Exclamation Moist Mini - 09-29-2009, 01:07 AM

Somehow my fiancee's A90 got some water spilled on the keyboard, and she didn't notice until the machine rebooted itself. I quickly removed power and begun disassembly to check for damage. Here is what I found




The A90 is currently drying out on the table, and I was thinking of trying the white rice trick. Do you guys think it could be salvaged? I was planning on running to the store for some Isopropyl Alcohol and q-tips to try and clean it.

Yeah. I'm not really sure what the fix here is. I might completely remove the mobo to ensure there is no more moisture under it. She's pretty upset about it.

I suppose we could send it back to Dell and pay whatever they want to repair it. How easy is it to get your hands on a Mini9 / A90 these days?

remove the board and soak that end in isopropyl alcohol (as pure as you can get it, pharmacies are usually best) for a little while, then let it dry out. Might even try scrubbing that section with an old toothbrush. Then, let it air dry overnight. I have had good success with cell phones and such this way.

OKay, the board is out.





I flipped it over and noticed that there is no corrosion on the underside, hopefully that is a good sign.

I'm going to the pharmacy right now to look for isopropyl alcohol and a soft bristled toothbrush. Do you think it would be worth placing the board in an airtight container with white rice or Desiccant packet to remove the leftover moisture from the alky bath?

how long should it be soaked in isopropyl?

You can still order a new A90 from Dell. When I looked last night, it was $239 for the base with 8gb ssd.

I just returned from the store. The pharmacist assured me that the highest concentration of isopropyl i will find around here is 91%. So i bought a bottle and a soft bristled toothbrush.





Visually it looks 1000x better, all of the corrosion came off with minimal effort. Currently the board is sitting on a cloth with a modified 120mm PC fan gently blowing air across it to aide in the drying process.

Thoughts?

True, I just looked an saw a few available. Anyone know what Dell would charge me to repair this one, if this doesn't work?

Since the netbook was already in pieces, it gave me an opportunity to install the Pretty Pink lid I bought her a while back. Hopefully this thing works when its all said and done. I'm going to bed now, I'll update you guys tomorrow evening.

Good luck!!

It seems to me as if you have taken all of the proper steps to ensure the best possible results. Cleaning the corrosion with alcohol and allowing the board to dry out is your best option.

rice is great when dealing with a freshly wet problem, but the alcohol will draw out moisture and clean the corrosion, and then dry out on its own. The fan will help. It should technically be dry within less than an hour, but waiting overnight is safer. Other than that, you should be set. Let us know how it goes.

Should I be concerned that the machine rebooted itself before we discovered the moisture?

Thanks for the encouraging words, guys.
