Thank you very much for such a detailed instruction! Had the very same problem with a bloated battery in Alienware 15 R3 (2017). The malfuctioning battery already cracked the base panel between the touchpad and the front edge, and lifted the base panel badly. Looked horrible. I was afraid to lock the laptop out of fear to damage the screen, and that sulfuric acid from the battery may leak and cause a wreck. Thanks to your instructions the complicated removal procedure passed out successfully, without damaging a laptop, just a few screw plastic bases cracked somewhere. I failed to unsrew those tiny screws for led panel connectors in the back corners, since all my screwdrivers turned out to be too big for it. But I managed somehow to proceed with battery removal without disconnecting the led connectors, just removed carefully those optic sticks. When I have reassembled the laptop back, everything worked fine. The base panel smoothed out, and even the cracks turned to be unnoticeable. Thank you!

This was very helpful. Ordered the battery as soon as I watched this video and replaced it without any issues. Went ahead and cleaned all the components and changed the thermal paste as well. Gracias!

42:38 THANK YOU. I spent hours trying to refit the battery connector to the motherboard. All the other videos I watched skipped over many steps or said “just reverse the steps”, while coyly ignoring all the important details. This video is excellent! Thanks again. Hopefully my laptop comes back to life when I charge up the new battery. 😊

Thank you! Great video and explanation. It certainly is a lot of work just to change the battery, but while I was in there I upgraded RAM, cleaned the fans and did the CPU and GPU re-pasting as well. My fans had a very slight different casing mechanism but nothing too complicated. For anyone who’s planning to do something similar, you might as well buy the thermal paste and thermal tape (just in case yours is worn) and do it all. Get extended life from your laptop

Hi mate, Absoulte champion, thank you! Just completed mine, following along with you step by step. I've never worked on ANY computer before and you empowered me to give it a try and it was a great sucess! All the best, from Melbourne Australia

I bought a replacement battery for my 4 year old Alienware laptop thinking replacing the old one would be like any other. Many thanks for your video, it was very helpful and allowed me to change mine with not a single spare screw left afterwards :)

This video is a life saver......step by step (giving me the chance to pause and follow along)....saved myself a pretty penny, just ordered the battery and a precision screwdriver set and was able to swap the swelling battery in about an hour....great video

Thank you. I found your video very helpful in changing my Alienware m15 R3 battery! 2018 laptop. The original Battery was bulging bad in 2023-2024. I bought a 99 watt/hr for $40 on Amazon. 9NJM1 is the battery model.

Thanks for the vid. Wouldn’t have had the confidence to do it alone. Awesome. New battery works great.

Thank you! This gives me enough courage to try to replace my fan myself

It's absolutely crazy that you need to do all of that to just replace a battery.

Thanks! That was very helpful. I snapped one side of the keyboard connector holder arm, I fixed it in place with some gorilla tap, works like a charm.

thanks for the video had to change the battery on mine since its 7 yr old now

Thank you so much for this video, you really helped me out with replacing my battery, the whole thing was starting to look like a very swole piñata

I would have given up without your video. Thank you for posting!

Thank you! You’re a life saver. A computer saver too- my old battery had started swelling.

Thank You! Your video was SO much easier than trying to follow the 140 page Dell 15 R3 maintenance manual!!!

Awesome, this is the first time I opened my laptop, and I found the battery curved. Now I'm going to order a new one, you really helped me to protect my pocket.

Nice video... I used it to replace my battery in my Alienware 15 R3 system... great detail. I would recommend special care on pulling the battery wires and the lighting wires... those tend to be very delicate. Again, thank you for an excellent video and education on how to replace this battery.

Very much thank you for your video saved 100 bucks for replacing the battery.. Godbless you sir

Thank you, just did a battery swap and now I'm back to a few hours of life vs less than an hour. Gifting it to a relative so it can have a second life.

Thank You. Your video was very helpful for me and well explained. I will treat my New Battery much better in the future. 👏👏👍

Very good instructions easy to follow thanks for this!

This is amazing! Thanks for doing this!

Very clear n informative video keep it up

This helped me a great deal. Thank you!!

Thank you, very helpful mate.

Thanks! This helped me a lot!

Great video! Thank you so much!

Thanks, i'm going to revise it myself in order to resell it.

Thanks for making this. Very useful. Did you use only one size of screwdriver for the battery removal?

Thank you very much!! Very helpful!

Great video. So hard to keep track of all the screws. Tks!!!

Really helpful video! Is there anyway you can link the tools and products used?

Very nice and detailed video

Great video! Thank you 🙏

Thanks for the guide, I have the same laptop and it gets hot! What temps do you get now? I will have to go through the same process.

which screwdriver to use to remove heatsink screws. my current one doesnt have a tip that works.

And ppl complain about working on their cars....lol. I need to replace my battery and was going to have a pro do it. I might try it myself as it's more just time consuming vs difficult. Thank you for the video!

I forgot what cable I have to plug in to get the backlights and keyboard lights working again

if i remove the battery my computer could still be turned on?

Just a quick question. If my computer is plugged in , an the alien head where you power it on just lights up on n off dose that mean I need a new battery ?

Iam having temperature issues with my 15 R3 can you make a video on cleaning the fans please

I just finished doing the battery exchange and your video was very detailed and perfect. I felt like I was a heart surgeon with a doctor guiding me every step. Thanks for the video, you saved me time and money! Axe

hmm, now the audio dont works anymore. do you know which cable was the audio cable?

What are compatible alternative interal 1TB SSD brands for this Alienware? Thanks

What size screwdriver head do you use for these screws?

THANK YOU MYSTICAL WIZARD

Hey can you recommend a good place to get the replacement battery please? I pulled out mine today using your video. It was super swollen. The laptop had given me a battery permanent failure notice

My touchpad no longer works after opening the lapto. no damage to the port nothing. really buffled what to do.

Hello sir , Can u pls provide details of thermal paste and will it be Available in e-commerce websites in online to purchase? After applying the heating issues are resolved completely right ? Actually I’m facing same problem with heat issues with my laptop

Thank you!

thank you!

So when there’s no power it’s a must to replace battery? Power cord is useless without a hood battery in this laptop? If so this sucks major. So yea Gratitude for your great help

It’s ridiculous it’s this much work to get to the thermal paste. I hope future models it will be visible once your remove the case.

looks painful - I hope to not have to do this anytime soon!

91C is not “very very hot”…

Axelander

Are you flipping kidding me? What brain-dead engineer buried the battery so deep in this thing that takes an hour to replace? Unbelievable.
