I mention this because of the iDP 768p machines like my old E7440 (gov't special, mic only/no cam with iDP LCD, 768p LCD).

There's a reason you see so many people sell "cracked LCD" 7480/90 machines. If the LCD is enough to make people sell the laptops, that's not a good sign for repairability!!!

| These use a less common “SLP” (Super Low Power) panel, as well as the 7490. In addition to that, Dell also uses a different iDP cable on “HD” (768p) machines, and a different cable on the FHD units (usually BOE or LG IPS) — it’s not different in name only, like the 768p 7440 I had in production before time got to it (as well as it's nearly 10 year old battery). What you need will vary based on the resolution of the existing LCD, or if you have a 768p unit and want to ditch the 768p LCD for FHD IPS, you will need to replace the LCD cable, and LCD - buy a used assembly/donor with the part for this. | |

| + | These use a less common “SLP” (Super Low Power) panel, as well as the 7490. In addition to that, Dell also uses a different iDP cable on “HD” (768p) machines, and a different cable on the FHD units (usually BOE or LG IPS) — it’s not different in name only, like the 768p 7440 I had in production before time got to it (as well as it's nearly 10 year old battery). What you need will vary based on the resolution of the existing LCD, or if you have a 768p unit and want to ditch the 768p LCD for FHD IPS, you will need to replace the LCD cable, and LCD - buy a used assembly/donor with the part for this. |
| - | First thing to do is figure out the resolution, as you need to match that up to your old panel. Once you know which one you need, you’ll need to locate a panel from a reliable supplier. ***BE WARNED screens can sometimes be expensive for these due to the SLP LCD so be prepared to negotiate or get priced out of the repair due to losing economics. This is not unheard of for the 7480/7490.*** You can find part numbers [link|https://www.parts-people.com/index.php?action=category&id=140&subid=971&refine=lcd+screen|here], as well as the part.[br] |
