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,
had T490 with faulty bios chip. Bought chip out of ebay and soldered on. Laptop starts and works however serial numbers of laptop and motherboard do not match.
I have updated laptop model number.
1) I did not find the way to update laptop serial number - I have this one.
2) I dont know where to get my motherboard serial number and how to update it. Is it somewhere physically on the mainboard? How do I update it?
Hope to find someone to help me with this as I am hitting dead end at the moment.
Many thanks

Hello Everyone,
Needing to identify this chip which is near the USB ports on an HP motherboard. The marking on the chip is ahv31f.
It is completed shorted so I need to find a replacement. Thank you for your help!... -
This chip is shorted thru. Based on what I see, it's either a 3.3V or 5V buck converter, just my guess. The markings on the chip state "S2=AB".
A photo of the chip is attached.
Thank you.... -
Hi,
Not sure whether anyone can help but I'm trying to identify the IC chip in the photo below.
I purchased a faulty Bush DAB radio (model # BD-1801) and identified that an IC chip was blown on it. Unfortunately, I couldn't read the manufacturer name / model number of the IC chip.
I purchased another (working) BD-1801 so that I could open it up to find out the IC details - but the IC chip details are missing (as you can see in the photo.)
Given the two huge blobs of solder either side of it I'm guessing it regulates power(?)
Anyone...
