  2. 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.

    Best

  3. 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?

  4. 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.

  5. 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.

  7. I need to make sure the monitor display connection is tightly connected, since I’ve got a vertical line appearing on my screen. I’ve successfully switched out the memory & HDD in the past but can’t locate the display cable connection. Where is it – help please???

  8. Any recommendation for a replacement SSD, i was looking at the
    Crucial MX300 525GB SATA 2.5″ 7mm (with 9.5mm adapter) Internal SSD
    CT9016090
    525GB 2.5-inch internal SSD • SATA 6.0Gb/s • 530 MB/s Read, 510 MB/s Write
