Is there a protective sticker/cover over the laser? (It's not really a laser)

Details of the camera make and model may help find your problem. That being said the cause is probably one of two things, the 32GB SD card is too big, try a smaller card and see what happens. Also as odd as it sounds, some devices (phones, cameras, tablets) do not like certain brands of SD cards. Also SD cards have a switch on the side, make sure it's in the "Unlocked" position. The best thing to do is go to the manufacturers website and check their specifications on SD card compatibility. But sometimes a Google search of the cameras make and model SD card compatibility can usually answer the question from owners of the same product.

There are two steps I would take to troubleshoot this. First if you haven't already, check to see if this is a known problem, Google it a bit. After that if your on your own "oldturkey03" has you on the right track. With the car running, the voltage at the battery should be 14VDC or a bit more, this is most easily checked with a multimeter (if you don't have, or know someone with a voltage meter, try going to your local autoparts store, they may have one to test it for you). If you do have 14VDC while running (12VDC when car is off), then check your battery cables for corrosion, are they tight enough? Also follow the cables from the battery to whatever they connect to next, the negative (Black) cable will probably bolt to the engine, with several other wires bolted to the same place, make sure it's tight. From there you can start looking at all the junction points the Positive cable makes, all the way back to the fuse block. This will include alternator and starter connections. The Negative cables need to...

I am assuming the 2 free slots are the SATA3 drive slots. So if you want to simply add an SSD for memory expansion, all you do is open the back, and pop in the new SSD (You will need to purchase a HDD Caddy for the new drive). The new drive should automatically show up in Windows. I have had great luck with Samsung EVO SSD's and they are reasonably priced at Newegg: http://www.newegg.com/Product/Product.as... As for a guide, this is the closest I could find, as I do not own this laptop, also they have a link for the HDD Caddy: https://www.youtube.com/watch?v=4TD9eV9x...
