That sounds normal if the system is under high load. I believe that model uses Hybrid Power. When under heavy load with CPU-intensive and GPU-intensive tasks such as video editing or gaming, the laptop draws power concurrently from both AC adapter and battery. When the battery charge falls below 10%, Hybrid Power is disabled, and system performance will drop. If the battery is removed to run on AC alone, or when running on only battery, then in those situations the performance would be reduced.
Hi, Is this normal? Brand new top spec XPS 17 will slowly discharge while connected to the 130w charger. I am seeing 2w to 8w of discharge under load! Thanks.
