Hello,
A couple of weeks after a mechanic from Dell came to fix some other problems, including the motherboard's built in graphics card, the power cable and the LCD screen, the laptop started to randomly go into standby mode. Gently wiggling the screen usually made it go back to normal, indicating it looks like a problem with the power cable again. Now I'm not sure whether it's hardware, but seeming as the laptop is not getting too hot and the Dell Diagnostics report no problems, I strongly believe it is. The temperature of the laptop is 55-60 C tops, for the graphics card, lower for everything else.
Seeming as everything has been replaced several months before the warranty expired, I can not contact Dell via mail again. I don't know exactly what was in the warranty, as I cannot find it anywhere anymore, but I reckon a defective replaced hardware part has at least 1 year warranty despite the general warranty. If so, how can I arrange for analyses and replacement, seeing as it is likely accidentally gone wrong during the mechanic's last visit?
Many thanks in advance, I really enjoy the laptop, and I would love to continue doing so for a couple of years if possible!
