Enable secure boot, maybe its windows problem, if you dont have EFI folder, maybe the bios is searching for i thats why F2 and F12 is appeared. Should check it.

Hello people, im Dell 5448 user, upgraded RAM to 16GB and 512GB SSD(Samsung 850 PRO), since the processor is Core i3, i think i can beat macbook pro 2012 performance as im installing mac osx on it.

For the wifi problem faced by 5447 and 5447 user, you can fix it by changing the WiFi card, like me, i changed to broadcom mac compitable card, and it fixed the issue.

I can say that this model is good. It has same keyboard as 7447 which has backlit keyboard, i changed it which price RM85 only, bought from Dell China. I also changed the screen to 1080p (which dell 7447 has the version too), i can conclude that i dont regret buying this laptop. recommended dell as its warranty can be extended.

But the issue for now is,  The battery life is not good since it has small battery, thats why. I'm planning to get a bigger battery but its not available for this model.

u install osx on your dell?

Yes, bought this for my hackintosh project. So far, i found that this model is the smoothest installation process i did.

does it works as good as a mac or there some problems here and there?

Errr....what you mean by ddr4 bro?

if you mean the graphic, it pack with GTX 960M 4GB GDDR5.
if you mean the ram, it only supports DDR3 ram.

The battery life never perform what the advertisement says. 8-10 hours? no.
6.xx hours, if i turned on the battery saving mode.
4.xx hours, if i no turned on.

But mine plug in with a m2 ssd 1280.
The battery life still 4.xx hours if no battery saving mode.

fyi,
my spec is i7 but no 4k touch screen.

You mean your M2 SSD costs RM 1280? That is really expensive.

m2 is slightly more expensive than normal ssd my 250gb already RM480

RM480 from Dell?

i got the intel 540s SSD  from 3rd party with 5 years warranty.

You dont need to buy from DELL. you can buy it outside.

But won't  removing the back cover and placing it in your laptop void the warranty?

Nope, if it requires to remove area with a seal , you cant. but on the dell 7559 it just 4 screw and the back cover is off.

btw you are not replacing. There an empty slot just for m2 next to the msata hard drive

I thought is only 1 screw then can pull the back cover out

1 screw ma good for him

Basicall you had someone instal it for you, correct?

I have always had the understanding that if you add internal parts, you are voiding the warranty. Guess I will check with Dell before purchasing it.
