Asus X555L - systemic problem?

[katfish]

I have two of these in my shop, from two different customers. And both have the same problem. Hard drive sometimes is not seen on power up.

Wanted to see if anyone else has encountered this. I've tried a new bios chip with a clean dump. And also tried the drive in an adapter plugged into the cdrom port.

Yea, I considered maybe IO board ... might go ahead and order one to see. Not much to it really though. Under the scope, all the solder joints look good at the connectors. But reflowed it anyway. Think I'll go ahead and get one to check out.

Btw this is common problem on this model, but this model is in warranty

Hi,

It is probably the IO and Main board connector is faulty... Clean it using surgical spirit or some other Oil free contact cleaner.
