Re: Searching for Weltrend part



thanks... looks like I found a local source.
Take care...

I am searching for a smps supervisory part by Weltrend - WT751002 or WT751002S in an 8 pin dip package. This is to repair my dead ATX power supply. I see that the Asian market has plenty but I do not trust their authenticity and do not wish to wait the time (2 mo) for shipment to the US.

So, does anyone have a spare that they would be willing to part with for a reasonable price? I believe that the Weltrend WT7502 looks to be a drop in replacement. Maybe there are others that would also cross to my original part, I do not know.

If anyone is willing to help it would...

Re: Need HP Prodesk 600 G6 Desktop Bios dump



Just to say thanks again.
I ended up reading all the posts I could and finally understood what to do.
Initially, I tried reading the 128kb part while soldered to the board but had no luck. I was using the ICSP port on my T48 programmer. Attempted to use the spring clip as well as using 'grabber' clips on each pin. No luck at all.

Therefore, I unsoldered the part and modified the dump using RClocker with the chip installed in a zif socket. So, all is good again, the admin password is cleared....

Re: Need HP Prodesk 600 G6 Desktop Bios dump

OK, I understand. Thank you for the explanation.

I see earlier in this thread where you supplied the bios dump for a HP ProDesk 600 G6 PCI Microtower PC (9CV80AV). This is my also my model of computer. Will this dump also work for my machine or do I need to supply you with a copy of my locked bios? I thought that maybe each bios dump may have machine serial number information embedded as an additional security measure.

I certainly appreciate your help. I will attempt to read my bios flash part today.

Hi hoaca388 -
Not sure I understand. What do you mean 256Kb or 128Kb is fine? Are you saying that if you reflash either device that will suffice to clear the admin password?

Also, do you know if it is possible to read and flash the parts while still soldered to the motherboard?
thanks for the response....

Re: Need HP Prodesk 600 G6 Desktop Bios dump

I am very interested in clearing the forgotten admin password on my 600 G6 mini tower desktop but I am confused as there appear to be two SPI flash parts on the motherboard. One is a 16pin 256Kbit part and an 8pin 128Kbit part. Would someone inform me which of the two (or both) need to be reprogrammed?

Also, I already own a programmer which will allow me to read/write the required flash part. I would prefer NOT removing the part from the motherboard. So, I am curious whether there has been success in flashing the part while...
