    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!

… 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 !
