Inspect the adapter for the computer, and ensure that the cord is not damaged or destroyed. If this is the case, please seek a replacement for the adapter as whole. If the cord is not damaged, then reinsert it into the charge port, and remove any other physical connections with the computer. Also, be sure that the AC adapter is connected directly with the wall socket, and not running through any surge protectors or extension cords. If necessary, try and use another device from the same power source, to be sure that the socket is providing power.

Disconnect the computer from the charger, and remove the battery. Proceed, with battery and connector still out, to press the ON button for 5 seconds. Reinstall the battery, and attempt to turn on. Connect the charger, and attempt to turn on the computer.

Please reference further wiki pages to determine how to properly remove a battery.

Computer fails to hold charge for long periods, or must be plugged in at all times.

Be sure that you are not demanding too much of your computer or system at one time. The projection of battery life is directly dependent on the amount of energy the system thinks it will need for the task at hand. Therefore, make sure you are not running too many system-intensive tasks at the same time. You may also turn off the Bluetooth setting, if not being used, or turn down the screen brightness to improve battery life. Finally, you may access the power management settings and change them to whatever settings will help with the battery.

Ensure that the battery is properly connected and placed in the computer. To make sure of this, merely remove the battery, when the computer is not on, and then place it back into its place. Bear in mind that the computer is unibody in construction, and battery removal will be intensive, if one needs help, please reference wiki pages for instructions, or contact Lenovo directly. This will fix the issue if the battery somehow had become disconnected from the rest of the system. If this still does not yield results, you may want to swap the battery to a different, but similar, system, and see if it works properly. If it does not, then replacement may be the only solution [Insert link here].

Inspect the AC adapter to be sure that it is not damaged or broken in any fashion. Further inspect the charging port and clean out any dust or debris in the area. Remove any other connections such as USB cables, this way the charging cable is the only physical input to the system. If the adapter is damaged, it will need replacement, and if the port is damaged then consultation of a computer repair service is in order.

If the battery is still not capable of holding a charge, it may become necessary to replace the battery. Simply purchase a new battery and place it in the appropriate position. If this yields nothing, the system or computer as a whole may be at fault, and then other steps must be taken. Again, be careful around the uni-body make of the machine, and ensure that all steps are properly observed [Insert link here].

You have trouble listening to sounds on your computer

Test the audio through the computer speakers, then test it using headphones. If the laptop can not recognize the headphone when plugged in. You will then need to reinstall your audio driver. Make sure the audio jack is fully inserted in the laptop. If the audio is only distorted while listening on the headphone, the audio jack or the headphones may be broken. This will warrant a replacement.
