Hello everyone!

I want to express my sincere gratitude to user
Sparo for helping me unlock the BIOS! 🙏

Laptop: Acer A315-22G (AMD A6-9220e, Radeon R4)
Problem: BIOS was password-protected, and the
password didn't work.

After contacting Sparo, I received a hint code
and the universal password 12345, which successfully
unlocked the BIOS. I immediately removed the
password (Set Password → empty field), disabled
Secure Boot, and configured boot from USB.

If anyone needs a BIOS dump for this laptop
(Acer A315-22G) — feel free to download the
dump I attached. It's working, password 12345
works, BIOS is unlocked. Can be used for
restoration or chip replacement.

Thanks again to everyone who helps the community! 🙌

❗ NEW PROBLEM (not related to BIOS):

✅ Laptop works stably with the original
soldered 4GB DDR4 RAM
✅ Decided to add an 8GB stick for upgrade
✅ RAM stick: KINSOTIN DDR4-8GB-NB-3200MHz
(P/N: N432CXBMB, Made in China)

Photos attached.

❌ Problem:
- I insert the stick into the free slot (until
it clicks, latches closed)
- I turn on the laptop: fans spin, indicators
light up, BUT NO SCREEN BACKLIGHT — screen
is completely black
- Waited up to 9 minutes (for memory
initialization) — didn't start
- I turn off, remove the stick — laptop
immediately boots normally with original 4GB

🔧 What I've already tried:
- Reset BIOS to factory defaults
(Load Defaults)
- Disable Secure Boot
- Install official drivers from Acer website
(Chipset + VGA)
- Clean RAM stick contacts with an eraser
- Reset EC (power button 60 sec without battery)

💡 Questions to the community:

1. Is the 3200MHz KINSOTIN RAM stick compatible
with AMD A6-9220e processor?
- CPU: AMD A6-9220e (1.6 GHz Base /
up to 2.4 GHz Boost)
- Memory controller officially supports
DDR4 up to 2400MHz
- In practice, system runs at 1866-2133MHz

2. Could the problem be with the SPD profile
or timings of the Chinese RAM stick?
- It's known that budget sticks sometimes
don't correctly provide data to the controller
or don't support downclock below 2666/2400MHz,
causing older AMD APUs to fail POST initialization.

3. Is it worth trying to update BIOS or edit
SPD timings via programmer, or is this a
hardware incompatibility, and easier to return
the stick / look for DDR4-2400MHz from trusted
brands?

📋 Full laptop specifications:
- Model: Acer Aspire 3 A315-22G
- Processor: AMD A6-9220e (1.6 GHz Base /
up to 2.4 GHz Boost, 2 cores)
- Graphics: AMD Radeon R4 Graphics (integrated)
+ AMD Radeon 530 (discrete, 2GB)
- RAM: 4GB soldered (DDR4, runs at 1866MHz)
+ 1 SO-DIMM slot
- BIOS: version 1.09 (haven't updated, have
backup via RT809H programmer)

🔧 Skills: have repair experience, soldering
station, RT809H programmer — ready for advanced
methods if there's a chance.

I would be very grateful for any advice! Thanks
in advance to everyone who responds. 🙏

Hi Sparo!!!

IT WORKED!!! THE PASSWORD 12345 WORKED!!! 🎉🎉🎉

I'm so sorry for the confusion earlier — I must have entered it incorrectly
when I tried before (maybe a typo, or I missed a digit, or the keyboard layout was wrong).
It was totally my mistake! Please forgive me for doubting! 🙏

Thank you SO MUCH for your help, patience, and expertise!
I was struggling with this BIOS password for so long, and you saved me!

You're absolutely AMAZING! My laptop is finally unlocked and I can use it again!
You're a HERO! 🙏🙏

Thank you thank you thank you!!!
Best regards,
Olegst44

You had me doubt it for a split second lol
The important thing is that it's all sorted out and You're welcome!
Enjoy Your unlocked machine 🙏

Hi again Olegst44 ! Remember this is an English ONLY Forum
Take some time to read the Forum's rules > RULES UPDATE for BIOS requests/offers *AVOID BANNING, READ BEFORE POSTING* - Badcaps
Also for the websites you posted, they only work when the hint unlock code is all decimal keys (8 digits, 10 digits) e.g. 81256749 Yours is a hex key 956B1AEE
That said, I don't know why the password 12345 didn't work for you? It's the correct decoded password but I'll look into this again tomorrow

Здравствуйте, Sparo!

Спасибо за вашу помощь!

К сожалению, пароль 12345 не подходит при запросе BIOS.
Сейчас после 3 неудачных попыток ввода моя система показывает Unlock Key Hint: **956B1AEE**

Я уже пробовал несколько онлайн-сервисов для разблокировки BIOS:
- BiosBug.com
- bios-pw.org
- И ещё несколько других

Пробовал много раз с разными вариантами, но ни один не сработал.

Если вы могли бы помочь мне с правильным расшифрованным паролем для моей платы NB8607G02-MB, я был бы чрезвычайно благодарен!

Спасибо за ваше время и поддержку!
С уважением,

Hi Sparo,

Thank you for the password (12345)!
Unfortunately, I still cannot download the file "A315-22G_BIOS_Ver_109.rar" — it shows "Premium supporters get full download access" error even after m1ch43lzm unlocked it.
As you requested, here's my Unlock Key Hint: **956B1AEE**
Any help would be greatly appreciated!

Thank you!
Best regards,
Olegst44

Hi Olegst44 And Thank You for the Unlock Hint !! (This is for my own learning)
Also No need to download anything. I already gave you the BIOS password decoded from your BIOS backup
You can either keep the password, change it in the BIOS settings, or restore to factory settings to clear it
And You're Welcome, See you in the Forum!
