Lenovo E40-30 Battery
Your Lenovo E40-30 battery allows you to move freely about so that you can use it anywhere you please. Because no battery is the same, be sure to check the model number and compare it to the old battery. It is OK to buy a battery with more milliamps, it simply means it is a stronger battery. What is important is the connection type and physical size of the battery. The more power the battery has, the longer it will last on one charge.
What happens when my Lenovo battery is dying?
- The laptop does not turn on while not connected to the AC adapter
- The laptop lasts less than an hour before it dies
- The laptop battery has its case swollen and looks like it will explode
