Dell 7490 Battery Replacement

[@j0mbie]

Great video. Some tips for anyone that might need them: The case screws (unlike the battery screws) don't remove fully from the case, they just "unlock" from the rest of the laptop, so they don't get lost. Once those spin freely, it's unlocked, but you might notice a couple didn't unlock while prying up the case -- just unscrew a little further and you're fine. When removing the case, you don't need a spudger -- you can just pull up on the case from one of the loose screws using pliers to get a credit card wedged in there, then slide it along the edge and it should pop up each "snap" connector. Where the cable attaches to the battery, when removing, make sure you grab all the wires under the tape firmly at once while removing to prevent pulling a wire out of the harness. Just very firmly squeeze the tape (front and back, not side and side) while removing. The tape might pull back a little but that's OK, just push it back down the best you can after reattaching to the new battery. If your new battery has tabs on the bottom (not all do) you need to "lever" it in, bottom first, or else the bottom doesn't sit down all the way. This can lead to the case appearing to bulge afterwards. If in doubt, "lever" it in anyways, as it won't hurt if you don't have the tabs. Mine didn't recognize the battery on my first attempt. It turns out that where the battery cable attaches to the motherboard, needed a firm pressure to fully seat into place. It looked fine at first glance, but each side of that part visibly slightly pops into place when you give it more pressure. If you have a flat, non-conductive, non-static-generating surface to place the laptop on, you can test it before placing the case back on (but after attaching the battery screws). A good surface would be the case itself, flipped around so that the inside is facing your desk. If you're nervous about this, just attach the case, because at worst you just need to open it up again. If your case doesn't close all the way afterwards, make sure all the "snaps" are connected -- just go around the edges of the case giving it a good squeeze one section at a time. Sometimes you can feel it pop into place, sometimes it just seems to move.

How's the battery life?

[@norbertolevin1344]

Thanks Frank, your video was perfect for me! not being a computer techie I was able to replace this notebook battery and save time and money taking it to a Dell service shop. Thanks a lot.

[@BryanSeigneur0]

1:00 Pro tip: you don't have to pry off the bottom lid of the laptop if your old battery is so puffy that it just pops it up as you unscrew the screws! That was my case! 🤣

[@helenpennock2012]

Thanks. These were very clear instructions. I'm going to give it a try at the weekend. Quality content

[@bjapayot3]

how did it go?

[@helenpennock2012]

@@bjapayot3 very good, the instructions were great and the procedure was successful.

[@warrengrosch1603]

Thanks Mate. Replaced and good to go. What I discovered though is, in removing the casing it's simpler starting from the back and then when replacing, slide in from the front.

[@JohnPaulsEuropa]

Thanks...was spot on for this unit.

[@scottcarey5573]

Thanks. Exactly what I was looking for!

[@telocities]

I wish they would make the battery pop out, so nice to be able to carry a spare battery and switch if needed.

[@anna-kayehood6696]

i have a small issue i installed the battery and the computer is charging okay but a part at the front is bulging and cant close properly. I've checked if all the screws were in properly but I cant figure why it's bulging. I need some advice

[@michaelbuono9826]

Good tip for disposal of old one?

[@Peter_Jenner]

"Sometimes there's a screw in here...". No there isn't - that's the hole for the centre case screw.

[@haganbush1480]

Thank you! Great job explaining. Obviously a very good teacher!

[@ChristianMercadoAcevedo]

Thanks Frank. Great content.

[@WIDERisBETTER]

This is awesome thank ypu for showing this. I have 7490 and it had the smaller 3 cell battery. I accidentally ordered the 4 cell without taking it apart to see I actually had a 3 cell in there. The 4 cell fors and works, so hey ill enjoy longer battery life!

[@rcbackup2598]

Thank you !

[@Zneiero]

Even with this 'problem', its still faster than a Stinkpad. Good machine. Don't listen to the techs who say its trash. These are rare defects that are not widespread.

[@rafaymago1]

I ve seen your videos, I have a surface 2 pro and the battery is done.

[@yasinsahin9291]

Awesome job, thanks for the clear explanation.

[@majidali6979]

Sir how much battery gives us on screen timing not original battery please sir guide me please🙏

[@user-sp9sk8lh6j]

i dont understand why all of this batteries come without cable. I bought on Ebay Dell e7390 without battery, and in fact it was very hard to find this cable itself, only 1 seller on aliexpress have it. My previous was Dell e6430 and its battery is magically good, after 8 years i have 54% left and it holds good 1.20-1.50 hours, hope my new chinese battery dont die in 3-6 monthes

[@Upgradetech]

Another reason Dell can make more money

[@6229013]

Thank you 👍

[@ryancraig2795]

Just got a new 4 cell to replace the original 3 cell in my 7490. I checked that it would fit before ordering. Your video was helpful, thanks! Looks like I now have something like 8 or 9 hours battery life instead of 1 or so.

[@IdkwhatdoIwrite]

Mine says battery not detected after replacement.

@@Upgradetech Can I upgrade me 42WH one to the bigger battery? I took the bottom case off and there is room for a larger battery in the chassis

[@bmag54palla]

Hi, where can I buy the cable? Batteries come without cable, eventually can you give code number

[@Upgradetech]

eBay and Amazon do a picture search using Google chrome

[@kashyap1991]

using the excat same model of dell facing some battery issues works all great from 100% to 40% but after 40% marking a sudden drop to 6% within seconds may i know the reason as the batttery health report generate the battery health is still showing good ?

[@Upgradetech]

The battery would need to be recognition or replace.

[@kashyap1991]

@@Upgradetech ok but I have 02 laptops of same series Latitude 7490 both are having same issues i think somewhere its not battery fault

suena a otro problema. Cuando la batería ya no sirve en efecto sale un mensaje al encender el equipo, pero el q describes suena diferente, puedes escribirlo literal tal cual te aparece?
