Introduction

If your Dell XPS 15 9550 laptop will not power on without being plugged in or not hold a charge for an extended period of time, you may need to replace your battery.

Tools

Parts

Step 1

Turn the laptop upside down.
Make sure the laptop is turned off.
Use a T5 Torx Screwdriver to remove the ten 3 mm long screws from the perimeter of the back of the laptop.

Step 2

Open up the information panel door (on the middle of the back side).
While holding the door open, use a Phillips #00 Screwdriver to remove the two 10 mm long screws.

use a J1, fits a lot better. no risk of rounding

Size is Philips #0 not #00

Step 3

Carefully lift the 2 corners of the back panel close to the hinge upwards, to release the whole panel.
Do not force the panel off. If it does not come off easily, try to use a plastic spudger where it is stuck.

Dégouté d'avoir suivi cette étape à la lettre ?

N'ouvrez SURTOUT PAS le panneau par les deux coins arrières du côté de la charnière !!!

Et N'utiliser SURTOUT PAS une spatule en plastique pour l'ouvrir si le panneau ne se détache pas facilement !!!

Le panneau est fait pour s'ouvrir par les coins avant!!! A l'arrière des picots servent justement à l'empêcher de s'ouvrir !!!

Le résultat si vous utiliser uns spatule à l'arrière… c'est que ces picots cassent… ?

IL FAUT DONC OUVRIR LE PANNEAU PAR L'AVANT !! Et il est juste posé donc inutile d'utiliser une spatule…

Voilà voilà je suis dégoûté d'avoir fait cette connerie alors qu'en cliquant sur un autre tuto (lien juste en dessous sur Google) ils le disent…

J'espère qu'après mon commentaire l'auteur de ce tuto fera la modif…

Sur ce… merci pour le tuto…

Step 4

Use a Philips #00 Screwdriver to remove the seven 3 mm long screws from the perimeter of the battery.
Each screw is labeled "M2X4" with an arrow pointing to the screw.

Everything went great to this point … but the #00 Philips screws securing the battery will not move! The seven screws holding the battery are torqued down so crazy tight the #00 Phillips screwdriver is stripping the heads of the screws. I stopped trying before damaging the screw heads any further. A quick Google search indicates this is not an uncommon problem, but there are no clear solutions (other than sending the computer to Dell). Does anyone know how to get these screws to move without heavily damaging them?

iFixit has a guide with several tips on removing stripped screws here. Just make sure to take care as you work through the guide and stop and move on to the next method immediately once you notice the current one isn’t working so you don’t further strip the screws. One last tip: instead of using a rotary tool with a cutting wheel like in the last few steps of the guide, you can use a flat head that is oversized for the stripped screw as a small chisel to slowly and carefully carve out a notch in the screw head. This works just like the cutting wheel (albeit slowly) to create a notch you can use to remove the screws. Damaging the screws isn’t ideal, but replacement screws are fairly inexpensive and widely available. Good Luck!

Tarun Thiruma - 30/09/20

Please note: for those with a 56 Wh battery, there are four 3 mm long screws holding the battery.

Step 5

Gently lift up on the backside of the battery.

Step 6

Firmly grasp the black connector on both sides.
Carefully pull the connector towards the battery, to release the connector and the battery from the laptop.

Conclusion

To reassemble your device, follow these instructions in reverse order.

… Mais avec un prix imbattable, la batterie made in RPC arrive avec un connecteur très très épais !

Finalement il m’a fallu me résigner à forcer très durement l’intromission avec deux paires de pinces !!!

Barbare mais efficace ! C’est le contraire de out ce que j’ai enseigné pendant des années : “le connecteur approprié doit toujours s’insérer en douceur” Ben là … NON !

English translation:

… But with an unbeatable price, the battery made in RPC comes with a very very thick connector!

Finally, I had to resign myself to forcing the intromission very hard with two pairs of pliers !!!

Barbarian but effective! It’s the opposite of what I’ve taught for years: “the right connector should always fit smoothly” Well there… NO!

Hallo, ich habe alles nach Anleitung durchgeführt, allerdings kommt eine Fehlermeldung, dass der Akku nicht akzeptiert wird, da kein Original Ersatzteil.

Den Haken im Bios bei Adapter Warnings habe ich bereits entfernt. Hat jemand eine Idee?

Thomas Haupenthal -

Hallo Thomas, wo kommt denn die Fehlermeldung? Im BIOS? In deinem Betriebssystem? In einem bestimmten Programm? Was läuft denn auf deinem Dell?

Fabian Neidhardt -

Geht mir auch so: Fehlermeldung im BIOS auf Windows 10. Ob ein BIOS-Update das Problem lösen würde weiß ich nicht, weil ich dafür 10% Akkuladestand bräuchte.

Fuchs -

Dell hat eine eigene Supportseite für Akkus, unter anderem mit der Info, wie du das BIOS-Update unter 10% erzwingen kannst. Und in diesem Thread heißt es, dass es Akkus gibt, die eigentlich für einen anderen Dell sind und deshalb passen, sich aber nicht laden lassen, weil Dell diese nicht als Original anerkennt.

Fabian Neidhardt -

Excellent Guide. Just a note, the screwdriver required should be a Philips P1, not the P00. This applies for both the bottom two screws under the flap and the screws securing the battery inside.

Thank you,
Matt

Is this battery a little thicker then the original? When I replace the case the track pad doesn't have quite enough room to travel anymore so it's hard to click and I can't click and drag.

Matthew Davidson -

Having the same issue. Atm I am considering to send the battery back! Any progress on your half on this?

Akra -

also had the same issue. i used some of the foam that the battery came in to shim around the trackpad. that seemed to give it enough room to click. so far so good.

Easy installation of the new battery but it is not charging. I'm getting message at start up that it's not a Dell battery. I have done some research but can't figure out a way to get the system to recognize and accept the battery and charge it.

daviddawson747 -

Instructions were clear and concise. No problems with the battery supplied. There was a screw holding the battery that was damaged. Managed to get that out and the new battery slipped in place. Took a bit longer than the 10minutes but that's because of me being a bit more careful not wanting to drop the little screws into the laptop.
