Short expert summary tied to the existing replies: reports the same black-screen/fan-spin-then-stop behaviour with both the old and the newly bought battery; rightly flagged battery quality and suggested a Windows update. The pattern described — power LED on, fan spins briefly (about 2 seconds) then everything goes quiet — typically happens before Windows or drivers load (during POST/power-rail initialization). That makes a bad battery or a recent MS update less likely causes; this pattern more commonly points at the power/board side (adapter, DC jack, motherboard fault, or a short) or a display/backlight failure.

Practical checks (in order):

  • Hard power reset: remove AC and battery, hold the power button 30–60 seconds to drain capacitors, then try booting with AC only.
  • Isolate power: test with AC-only and with battery-only (if possible) to see whether the adaptor or battery is implicated.
  • External video and backlight check: attach a VGA/HDMI monitor to see if any picture appears externally. Shine a bright flashlight at the laptop screen to look for a very faint image (backlight/inverter issue).
  • POST indicators: press CapsLock/NumLock to see if LEDs toggle and listen for beeps — no LED/beep usually means POST never completes. Observe any power-LED blink patterns; they can be diagnostic.

Deeper, cautious steps:

  • Reseat/try RAM sticks one at a time and in different slots. Remove HDD/ODD to force a clearer POST response.
  • Check the DC jack for looseness and verify adapter output with a meter or a known-good adapter. If comfortable, reset BIOS by removing the CMOS battery (power removed first). Always unplug power and battery before opening, use basic ESD precautions, and consider warranty implications.

If none of these reveal the fault, the machine likely needs board-level repair (power regulation, GPU or mainboard). Given that both batteries behaved the same, start with the hard-reset, external-display test and RAM reseat before pursuing paid diagnostics or parts replacement.

Where did you purchase the battery from? From your description, I think that the battery is non-functional. Don't purchase cut-rate brand-x batteries from sources you aren't sure of. Personally, I do purchase brand-x batteries for my laptop, phones, etc; however, I DO purchase them from sources I know will stand behind (and not too far behind) what they sell, with liberal return policies.

I wish I did know the cause as I also have an acer and two days ago same problem - I am wondering if it's a download from MS as same issue not long ago and that wa caused by an automatic download. I am considering "Apple" as I am constantly having issues with MS updates causing issues with my computer:))
