Needed a replacement motherboard for a dead i3m, X555L laptop. So while at it, I decided to update to a better processor board.
It was taking a chance, whether everything would work, but the specs indicated everything should be ok.
Apart from being a little heavy handed re-attaching some of the ribbon cables, which resulted in a heart beating moment, reseating them get everything working fine, so I now have 2 X55l Laptops each both able to perform their Astrophotography tasks.
I could have bought cheaper from China, but I wanted the reassurance of a local supplier, in case things went wrong....
