Dell Precision 5680 - RTX 4090 capped at 70W while CPU hits 95°C+ (55W) - Any way to bypass the GPU power limit?

Hey everyone,
I’ve been using a Dell Precision 5680 with an i9-13900H and RTX 4090 Laptop GPU. I know this isn't a dedicated gaming laptop, but I’m seeing some frustrating power distribution during gaming :

• The Issue: My GPU seems to be hard-capped at 70W, even though the hardware should be capable of reaching 95W (TGP).
• CPU Behavior: The CPU is pulling around 55W and hitting temperatures above 95°C-100°C most of the time.
• Thermal Throttling: Because the CPU is running so hot and pulling so much power, I suspect the system is "stealing" power from the GPU or thermal throttling the whole package.
My Questions:

  1. Is there any way to force the GPU to pull its full 95W?
  2. Would a vBIOS flash (maybe from a 7680) work on this model, or is the VRM cooling too weak for that?
  3. Has anyone tried using PTM7950 on this specific chassis? Did it help stabilize the CPU enough to let the GPU boost higher?
    I'm already using the "Ultra Performance" mode in Dell Optimizer and the "High Performance" plan in Windows, but the 70W cap won't budge.
    Any advice from fellow Precision owners or modders would be appreciated!

Thinking of flashing 125W VBIOS from Precision 7780 to my Precision 5680 (RTX 4090) – Is it safe?

Hi everyone,
I have a Dell Precision 5680 with an i9-13900H and an RTX 4090 Laptop GPU. Currently, the GPU is hard-locked at 95W TGP, which feels like a waste for a 4090. the temps are surprisingly low, and the laptop seems to have plenty of thermal headroom.
I’m planning to flash the 125W VBIOS from the Precision 7780 (also a 4090) to unlock better performance. To manage the thermals, I intend to disable Turbo Boost on the i9 to give the cooling system more breathing room for the GPU.
My questions:

  1. Since they are both from the Precision lineup, how likely am I to run into ID mismatch or port issues (HDMI/Thunderbolt)?
  2. Is the VRM on the 5680 robust enough to handle the 30W increase (from 95W to 125W)?
  3. Has anyone attempted this specific cross-flash before?
    I'm using NVFlash and I have a full backup of my original VBIOS. Would love to hear your thoughts or any warnings before I pull the trigger.
    Thanks!

Hey everyone,
I need help with my Dell Precision laptop. Everything was fine until yesterday when the battery LED started blinking amber (orange).
The problem:
• The battery is stuck at 83% and not charging.
• The battery icon disappeared from Windows.
• When I run BIOS diagnostics (F12), it says "Battery not installed" or "Communication Error."
• If I unplug the charger, the laptop becomes very slow and laggy.
• Sometimes it won't even turn on unless the charger is plugged in.
This happened suddenly. I've already checked the charger and it seems fine (recognized in BIOS).
What could be the reason for this? Is my battery dead? And is there any way to fix this or should I just return it since I still have a few days of warranty left?
Thanks in advance!

I bought a laptop recently and the warranty had already expired. I contacted ASUS via email about 15 hours ago to update it. Does anyone know how long they usually take to respond and change it? I’m trying to sell the laptop as soon as possible.
