If your laptop is no longer under warranty and will not turn on as a result of a water spill or something similar; don't write it off... there may be hope; and you may be able to bring it back from the dead on your own...

Last year, I bought a new laptop from a big name company.  Recently, I came home to find that it wouldn't power up.  When I asked my wife, she said the baby grabbed a cup of water that was sitting next to the laptop and wouldn't let go.  Naturally, the water spilled all over the computer.  Obviously my fault for leaving it where it shouldn't have been; but most of us have done that at one time or another, right?

My wife attempted to clean up the water, but it was too late... the laptop wouldn't turn on.  The power light lit up, the hard drive light turned on briefly and you could hear the hard drive just as briefly; but then everything stopped.  The screen wouldn't show anything through that process.

Since I didn't have the original receipt, and I'm currently overseas, I thought I was about to face a healthy repair bill at the very least... and worst case, I was facing the possibility that all data could be lost.

When I consulted a tech-smart friend of mine, he advised me that the newer laptops are built with circuitry that protects them when such an event occurs.  He said they shut down until the cause of the short (in this case, water) goes away. 

Armed with this knowledge, I decided to take matters into my own hands.  After letting it set for two days in the hopes that things would dry out, I bought a can of compressed air, and dismantled the laptop one screw at a time, carefully noting where each screw came from, so I wouldn't forget when I put it back together.  I removed the hard drive, the battery, the disk drive, the fan, and the keyboard.  I popped out the RAM and also removed all of the screws on the bottom, which enabled me to open up the bottom half (opposite the screen) enough to enable me to spray air inside.

I then sprayed air in every open area, reseated the RAM and put it all back together.  Then I crossed my fingers and pushed the power button... VIOLA!!  It worked!

Please note that this was a last resort prior to paying the big bucks for recovery; and you may want to think twice before going this route... but it did work for me... for the cost of a can of compressed air.

Good luck!
