You are welcome! I'm glad I could help.
In case you're wondering how I guessed the part, fortunately, it was fairly well-marked. I wish all the parts were labeled at least to the same extent. You can find the International Rectifier's IOR logo in the lower right corner, so the part number most likely starts with IR. Many manufacturers omit these first characters and leave only the meaningful part, which is either S215310 or S21531D (hard to tell 0 from D from the photo). So you might try googling IRS2153 to see if something like that exists. Infineon does indeed offer a component labeled IRS2153(1)D(S), where (1) stands for the faster deadtime version, (D) means the integrated diode between the Vs and Vcc pins, and (S) designates SO8 package variant instead of PDIP8. This IC is commonly used for constructing switching-mode power supplies, which could be well located inside an active speaker. -
Hello, I think it is an IRS21531D self-oscillating half-bridge gate driver IC from International Rectifier, which is now Infineon Technologies.Comment

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
I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
The SPI chip is an Winbond 25Q256JWEQ model (1V8).
The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.
I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6... -

Long story short:
- dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
- gave the computer to his son a couple years later
- son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
- too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
(seems like the story was not that short)
He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...
