Hi All,
Anyone know what ic(U1) is that? Phisical p/n :9hHDMH
Or any equivalent ic that i can use?

Re: Solar led chipset
It does not seem to be a good part number
Is there anything else on this ic chip -

Hi SAM,
Only that model no. can be found on physicalComment

Re: Solar led chipset
That number does not look right, it may be custom IC. Did you try cleaning the top of the IC to see if you can see anything else on top of the IC? Any way, what is the board not doing?Never stop learning

The "LED light cannot power on due to this IC faulty and i can't find any part number on top of the IC.Comment

Re: Solar led chipset
I see an IR receiver module, so the IC must be a microcontroller with custom firmware.Comment

Hi, i have an ASUS PRIME Z590M-PLUS board, which had an shorted Z590 chipset. I have succesfully exchanged the chipset to a factory new one, however there is a serious problem with the Intel Management Engine (later on: ME) not beeing activated after the chipset device replacement.
For lower chipset families (on ASUS boards) it worked to program the oldest bios version into the SPI rom, and the bios had activated the Management Engine itself by default - there was a message on the screen prior booting - "BIOS is updating Management Engine ..... . Do not shut down to prevent... -
Hi,
I have a serious problem to program the Z590 chipset SRAM with a Management Engine after replacing the chipset.
The new chipset is factory new and is not containing any Management Engine. Any attempts to program it into the chipset under Windows ends with a failure (eg. Error 20: Management Engine Device not present, or something similar).
Due to the lack of the ME several ports on the board, including all M.2 ports aren't working, booting OS works only on USB. So it's now other way, as to program the chipset with a ME.
Usually on ASUS boards it worked... -

Hi,
I have the above mentioned bord after repair, which was related to a lot of missing smd devices on the back of the board.
There were almost 20 devices missing, caps, resistors and some diodes/mosfets.
The board is generally working now, all PCIe ports are working, Windows installs normally.
However I have a problem with SATA ports 4-7 (the board has 8 SATA ports) - disks are not beeing recognized by the BIOS neither by Windows (which is usually normal in case BIOS does not recognize them).
The SATA 4-7 driver network is quite simple chipset<->buffers/drivers<->SATA... -
So I got this dell motherboard. its a dz87m01 came out of a xps 8700 desktop i believe. it wont post I did some checking on it and was pretty sure the chipset was bad I have a bga rework station so I removed it and it looks like i was right. so i know this thing is old and pointless to put money in but a new chipset is around 25$ and i like fixing things that don't work .
so question is to the people smarter than me is there a possible upgraded chipset that would be compatible as a replacement. The current one is the sr176
