Anyone know where Lenovo g550 cmos battery is located? How do I get to it ?

Assuming your battery is the proper spec, some inexpensive aftermarket batteries don't work well with laptops, Take a look at this forum : http://forums.lenovo.com/t5/Lenovo-3000-and-Essential/G550-Battery-Won-t-Charge/td-p/324357 AND this: http://forums.lenovo.com/t5/Lenovo-3000-and-Essential/G550-Battery-problems/td-p/654103

Replace the battery, it's faulty.

Batteries only have a useful life, then they have to be replaced. Sounds like yours is doing like the ink cartridges, where they register as being full of ink when actually there is no ink in the cartridge.

3 orange flashes means flat battery. If you have a faulty charger or charger socket on the laptop then the battery wont charge or power up with just the charger connected.
Look here:Lenovo

Follow these steps: Restart your computer in MS- DOS mode. When you get to the C:\> or C:\WINDOWS> prompt, type DEBUG and press Enter.A hyphen (-) prompt will appear waiting for you to enter commands. Enter the following commands, pressing Enter after each one. Note: the o is the letter o and stands for OUTPUT. o 70 2 e o 71 ff q After the q command (which stands for QUIT) , enter Exit. Then try to enter your BIOS at bootup. The password prompt should now be gone and you should now have full access to it again. However, you will now be at the default BIOS setttings and may want to change them to your preference.

Try replacing the cmos battery.

Hi sheiladew,

Welcome to Fixya!

The speakers of your G550 are located on the front edge of the palmrest and sound more than adequate for playing music or watching streaming video. We have to note the system's versatility in terms of usage, but it's a downside that it does not have a microphone.

I have included a link that can tell you more information about this product, as well as it's components:
