    I have an Asus X550D laptop, had it about 16 months. A couple of months ago while using it i heard a loud pop after which the laptop switched to battery mode. I tried the power supply in another compatible laptop and it wouldnt work. I tried a compatible power supply in my laptop and it worked. I changed the fuse in the plug for my power supply plugged it into my laptop and it was fine for about a week befor it went pop again. I replaced the fuse, and as soon as i plugged it into the wall it blew again. I took a trip to maplin and bought a new power supply. A universal one with different power settings and changeable ends. This worked great about 6 weeks until this morning when streaming a film from the laptop to the tv , it went pop. The fuse had gone so i replaced it but as soon as i plugged it into the wall it went again, with a flash in the power supply.

    Any ideas what is wrong with the laptop that is damaging the power supplies? I can go buy another power supply but there isnt much point if my laptop is gonna keep destroying them.

    What capacities were the original and universal power supply? It looks like the X550 comes with a couple of different capacity adapters for different configurations so was everything sealed in the box or was this a refurb/open box purchase?

    Do you leave the battery in the laptop when you're using it on mains?

    It was a brand new sealed box. The battery cannot be removed from this model.
    The original power supply was a 90w, 19v 4.74 output, matching the sticker on the underside of the laptop.

    I noticed when searching for the replacement last time a slightly different power supply seemed to keep coming up on the searches i was doing for my model of laptop so i went with a universal one that could match exactly the laptops requirements.

    Since posting this thread i have had that universal one replaced for another universal one that has a higher power rating (125w) but automatically scales to the requirements. Hopefully this one lasts but I still feel there must be a problem with the laptop.
