Chosen Solution
I recently bought a BETTY4(3ICP4/56/102-2) battery to replace in my Razer Blade 14” (2017). I followed the iFixit guide and managed to have it power on to desktop until it drained (battery arrived almost empty). The battery isn’t charging. I’ve tried refreshing drivers, checking connections, and battery optimisation instructions. I’ve reached out to the seller, but any advice or tips would be great please!
Don’t invest any more time in formatting, drivers, or anything else within the O/S until you’ve already ruled out it’s not a software/hardware issue. There are specific components between your power adapter and the motherboard which make decisions about charging and using your battery. My best guess is that there is a hardware issue in one of these components. If your laptop has a built in hardware diagnostic tool you can try running that, but they have limits on their effectiveness.Some potential options if you still want to try some things- Update firmware on laptop- Try power adapters rated for higher wattage- If the power-port on the motherboard is removable, you can try replacing that one part and see if that’s the culprit.
