It performs good as expected for first 5-10 min then gpu clocks down to 200-300 mhz (temp never exceed 60C)and stays at that clock even after temp less than 55C. This happens for every gpu workload. i have the lastes bios and drivers provided by lenovo.We need bios with higher temp targets (73-75C) and throttle bug fixed.Currently it is performing less than 50% of other ryzen 2500U laptops. Please look into it asap.

Welcome to the Lenovo Community Forum!
First of all, we're sorry for the trouble. May we know if the problem occurs while the laptop charger is connected or not? May we know the power management settings that you set up to the laptop? Also, when did the problem start? We're looking forward to your reply.

Also the cpu package power stay low at 6.5-7 w at full load which not even 50 percent of cpu tdp(15w).quick fixes and some customizable options for tdp and and target temp are urgently required.
*edit* hwinfo reporting wrong stat for power, the apu is on full 15w load.

i checked apu power again by amd uprof and the throttling is because the apu is consuming 15w even at 50 % load. gpu is not being prioritize for power.A 25w tdp option is required.
