Uploading images to laptop
By default, Windows uses a 32bit FAT when formatting which is NOT compatible with most cameras. I'd suggest sticking to using the camera menus for formatting a card, unless the camera can't format one (then, if you must use a PC for formatting, make SURE you select FAT as the File System Type). I'd also recommending formatting again with the camera menus before using a card if you ever do need to format one with a PC.
As for your problem with the laptop seeing the card, it could be any number of things. It's more likely related to the USB drivers. Many users report intermittent problems with USB connectivity after upgrading to SP2.
A frequent solution that sometimes works is removing all devices drivers related to USB (My Computer, Properties, Hardware, Device Manager). Then, rebooting and letting Windows find and reinstall the drivers again. Sometimes, updating these drivers can work, too.
You may also be seeing a conflict between other USB devices and drivers. For example, sometimes HP Printer Monitor software conflicts with USB connectivity to other devices.
You may also want to try a different USB Port.
If all else fails, consider a Card Reader (they're very inexpensive now -- you can probably pick up a USB 2.0 card reader for around $20.00 locally). With a laptop, you may also want to consider a PCMCIA based reader.
