I am new to repairing electronics, so sorry in advance for any logical errors. My issue is that I am not seeing 3.3V and 5V on any of the ICs that take those voltages. I was wondering where the DC to DC converter is on the motherboard. I cannot seem to find it.

My blade 17 (RZ09-0329) has been through some stuff over the years and the broken screen has now put the final nail in the coffin. I am based in the UK and have located a screen seller on ebay, but it did not work and just shows some pink lines (of which I will get a picture of the next time I have it). The keyboard has a few broken keys and missing keycaps so I am wondering if I should get a new unit (~100GBP) or fix it myself. The last any possibly most crucial part is on the board. I have noticed that a very small fuse or resistor has been chipped off on the board near the power connector. There are no scorch marks so I am guessing it was me who knocked it off when I took the keyboard out. I have attached an image of it.

Here are my questions:

• Is there any good repair shop based in the UK which can repair the board component?
• Is there a cheaper alternative to getting a new keyboard unit?
• Has anyone found schematics for razer laptops of know if razer publishes them?
• Is there another option for me to get my screen fixed other than going back and forth with a seller testing screens and eDP cables?

Thanks for your time and all the best!

The board image (red arrow in the upper left points to the component):

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!
