Can the CPU be removed from motherboard and upgraded to an i5 or so?
it’s seem the CPU can not remove, it is soldered on the motherboard.
could you put a dual band wireless card in this? if so what kind?
Hi
I’m wondering how I can reseat the keyboard ribbon cable and where exactly it is and can be accessed easily (hopefully). My internal keyboard stopped working but the USB external KB I have does work. Also strangely enough when the bottom is off the keyboard works +/- ok.

Is it possible to add any more than the included 4gb of RAM?
yes! you can replace it by 8GB PC3L-12800S
I’m looking at a couple of options from Hynix and Samsung but neither one is showing the ‘S’ at the end of the number, but are just listed as 8GB PC3L-12800.
Also planning on swapping the drive to the largest hybrid I can get, which I think will probably have 32gb ssd on a 1tb 7mm drive. Any suggestions outside of these two which will bring meaningful improvements?
Hi – I’m wondering how complicated it would be to replace just the plastic display cover which is developing hairline cracks; the display itself works fine. Dell is offering to replace that part with an onsite tech, but I’m wondering if it’s an involved job that could screw things up in the machine, which otherwise works ok.
I want to replace the “stock” Wifi/Bluetooth card with a “better one” – what Intel card can be a replacement ? Most I see have two screw holes and the in place card has only one mounting screw.
The intel card you want is a Intel 7260NGW it can be found on amazon AT THIS LINK: http://www.amazon.com/7260NGW-Intel®-Wireless-AC-802-11ac-Bluetooth/dp/B00GUNZUG0/ref=sr_1_1?ie=UTF8&qid=1427632873&sr=8-1&keywords=7260NGW+Intel®+Dual+Band+Wireless-AC+7260+802.11ac%2C+Dual+Band%2C+2×2+Wi-Fi+%2B+Bluetooth+4.0
The max theoretical speed is 866.7 Mbps it works great

So I just replaced the power adapter cable in my Inspiron 11 3147 because the battery was not charging. That of course entails taking the motherboard out. When I got everything put back together it started charging just fine. I very quickly discovered that there was now a problem with the Bluetooth though. The mouse I’ve been using for ages no longer worked. The computer showed as being paired. I checked the mouse batteries. I removed the mouse and tried to re-add it. Doesn’t find it. I took this mouse and was actually able to pair it with my iPad Pro and use it so that rules out the mouse. Is there a particular cable I may have not gotten attached all the way or something? Everything else on it seems to work normally.
I just want to say thank you.
this guide helped me to replace the charging port on this laptop!
thank you VERY MUCH.
