I had a Switch 2 cross my path and I found a short related to one of the multi-phase buck converters for SoC power. It's one of a pair that says "dialog" on it. On switchbrew.org it's identified as DA9092-AIOV2. The problem is I can't find this chip anywhere for purchase. Donor boards are hard enough to come by and too expensive to take the risk. There's other similar chips available for bulk purchase at the Renesas manufacturer website but they have different variants that I'm not confident in: DA9092-AKOV2, DA9092-AKOVC, DA9092-APOV2, DA9092-APOVC. Does anyone have a source?

Thank you, sir!...

This helped! Thank you

Please upload again! The website just says "Invalid File Specified". I would like to have these schematics. Thank you!

I tried. Still no display. I'm sure the BIOS file is good but I might have another problem causing this symptom. Thank you for your help....

I have the same laptop. I need the BIOS for the service tag below. Original attached.

I've already said hi. Why is it making me do this again?

I repair consumer electronics in a small business supporting a popular brand. I joined a motherboard repair team that had 5 years experience. Upon 4 months of fixing mostly Playstations and XBox's, the whole team quit due to issues with the owner. I now carry the weight of the team myself and I must learn quickly to make my lonely department worth keeping. I am Left Over.
