does the same. Memory connector seems ok, no pins bent.
First, I am going to try to backup and reflash its BIOS,... -
