Best Of

Thank you for the helpful discussion here. For what it's worth, I have an Acer Intel system that was new in 2023 that seems to be in the same situation. It has the February 2026 BIOS on board but still am getting this status message:

"Secure Boot is on, but your device is using an older boot trust configuration that should be updated. There is not yet enough data to classify your device for automatic update. "

>Good thing I bought it from a physical store, so I can return it. I’ll let them check the issue or ask for a replacement.

Definitely the best solution!🙂

Hello. I have the exact same issue with my Acer Aspire 7 (A715-59G-55GC) as this person: https://community.acer.com/en/discussion/737879/after-update-win11-black-screen-no-logo-acer-aspire-7

After installing the latest Windows 11 updates along with some Acer/driver updates, the laptop restarted and now only shows a black screen.

Current symptoms:

• Power button lights up
• Keyboard backlight works
• Fans are spinning normally
• Internal display stays completely black
• External monitor through HDMI also shows no signal
• No Acer logo appears on startup
• Cannot enter BIOS using F2
• Waited around 30–40 minutes, but nothing changed

Things I already tried:

• Forced shutdown by holding the power button
• Power reset (unplug charger and peripherals, then hold the power button for 30–60 seconds)
• Tried booting again multiple times
• Checked for a battery reset pinhole, but I can’t find one on this model

I really don’t recommend updating this laptop to the latest Windows 11 version, as it seems to corrupt the BIOS after the system update.

Good thing I bought it from a physical store, so I can return it. I’ll let them check the issue or ask for a replacement.

Hello, same issue here. I really don’t recommend updating this laptop to the latest Windows 11 version, as it seems to corrupt the BIOS after the system update.

In my case, I let the laptop finish updating, then suddenly the screen went black for a few minutes. I tried force restarting it, and now it only powers on — the keyboard lights up, but the screen stays black.

Hello. have Acer Aspire 7 : A715-59G-55GC.

After installing new Windows 11 updates and some Acer/driver updates, the laptop restarted and now shows only a black screen.

What happens:

• The power button lights up.
• The keyboard backlight works.
• The fan is running.
• The internal screen stays completely black.
• HDMI external monitor also shows nothing.
• I do not see the Acer logo.
• I cannot enter BIOS with F2.
• I waited about 40 minutes, but nothing changed.
• I tried holding the power button to force shutdown.
• I tried the Acer power reset: unplug charger and all devices, then hold Power for 30–60 seconds.
• There is no visible battery reset pinhole on the bottom or sides of the laptop.

It looks like the laptop does not pass POST, or maybe the BIOS/EC/firmware update failed.

What can i try to do to live my Acer ?

Laptop bought ~ 5 month ago, but I lost all docs and check about shopping :(

Hi Silko,

The blank Drainage profile in the Battery Report and charging stuck at 74 % aren’t signs of a missing battery — they’re symptoms of using the wrong power source.

• You mentioned running the Aspire Go 15 through a ThinkPad Universal USB‑C Dock with a 90 W charger. This is below the ~100 W PD requirement for the AG15‑71P.
• With only 90 W available, the embedded controller negotiates partial charging and halts early. That explains why the battery never logs discharge cycles (blank drainage profile) and why wear stays at 0 % — the pack is detected but never actually used.
• If the battery were not detected in BIOS, you’d see 0 % with a flashing amber LED. Instead, you see 74 %, which confirms the pack is present but not charging fully.

So the issue isn’t a wrong battery type — the AG15‑71P uses the correct AP23A7L‑series pack — but rather the dock charger being under‑spec and incompatible for charging. The laptop expects either the original Acer barrel adapter or a certified 100 W USB‑C PD charger directly (not a universal charger but a laptop charger with a fixed 5A thick USB-C cord)

Next step:
Use the original Acer adapter or a proper 100 W PD charger without the dock. If the battery has already latched into protection mode from repeated under‑power use, Acer Support may still need to replace it, but avoiding the dock charger is essential to prevent recurrence.
