Re: Asus G74SX (HannStar 1129) - two motherboards to choose from!

Ah well, the repair place offers "no fix, no fee" so although they tried replacing the GPU their next option (to me) was "replace motherboard" so I just asked for the motherboard back instead. They had a go and all it cost me was courier one way.

TBH I'd rather they had repaired it. I could bought yet another replacement motherboard from AliExpress for less than they wanted for a replacement motherboard.

Interesting because I had a bet with a friend about how people would choose and we both thought everyone would prefer to repair the "no video" motherboard.

One benefit of having two motherboards is that I can take voltage readings from the "no video" motherboard to check against the "no power" board.

This would all be so much easier with a schematic though. I can't even find where I could buy one, let alone download one for free....

I have a dump from an E6420 - is that usable?

Some more details:

"no power" motherboard causes PSU light to flicker so I imagine the motherboard is repeatedly shorting, causing the PSU to reset, etc.

"no graphics" motherboard powers up. If I connect my TV via HDMI then when I boot up the TV recognises that HDMI is connected but doesn't show anything. I'm going to test memory and CPU by booting up a unix USB memory stick and watching network traffic.

Hello,

I bought an Asus G74SX off eBay thinking it was an obvious repair but noooooo....

Motherboard was broken so I ordered one from AliExpress. The motherboard powered up but there was corruption all over the video output, regardless of which output I used (HDMI, VGA, etc. - it was all the same). Looked pretty much like either the GPU or GPU memory needed reflowing or replacing. Sent it off to a laptop repair company, they swapped the GPU and now I get no output at all! (Tried to get some money back from AliExpress seller but no luck there).

Ordered...

Hello,

I've been programming for over 30 years since the old 8-bit micro era. Had lots of practice at build/rebuild computers! School project was a multi-user text-based game written in ARM machine code (~1990?) One instruction per line meant I had to print it out in 6pt courier and even then it was a fat wad of paper!

At university I helped relocate the uni radio station to new offices so I picked up some tips from an EE student there. Built small devices like telephone-to-mixing-desk balanced amplifier,...
