I was able to get the serial number of the equipment, it is the following:

1249419A00081

I can send you the QR code that is printed on the motherboard: M210404005844#XU133UR720-U50E.

It's not very clear because the label is quite faded, but I'm sending you two photos. If they don't help, let me know if I can find the serial number somewhere else...

Hi colleagues, today I'm here to discuss a topic. I'm hoping to see what you guys can recommend, or rather, how you would carry out this repair...

This is an Exo Smart XL4 laptop, with the XU133U REV 7.2 motherboard.

A customer brought it to me because it suddenly stopped recognizing his HDD. What happens is you turn on the computer and this screen appears:

The computer is an Exo Smart XL4 H3548. The motherboard is a XU133U Rev. 7.2. I'm attaching the BIOS I extracted from the motherboard:...

Hello, good afternoon, my name is Leandro, and I own a laptop repair shop. I started doing all this a couple of years ago, and fortunately, life allowed me to dedicate myself fully to this, which is what I'm passionate about. I'm from Córdoba, Argentina.

A big hug to everyone, and thank you for accepting me into this wonderful forum.​

Hello, good morning. I'm having the same problem with the XU133U Rev. 7.2 motherboard; it doesn't recognize any HDD. Could you please provide me with the BIOS file that worked?
