Introduction

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

Remove the middle two 9.5 mm Phillips #0 screws from the top edge and the one 9.5 mm Phillips #0 screw from the right edge of the computer case with the Phillips #0 Screwdriver.
  • Remove the middle two 9.5 mm Phillips #0 screws from the top edge and the one 9.5 mm Phillips #0 screw from the right edge of the computer case with the Phillips #0 Screwdriver.

  • Remove the two 4.3 mm Phillips #0 screws from the upper corners of the case with the Phillips #0 Screwdriver.

  • Remove the one 17.5 mm Phillips #0 screw from the left edge of the case using the Phillips #0 Screwdriver.

  • Remove the three 17.1 mm Phillips #0 screws from the bottom edge of the case with the Phillips #0 Screwdriver.

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

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.

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. 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.

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!

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?
