Re: Nitro ANV15-51 Battery detected but not charging, BIOS update blocked by low battery?
Hi JediDoc,
Thanks for sharing the battery report. After reviewing the telemetry and recent capacity changes, a few things stand out:
- On July 25th, your battery’s full charge capacity dropped from 50.6 mWh to 32.2 mWh, and design capacity plunged to 37.5 mWh. That’s a 38% overnight loss—highly irregular for standard lithium-ion wear.
- On July 26th, the report shows no telemetry data at all, which often means the EC couldn’t read the battery’s EEPROM correctly.
- Your BIOS version (V1.26, March 21, 2025) is up to date, so the issue isn’t firmware-related.
The symptoms suggest your battery might be refurbished or aftermarket:
- Sudden non-linear capacity drops
- Charge LED functioning, but Windows failing to register power
- Design capacity and firmware inconsistencies breaking EC communication
If that’s the case, OS and BIOS may block telemetry or charging attempts to protect the EC. These issues can’t be fixed by software—they’re hardware-level failures.
💡 Also, if your Nitro ANV15-51 is less than a year old and you’re the original owner, you might still be eligible for a battery replacement under Acer’s warranty. It’s worth contacting support with your SNID and a copy of the report.
Before trying any flash or recalibration work, I’d recommend replacing the battery with an OEM-compatible unit. Here’s a link to a verified replacement battery: Genuine AP21D8M Laptop Battery for Acer Nitro V 15 ANV15-51 AN16-51 5 AN515-58 | eBay
Let me know if you want help checking the battery’s firmware strings or filing a support request with Acer.

Re: No BIOS update for Acer E5-573G, Is there a newer version for TPM fix?
Go to HelpDrivers as they have the BIOS version 1.37 "bios_acer_1.37_a_a.zip" for the E5-573G laptop, I've included the bios for you, as its not a virus or malware. Good luck and hope this helps you out. As this site is the only viable for old drivers for Acer laptops and desktops. As other bios sites on the web, you would have to pay to get this bios version.

Re: Considering Aspire 5 AG15-51P-51XY — concerns about fan noise & performance
Hi ThomazsG,
Thanks for laying out your experience so clearly—it's frustrating when a laptop doesn’t meet expectations, especially around noise and display. Based on your use case and feedback, switching to the Aspire 5 sounds like the right move.
While the AG15 has its strengths on paper, the Aspire 5 with the Intel i5-12450H should perform better in real-world multitasking, thanks to its higher performance cores and improved thermal design. Given your planned use with an external monitor, you're sidestepping the only real drawback—its slightly dimmer screen.
Also worth noting:
- 🌀 The Aspire 5 typically has more relaxed fan curves at idle and during video playback, especially under updated BIOS settings.
- 🔌 You’ll benefit from a better range of ports, which improves overall usability and external display flexibility.
- ⚙️ For your typical workload—browsing, streaming, downloading—you’ll likely enjoy a quieter, cooler experience overall.
Returning the AG15 while it’s still within the refund window is a smart call. No need to hang onto hardware that feels distracting in daily use. Let us know if you want help fine-tuning the Aspire 5 once it arrives—adjusting power settings or fan modes can really elevate the experience.
Good luck.

Re: Considering Aspire 5 AG15-51P-51XY — concerns about fan noise & performance
If you want an efficient Acer Aspire model laptop for multitasking and video (note that audio in these laptops are all the same) as for best and like Hi-Fi audio you should use a noise cancelling excellent headphone like the Sennheiser Momentum 4 or similar good Hi-Fi headphones and don't rely on any laptop speakers to give you Hi-Fi quality sound, as they are all tinny😁.
If you want an Aspire laptop like that, I suggest that you look at one of the following Acer Aspire released in August 2024 the Aspire 15 range of these models, the A15-51P / A15-51PT / A15-51M / A15-51MT, with the higher end i7-13620H or even the i9-13900H cpu's and with the either 16GB LPDDR5-4800MT/s or 32GB LPDDR5-5200MT/s speed onboard memory. And it comes with a 15.6" Full HD (1920 x 1080) 16:9 ComfyView (Matte) 60 Hz and have a gen 4 x4 lane 1TB M.2 SSD drive and they are a much better choice than the Aspire AG15-51P. have a look at these laptops. Good luck.
