No. See my first post and some others. It suffices to disconnect the pad connector. Just be careful wihen lifting the motherboard. ;-)

Hi Strells, in the english or french version, it seems that it is always step 50 (two screws for battery) and 46 (“lower” screws for motherboard).

I did’nt. See my previous post. Just be careful wihen lifting the motherboard. ;-)

In order to not remove everything, I reduce the procedure in following only steps 1 to 18 (until trackpad cable is pushed away).

Then I removed the “low “ screws of step 46 in order to losen the fixation of “bottom” of the motherboard, as there is no room to remove the battery board and its ribbons).

Then I removed the two screws of the step 50 (battery board). To take off the glued battery, I used twine or thread (as Jeff indicated) but not acetone nor diluant in order to not spoil motherboard or another component).

Then I lifted very carefully the bottom of the motherboard both to push away the battery board and its ribbons and to reinsert the new battery board and ribbons.

Then I proceed backward to remount (step 50, step 46 then step 18 to 1).

Note: my “old” battery was so inflated that the two screws of the lower case near the trackpad were difficult to remove (sometimes, this leads to a malfunctioning…

Thank to Jeff for this overall procedure which helps me a lot.

Hi,

The type of the original battery is LiPo. In my reply of the 2019/03/17, I post a few links for batteries, the amazon link does not work anymore, but the alibaba link is ok.

You could also use this battery at aliexpress (same capacity, but smaller in size, and same thickness, so it should fit):

But you could also use a battery replacement for the samsung galaxy S4 as I noticed in the tutorial (could be found in amazon or elsewhere).

Cheers,

Godzil, you are right. Although I had no problem with the battery of galaxy S4 installed in my cybook for more than one year, I indeed recommand you to take a battery which has the same characteristics as the original battery.

The characteristic of the original battery is Lipo 1650mAh, 3.7V and dimensions are about 5x46x60mm.

(see http://www.bookeen.com/fr/supportfaq/sho...)

You can see such batteries for example here :

- http://www.cpkb.org/wiki/Samsung_EB-F1A2...

This one is 5.1 mm x 46.1 mm x 59.1 mm, so lightly more thick (0.1mm), it should fit well in the cybook.

- http://www.alibaba.com/product-detail/ul...

- http://www.amazon.com/35H00185-01M-1650m...

These two are 5x50x60mm but I think they should also fit well in the cybook.

I modified the tutorial to take into account your remarks. Thank you.

I think it is ok. All batteries for galaxy S4 do not show the mAh (I do not remember what was written one the one I have put in the cybook). But you can measure the battery, the dimensions I mentioned in the instructions are about 5 x 46 x 60mm. For the capacity, 2600 mAh it is better than the initial 1600 mAh (but voltage must be the same, or very near 3,7V).

I add a picture with the new Galaxy S4 battery in the step 4
