I have a problem with my sony VAIO, I have my battery inserted in my laptop and even though it acts like there is no battery (it's not charging, I am not able to turn on the laptop when it's not pluged in). I guess it started after I had turned off the "VAIO battery care" that limited battery charging to 80%...
The battery may be dead. How old is it? A battery has a "lifecycle" of sorts, just so many charge/discharge cycles.
I bought my VAIO in April this year... I hope I didn't kill it somehow :D
Check the battery connections, maybe use a little Electronic Contact Cleaner or Isopropyl Alcohol on the contacts, Check for damage connections, insert battery fully. Make sure the Laptop is UNPLUGGED when inserting or removing battery. If you have a Multimeter you can check the battery DC volts. IS the laptop Cord/transformer "Brick" getting hot/warm?
You have done this right?http://www.youtube.com/watch?v=LY2A3pVby...

nope..that's just what happens with batteries that are older, tired, and dried out..

This is not a problem, this is a designed function to increase battery life. To adjust this, go to "vaio control centre", and then power management. Inside this is battery care, here you can adjust the settings or de-activate this function.

If you replaced the battery from one of the many sites that promise complete compatibility with the original OEM battery with specs that meet or exceed those of the OEM, you're on the wrong track. They don't work in my experience. Sony has a proprietary chip in their battery packs that identifies it as an "original" The battery sites state that you have to update the BIOS drivers to make it work and if you have Windows 7, it will be problematic. I've gone through this several times, and what I've had to do is do a restore to a point prior to installing the software that the battery site provided. Although I received a notice that the restore was unsuccessful after it had been run by a system restore CD that you should make; I received notice that the restore was successful after reboot. I then ordered the battery from Sony, installed it, and all is well. Best advice is to be very circumspect in getting batteries from any source that says they are brand new and are completely compatible. A place I know to go to replace bad cells is www.batteryrebuild.com or batteryrefill.com (same site). They replace the cells, leave the original chip, and the computer sees it as an 'original' Sony battery.
