How do i restore my lenovi G550 to factory settings without a cd? the laptop is installed with windows 7

Hi,

All you need to do is removed the battery and unplugged the charger then press and hold the power button for 15 seconds then connect the laptop directly to the power outlet without using the battery just for the meantime then press the little button near the power button which has a drawing of an arrow going to the lef or soing down like a horseshoe or headset, press that button then you will see there One Key Recovery, choose that one then choose restore from factory default, then choose restore from initial back up then click OK and Start, that will restore your computer from the factory default, if this button doesnt work, contact lenovo to asked for a cd, its free and you just have to pay for the shipping which is $10.

Hope this will help...

Try clicking on my computer, looking to see if there is a D: drive or some other and searching it for a setup.exe. Usually the newer laptops have all the drivers and resetting software in another partition of your hard drive.
