Lenovo ThinkPad W540 Battery
Your Lenovo ThinkPad W540 battery allows you to move freely about which gives you the opportunity to use it anywhere you please. The larger the battery, the longer it will last when fully charged. Getting a battery with a higher amp rating is OK, as it just means the battery will last longer. What is truly important is the connection type and physical size of the battery. Not all batteries are the same, make sure and double-check the part number of the new battery and compare it to the old one.
Key clues of an inadequate primary battery
- The laptop does not run longer than one hour before it shuts itself down
- The Lenovo laptop is unable to boot up when it is unplugged
- The laptop battery gets puffy and looking like it is going to burst
