Hi everyone,
I have a Razer Blade Pro 17" (2020), model RZ09-0329x and recently the battery swelled up. Now the laptop won’t power on at all, even when I connect it to the original AC adapter.
I couldn't find a replacement battery anywhere, and since I urgently need to use the laptop, I tried disconnecting the battery connector completely to see if it would run just on AC power. But unfortunately, that didn’t work — it still won’t turn on.
While inspecting the inside, I noticed a small circuit board between the two battery cells, near the bottom cooling fans. It seems to be a Battery Management System (BMS) board.
So my main questions are:
- Is this BMS board required for the laptop to boot even when the battery is removed?
- Is there any safe way to bypass it or trick the system into running directly off the adapter?
- Has anyone here successfully powered this model without a battery? Any tips or schematics would be a huge help.
Thanks in advance for any help or suggestions!
