Does the Razer Blade 16 RTX4090 works with a 100W charger?


Hello, 

I'm currently using a Razer Blade 16 4090, 2023. 

I'm trying to use USB-C at work because I saw some videos explaning that the laptop can run with 100W while doing small tasks. The issue is that when it's plugged in with a USBC + 100w adaptor, the laptop keeps discharging the battery, even doing almost nothing, 

 

How can I use a 100W USBC charger and still working on my laptop without discharging it? Should I do something different in configurations ?  Or it really doesn't work with a 100W charger? 

 

(I have already tried the charger and cable, it works with 100W. So it's not that they don't work).

I understand your concern regarding the battery discharge issue when using a 100W USB-C charger with your Razer Blade 16 laptop. There are a few factors that could be causing this problem. Here are some suggestions to troubleshoot and resolve the issue:

  1. Power settings: web technology app USA Check the power settings on your laptop to ensure that it is not set to a power-saving mode or limited performance mode. Adjust the settings to allow for maximum performance while connected to the charger servies.

  2. BIOS and firmware updates: Make sure that your laptop's BIOS and firmware are up to date. Manufacturers often release updates that can address power management and compatibility issues.

  3. USB-C port capabilities: Confirm that the USB-C port on your laptop supports power delivery of 100W. Some laptops have USB-C ports that may not be capable of providing full power delivery, so it's important to verify the specifications of your specific model.

  4. Charging cable: Ensure that you are using a high-quality USB-C cable that supports power delivery. A faulty or incompatible cable can affect charging efficiency and cause battery discharge.

I have the same issue with a 100W and a 230W charger.

It would be great to have a way to reduce the performance of the Blade 16/18 so the battery does not discharge while having them connected.

 

Also on battery mode it woud be great to have a way the limit power usage of CPU and GPU, so that the battery last as long as possible (of course I am using adavanced opitmus, power-saving mode). Still there could be more done to reduce the power usage. 
Would it make sense to deactivate some of the efficiency cores to extend battery life?
 

Of course all this with regular office use not for gaming. For gaming the power supply is really needed.

The Razer Blade 16 RTX 4090 is a high-performance gaming laptop that requires substantial power to operate optimally. While it is always recommended to use the official charger provided by the manufacturer, it is important to check the power requirements of the laptop and the specifications of the charger to ensure compatibility.

Hello Olivia,

 

but what is the USB-C charging option then for?

If I talk about gaming or other high performance task, I of course need the 330 W adapter.

 

But it should be possilbe to work with a USB-C docking station with low performance tasks like Word or Outlook, without having to be afraid, that the battery is discharging. Especially in Optimus and power saving mode, as the Microsoft Office for sure, does not need the RTX 4090.

 

Best regards

@GregoryBachinski @pdchristian do you have any updates on that topic ? because i thought it´s possible to do “simple stuff” with USB-C charging. now reading that this is actually not possible is not more than bad marketing! ;-((

Hello,
I even have the same issue when I use a 230W Razer charger.

I would expect that the power limits would be reduced as low, that the battery is not draining, if a 100 W or 230 W adapter is connected. 

Or maybe the user could then decide to:

  • Maintain charging level
  • Have maximum performance

Dear Razer team, it would be really great if you could provide a solution for this topic.

Also, I am  using my Razer also for office work with a Dell monitors (65W & 90W charging).

Looking forward to your answer!!!

 

Thanks!

So you are saying even the 230 w charger lets the battery drain ???

I don`t think it will drain if I only work with Office. I have not tested that, yet (only with the 100W).
 

It most definitely drains if I am gaming.

This is why I proposed to be able to set the Power Limits lower for a low power charger.
For me it would be OK to have lower frame rates, if I have a low power adapter attached.
à Of course it would be perfect to have a choice as a user

 

What actually happens if I am gaming with the 230 W adapter on the Blade 18 (4090). For quite  some time I can play with high frame rates. Then when the battery is down to about 20-30 the game starts to lag.

okay. got it. my RB 16 is on the way… maybe i can test the 230w charger next week….  ;)

The Razer Blade 18 is fantastic. From what I saw in the test the Razer Blade 16 is also fantastic.
My previous Laptop was an Alienware X15 R2 3080Ti. There the Razer is soooo much faster and quieter!

So you can really look forwart to your new Razer Blade 16 :-)

I am always using Sonys NC headset (wh-1000xm4). So even the notebook (it doesn´t matter which one) would blow all the time, I wouldn´t hear that ;-)) This headset is one of my best buys ever…. ;-) 

The Razer Blade 16 RTX 4090 likely comes with a power adapter that provides more than 100W of power output to ensure optimal performance during gaming and other demanding tasks. Using a lower wattage charger, such as a 100W charger, may not provide sufficient power to the laptop, potentially leading to slower charging speeds or limited performance, especially during heavy usage.

It's essential to use the manufacturer-recommended power adapter or a charger that meets or exceeds the power requirements specified for the Razer Blade 16 RTX 4090 to ensure safe and efficient operation of the laptop. Using a lower wattage charger may not deliver the necessary power, affecting the laptop's performance and potentially causing damage over time.
