简介

A laptop battery's performance naturally decreases with time, so replacement is necessary to maintain high performance and charge duration.

  1. Power off and unplug your laptop before you begin.
    • Power off and unplug your laptop before you begin.

    • Turn the laptop upside-down and remove the following screws using a Phillips #0 driver:

      • Two 9.5 mm screws in the middle of the back edge, and one 9.5 mm screw in the right edge

      • Two 4.3 mm screws in the back corners

      • One 17.5 mm screw at the left edge near the optical drive

      • Three 4.3 mm screws in the front edge

    screw assignments are definitely wrong. I swapped the red and the green, as per comment above, and kept the blue as-is.

    Thanks everyone. It does seem like someone got their screws mixed up when they wrote this guide. I’ve made some changes as you all suggested, so the screw placements should be more accurate now. If anyone with this laptop could verify the screw measurements with a digital caliper, that’d also be very helpful.

  2. Use the plastic opening tool to separate the keyboard plate cover from the bottom cover. In order to do this, insert the plastic opening tool in between the keyboard plate cover and the bottom cover, then slide along edges to pry open.

    • Locate the three ribbons connecting the keyboard plate cover to the bottom cover.

    • Invert the laptop in order to gain access to the ribbons.

    • Remove each ribbon by flipping the small white plastic flap up and gently pulling on the ribbon.

    Don't remove the ribbons, just move the keyboard slightly forward to remove the old battery and insert the new one (just make sure they are all connected when you put it back)

    • Now that the ribbons have been detached from the bottom cover, carefully remove the keyboard plate cover. Once it has been removed, place it in a safe and moisture free area so it does not get damaged.

    Is painting your nails crucial for step 5?

    Yes and you have to put lotion on

    Now, that is a stupid question! Of course! As I am working on 551M, I naturally have to have nails painted orange, with blue accents!

    • Remove the battery from the laptop by applying pressure on both ends and lifting it out of the case.

Thank you for the procedure. I never worked with ribbon connectors like that; perhaps a few words or pictures that shows connecting procedures may be helpful to others. How far in ribbon must be etc. Thanks again, good job.

Hi there! I have replaced my battery but the new one does not charge. Does anyone have any idea on how to solve it? I have tried several possible solutions found online like removing the battery (completely) turning on the CPU and then off, placed the battery and restarted. Pressing the power button for 15s or 60s and then turn on the CPU.... well.... Loosing hope here.... :( Help!

Thank you, Josh. Clear instructions. The most difficult part for me was to re-connect the "ribbons", since I don't have nimble fingers. I actually used a plastic toothpick to help doing this :)

Thank you for the explanatory procedure, however my battery is a 11,1v and I find 14,4v only on the market. Do you think it will damage my pc?

I did not have to disconnect the ribbons. I was able to scoot the keyboard away from the screen/hinge (about two inches) and pop the battery out.
