    To whom it may concern
    I have a dell studio 1558. The problem I have is the laptop overheats and shuts down after 40 minutes. I took the laptop apart and cleaned the fan (Fan is working fine, no dust now). The weird part is that right where the memory is the laptop is the hottest so I’m wondering if the memory is faulty. On the other hand the mainboard was replaced 3 months ago so I’m wondering if whoever repaired the laptop before forgot to apply thermal compound to the cpu before assembling the heatsink.

    My question before I replace anything is the problem AMD architecture or just a heating fault with the board itself or both.

    If I’m writing in ignorence the I apologize.

    I was wondering if there is a way to test for memory, cpu or a fan/heatsink issue with this dell model.

    thanks

    • Patrick,

      First i would suggest loading a program called i8k fan gui, http://www.diefer.de/i8kfan/ . This program will help you monitor the temperatures of the CPU and the GPU and manually control the fans. Monitor them closely and try to find out the temps when the system shuts down.

      When the motherboard was replaced, was it replaced with an identical as the original? the 1558 had 2 different motherboards, one has an ATI GPU, the other has an Intel GPU, and they both use different heat sinks that aren’t interchangeable. If the wrong heat sink was used it will cause the laptop to overheat.

      Just so you know, I’ve never seen memory cause a laptop to shut down due to overheating. That being said, your problem will probably be with the CPU, GPU, or Heat Sink. I would start with the heat sink (the cheapest and most cost effective) and reapply thermal compound or pads and make sure it securely tightened down to the motherboard.

      If that doesn’t fix the problem, it is likely to be the GPU. Although I’ve seen CPUs cause this problem, the GPU is more common, unfortunately it is a part of the motherboard. Was the motherboard replaced with a new, used, or refurbished motherboard? If it was with a new, i would suggest checking the CPU next. With a used or refurbished, it could still be the GPU or motherboard.

      I hope this helps. If you are still having problems, feel free to call me @ 866-816-5254 and i will be happy to try and help further.

      Roscoe
