Hi Mickey,
You should visit Redington Kenya Limited, 1st Floor, Westlands Square Building, Near Uchumi Super Market, Westlands Roundabout.
I believe they are authorized Dell dealers in Kenya. I went to them a while back when I needed a screen replacement for a HP laptop and since they are also authorized HP dealers, they had to order for the screen of that specific laptop since they didn't have one in stock, the only downside to this is that I had to wait for almost a month to get the screen imported and fixed on the laptop.
