My model was a Dell XPS and fitted perfectly.

A: Hello, the battery size ML1220 is correct but I can not guarantee 100% the connector is suitable for Razer 15 Blade. Can not find the specs of CMOS for this model.

**Q: Will this battery work with an xps 15 l521x?**
A: Please check list of compatible model numbers in the Amazon listing.

**Q: Is this cmos battery compatible with precision m4800**

As described

### ⭐⭐⭐⭐⭐ Revived my Alienware steam machine
*by L***I on 29 May 2024*

Was stuck with a blinking yellow on button, after replacing a faulty power supply that likely took the cmos battery out with it, plugged this in left for 20 mins and it booted right up, got another as a backup in future!

### ⭐⭐⭐⭐⭐ Fixed my problem ❤️
*by I***I on 11 June 2023*

I was having a problem with my Razer Blade 15 where it was in a constant boot cycle. This was annoying and I thought it might damage the hardwares and even the OS. After searching online, many replies suggested that this is a problem with the CMOS bios battery. I purchased it and replaced my old CMOS battery. At the first boot you will see the boot cycle due to bios reset. But after that, the boot cycle issue did not occur again and I am so happy that a small thing like a battery could do it! Highly recommended CMOS battery for ML-1220 type.
