Why did my AN515-45-R2NV laptop suddenly turn off and is now showing a solid orange light and not charging while having fps drops while playing games?

I have an Acer Nitro V AN515-45-R2NV

It has a ryzen 7 5800H cpu and a Nvidia 3060 gpu.

The other day I was gaming(playing valorant) for like an hour then my laptop just suddenly turned off and it doesn’t turn on if it’s not plugged in but when it does turn on after like a few minutes it just shuts off. It still recognized the battery but it for some reason it doesn’t use it for power(i.e. it not turning on if it’s not plugged in).

I disconnected the battery and pressed the power button for 1 minute then reconnected the battery and now it turns on even when it’s not plugged in but the problem is I tried gaming again but there’s suddenly major fps drops (180-240 fps drops to 12-21 fps) and packet loss of 30-50% with the charger plugged in then I thought my charger wasn’t working cause my battery wasn’t charging. Then bought a 2 new ones but same problem keeps coming up. Then I tried using it without the charger the fps became stable (remains at a steady 60fps) but since the battery doesn’t charge I now don’t know what to do.

To be clear when I open other games it’s the same not only with valorant.

Hi Craigggg,

Thanks for the detailed post. Your Nitro AN515-45 symptoms—sudden shutdown, solid orange LED, battery not charging, and FPS drops when plugged in—point to EC firmware confusion or power rail instability.

The fact that it only boots when plugged in, then shuts off, suggests EC confusion or a VRM event.
FPS drops when charging (but stable on battery) imply throttling triggered by unstable voltage or misread power states.
Your battery reset helped partially, but the charging issue and plugged-in throttling remain.

What to check next:

Battery age: If this is the original 2020–2021 battery, it’s likely degraded. A 5-year-old Li-ion pack can misreport charge levels or trigger EC faults. Replacement may be necessary.
BIOS version: The latest official release is v1.11 (2023/09/18) https://www.acer.com/us-en/support/product-support/Nitro_AN515-45It includes PI FP6_1.0.0.C and CI security updates. No newer BIOS exists for this model.
AGESA firmware: v1.11 likely includes AGESA ComboV2 PI 1.0.0.C, which is older than AGESA 1.2.0.7 or 1.2.0.A used in newer Ryzen platforms. These later AGESA builds improved EC behavior, battery detection, and power state transitions. Unfortunately, Acer hasn’t released a BIOS with newer AGESA for this model.
BIOS install: If you're not already on v1.11, install it using Acer’s official Windows-based tool.
Power monitoring: Use HWiNFO64 to log VRM temps, battery status, and power draw during FPS drops. Look for signs of throttling or voltage instability.

Forum context:

Similar cases have surfaced with AN515-45 units showing EC confusion post-shutdown. If BIOS v1.11 and a new battery don’t resolve it, it may be worth escalating to Acer support for EC revalidation or board-level diagnostics.

The flashing green/orange LED usually indicates a charging problem. This could be the power adapter, motherboard, or battery. Shut down the laptop, take the battery out, and try to start the laptop up with only the power adapter. If it doesn't start, you may have an adapter problem.

Click Device Manager
Expand Batteries
Right-click Microsoft ACPI-Compliant System.
Choose Update Driver Software.
Make sure you are connected to the Internet, the check for updates.

Other things you can try....

Run Windows 10 Battery Diagnostics

If your battery isn’t fully charging, the first thing you can try is the Battery troubleshooter in Windows 10.

Open Start > Settings > Update & security > Troubleshoot
Scroll down then click Power
Click Run the troubleshooter

Complete the wizard then restart your device to see if the problem is resolved.

Most laptop computers include their own factory diagnostics utilities, too. It is recommended you also use those to test your battery. Accessing the diagnostics will vary by manufacturer, so, consult the documentation that came with your computer. Before you run a test, you might need to first fully charge the device to 99 or 100 percent, disconnect the AC adapter, boot into the diagnostic utility then run the test.

Check if Your AC Power Supply is Properly Connected

Sometimes the power cable connected to your AC power supply brick might be loose. Check to make sure it is fitted and secured properly.

Try a Different Wall Outlet and Check for Low Voltage and Electrical Issues

The other day, my house had some serious electrical issues going on. You would be amazed how much voltage issues can affect the performance of your system. Plugging in my laptop into an outlet within my room dimmed the light, while an outlet in the living room caused it to wink.

Another room it remained constant but charging was horribly slow. This, of course, meant I had low voltage issues and with so many appliances competing for the little bit of faulty energy, it made it even worse. Ultimately, I ended hiring an electrician to sort out the issues. After fixing it up, my laptop started charging normally.

Test with Another Charger

I mentioned the AC power adapter earlier. It’s possible your charger might be the culprit. If you have a working spare laying around the home, give it a try to see if it charges. You can also borrow one from your work colleague if you don’t have any. If you don’t have access to another charger, try yours on another laptop to see if it charges the device.

If you are mixing and matching laptop power adapters, make sure you choose the correct power supply. Read the brick and make sure it has the same polarity and voltage as the adapter for your laptop.

Remove All External Devices

If you keep external devices such as a smartphone, a USB external drive, mouse, printer and anything else attached to your system while charging, it will take longer for your battery to reach 100%. Make sure you disconnect all of those devices so your system won’t be competing with all the other electronics.

Check Your Connectors for Dirt or Damage

If your laptop has a modular battery, remove it then check for any damage or to see if it needs cleaning around the contacts and inside the battery compartment. Also, check if there are any dust particles inside the charging port that might be preventing the battery from charging.

Check for BIOS and Chipset Driver Updates

Sometimes your system might be overdue for an update for components such as your BIOS and Chipset. Updates can help resolve bugs that might be preventing the battery from charging efficiently.

Press and Release Power Button Reset

Sometimes unknown glitches can prevent the battery from charging. An easy way to fix it is to power down your computer, hold down the power button for 15 to 30 seconds, plug in the AC adapter, then start the computer.

Disable Apps and Check Battery Usage in Windows 10

Going back to Windows 10 a bit, recently, I noticed my Surface Pro was taking an unusually long time to charge and the fans started to rev up. Little did I notice the culprit was right there on my Taskbar all along. Slack’s Windows client was waiting in an attempt to connect to the Internet. So, checking your apps to determine whats running in the background can help you not only conserve battery life but limit what prevents it from charging faster.

There are a couple ways to do that. Open Start > Settings > Privacy > Background apps. Scroll down then toggle off the apps that might be preventing your device from reaching a full charge.

Still in Settings, open System > Battery > Battery usage by app. This will tell you which apps are using the most battery and you can make a decision what to do, whether to let Windows decide if it should run in the background while not sacrificing battery life.

Replace Charger or Battery Module

Ultimately, if you don’t see any improvements after trying all the above, then it’s maybe best that you replace either the charger or battery itself. This will require contacting your laptop manufacturer and placing an order. Batteries and the chargers are not necessarily cheap, especially if its an older system. But, if you have no choice, its something you will just have to do to get your system back in working order.

Thanks for the very detailed reply to my question. I actually have newer laptop symptoms after testing it earlier and am wondering if it helps solve the problem more.

Earlier, I tried removing the battery again since it wasn’t charging anymore. I plugged my laptop in directly without the battery and saw that it still has that fps drop that I was talking about. Now when I fire up games without the battery when I’m in the home screen of that particular game it’s all good and still showing signs of fps drops but when I try to play after loading and transitioning to actual gameplay it suddenly shuts off. Does it still have the same problem as mentioned above?
