I recently purchased a replacement battery (Betty, RZ09-0102) from iFixit for my Razer Blade 2014 laptop (model RZ09-0102).

After carefully following the iFixit installation guide, I am experiencing the following issues:

- The first time I used the laptop unplugged after installation, it lasted approximately 1 hour before shutting down. Since then, the battery only lasts approximately 5 minutes before the laptop shuts down abruptly.

- upower on Linux Mint reports 0 Wh and 0% at all times, even after several hours of charging

- The charge_now value in /sys/class/power_supply/BAT0/ always returns 0

- The laptop works fine when plugged into AC power

I have already tried the following troubleshooting steps:

- Reconnecting the battery connector multiple times

- Performing full charge/discharge cycles

- Updating upower

- Multiple reboots

I am not sure whether the battery is defective or if there is a compatibility issue with Linux Mint. Could you please help me diagnose the issue and advise on next steps?

I also ran i2cdetect -y 0 on the SMBus I801 adapter and got no response from the battery BMS — the grid shows only dashes, confirming the BMS is completely silent on the SMBus.

Thank you for your help.

Best regards

I have removed the old one and it is the one that went directly below the charging port in the photo

The next day, the same thing happened, where it stopped going up, but this time I just did the EC reset, and it lowered the charge by 10%, but allowed it to charge like normal.

Now, today, the same thing has happened when it got stuck and won't charge past 57%, but this time, the EC reset has not done anything, and restoring the drivers hasn't either. I have charged it for a while, then let it completely die, and then charged it back up for 2 hours to try to calibrate the battery, but that has not worked. Additionally, I performed another battery report, but this time the storage capacity is showing only 10% of the design capacity.

I have taken the laptop apart, and the connector seems to be seated correctly, and the battery is not swelling. As I am writing this, it seems to have fixed itself and is charging, but it is quite slow. But running another battery report, the capacity remains at exactly 10%.

I have no clue how to even approach this, as I have tried everything.
Any suggestions would be great

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.

Additionally, I am having trouble discerning where this battery connects to the motherboard, as there seems to be no connection visibly streaming from the battery which connects it to the rest of the laptop.

In scouring the internet, the only lead I have found comes from a comment on this thread, which mentions a comment that user had read elsewhere on YouTube which states: "There is a pull tab to the left edge of the battery. It looks like part of the frame but if you can lift it, just pull it straight out - it will come out as one piece."

When I examine the laptop battery inside the chassis, I do see a tab which I am able to lift up slightly on the left side of the battery (pictured below). However, I do feel a little bit nervous about pulling on something next to this giant pillow based off a third-hand account. Does anyone with experience replacing batteries know that this is the correct solution?

Since I've been using if for over 3 years now, I figure it would be wise to try applying new thermal paste to the CPU (I'm not sure if the discrete graphics card inside would also have thermal paste to replace, but if so then I'd guess it would be useful to replace that as well).

I have some experience following pre-existing iFixit guides, but certainly wouldn't know where to start on this task given that I can't find any information online about how the internals of this machine are laid out. If it would be useful, I can supply a picture of the inside after removing the back panel.

I restarted, plugged in and unplugged, opened it back up and made sure everything was secure. It seemed to be. I restarted again, etc. I've checked Device Manager and tried to update the drivers -- everything's up to date. Scanned for new devices -- nothing. Clearly the battery is delivering power, and I took my time browsing the internet, taking screenshots, etc.

Any ideas what's up? Could the battery have a bad controller of some kind?
