ID: 147681

Description: This is a brief guide for the Li-ion battery...

Steps:

1. Please check the appearance before fixing the laptop. For example: The laptop has been spread by the battery inside (up to 5 mm).

2. This is an optional step. This step can be skipped when users don't want to know the battery status or don't have the software.
3. Check the "cycle times" by battery software.
4. Suggested software: (1) BatteryInfoView, (2) BatteryMon.
5. Background: The number of "cycle times" depends on battery usage. It usually > 0. A Li-ion battery usually has "cycle times" about 500~1000. REF: https://doi.org/10.31224/osf.io/swcyg
6. For example: BatteryInfoView shows that "Number of charge/discharge cycles" is 306 (red box). BatteryMon shows that "Charge cycles" is 306 (blue box).

7. Go to the back side of the laptop.
8. Remove the screw with a "+" screwdriver (the red circle).
9. Number of screws: 1

10. Go to the front side of the laptop. Behind the LCD monitor.
11. Remove the screw with a "+" screwdriver (the red circle).
12. Move to the other side and remove the screw with a "+" screwdriver (not shown).
13. Number of screws: 2

14. Go to the back side of the laptop.
15. Lever the plastic part by crowbar gently.
16. Suggested tools: (1) Crowbar, (2) "-" screwdriver.

17. Rotate the laptop 180°.
18. Remove the screws with a "+" screwdriver (red circles).
19. Number of screws: 4

22. NOTE: Do not break the retaining buckle.

23. Remove the screws with a "+" screwdriver (red circles).
24. Number of screws: 4
25. NOTE: If the battery is severely swollen, you will see the back of the laptop stretched open after the screws are removed.

26. Rotate the laptop 180°.
27. Tear off the plastic sheet (silver) and double-sided tape (black). The main thing is to let the screws hidden underneath show up.
28. NOTE: It is difficult to remove the double-sided tape completely, and some remain on the surface, but it does not affect entire the repair process.
29. CAUTION: This step is a "destructive" teardown and cannot be restored to its original state.

30. Remove the screws with a "+" screwdriver (red circles).
31. Number of screws: 6

32. Rotate the laptop 180°.
33. Follow the direction of the red arrow and open the backside of the laptop from the open side, where the cooling cooper tube can be obviously been seen.
34. The swollen Li-ion battery appears (the white package).
35. CAUTION: If the backside is opened from other directions, the flat cable may be broken or the plug may be damaged (the red circle).

36. Remove the screws with a "+" screwdriver (red circles).
37. Number of screws: 7
38. NOTE: Please avoid flat cables when removing screws. For example: see the red box.
39. CAUTION: Don't damage the Li-ion battery or something bad will happen, such as gas leakage, electrolyte leakage, fire, and explosion. REF: https://doi.org/10.31224/osf.io/swcyg

40. Lift the Li-ion battery gently.
41. Pull out the flat cable gently and then remove the Li-ion battery completely.
42. Background: About the flat cable. Generally speaking, the red thick line is the "+" power line; the black thick line is the "-" power line; other thin lines are signal lines.
43. CAUTION: Don't damage the Li-ion battery or something bad will happen, such as gas leakage, electrolyte leakage, fire, and explosion. REF: https://doi.org/10.31224/osf.io/swcyg

44. Condition: The double-sided tape of the plastic part is degummed and has lost its stickiness. The plastic part clearly leaves the surface.
45. Remove the double-sided tape that has lost its stickiness.

46. Use new double-sided tape.
47. Paste the plastic part back to its original position.
48. Do the same on the other side if necessary.
49. Suggestion: Do the same on the other side even though the plastic part sticks right on the surface. Because the old double-sided tape might not provide sufficient stickiness.
50. Other methods: The epoxy AB glue can replace the double-sided tape.

51. Plug the cable into the new Li-ion battery gently and tightly.
52. To reassemble the laptop, follow steps 3~11 in reverse order. Some possible conditions and how to handle them will be described in the following steps.
53. NOTE: Make sure the cable is firmly inserted (the red box).
54. CAUTION: If the cable is not firmly inserted. Several worse conditions might happen. (1) Power failure (No electricity) and (2) Unstable connection cause an electric arc, fire, and explosion.
55. NOTE: Make sure the cable is securely fastened (red circles).
56. CAUTION: If the cable is not securely fastened. The cable might be squeezed by other parts, causing an unstable power supply and even safety issues (arc, fire, and explosion). REF: https://doi.org/10.31224/osf.io/swcyg

57. Condition: The stickiness of the old double-sided tape (black) is not sufficient to stick back the plastic sheet (silver).
58. Use new double-sided tape (white) to stick the plastic sheet and the old double-sided tape.
59. NOTE: The new double-sided tape should avoid the soundhole (red box).

60. Condition: The damaged plastic sheet (silver) is caused by the "destructive" teardown in step 9.

61. Condition: If the stickiness of the double-sided tape is not sufficient, causing a spacing.
62. Suggested method: Repeat steps 14 and 15.
63. Other methods: Use tape to fix the problem. In this case, the yellow tapes are used for the clear demonstration. Users can use other color tapes.

64. After replacing the battery, please check the appearance of the laptop.
65. Please turn on the laptop and unplug the AC power line to check the functionality of the battery.

66. This is an optional step. This step can be skipped when users don't want to know the battery status or don't have the software.
67. Check the "cycle times" by battery software.
68. Suggested software: (1) BatteryInfoView, (2) BatteryMon.
69. For example: BatteryInfoView shows that "Number of charge/discharge cycles" is 0 (red box), indicating that the laptop treats the battery as a new one.
