Where can change the option to running the device in 54w and 65w mode. Cannot find it in the bios. The funny thing is that my systems stays on in the bios. But when I restart the pc it turns off again after the bee link logo

I have tried multiple 100W USB-C cables and multiple chargers.  Same result: unit will not stay on. Unit is in 54W mode, unchanged from OEM status.

I could live with only using an OEM charger if a replacement were available, since the SER7 7840HS has features, like USB4 and  two M.2 NVME slots, that competitors don't have. However, replacement PSs are not available.

Beelink has the best forum in the mini-PC space (while many other manufacturers has none).  I'll wait for Black Friday and buy another 7840HS.

I use both 100W and 140W on my 140W UGREEN USB-C charger and works good.
I bought this charger from US Amazon (B0B129DM9T)

If you would like to buy an OEM PS as a backup, email
support-pc@bee-link.com
and specify the type of AC mains plug you need. The current price is USD 28.
