Happy Holidays. Got a bit of a problem with the old laptop here.
Basically, the screen won't turn on if the temperature inside the room is too warm. That goes for both regular boots, and returning from sleep. Also, if the screen goes off due to the 15 minute power saver option (in a warm room), it will not turn back on. I must stress, this ONLY happens if the heat is on inside the room I am using the laptop in. If I keep the laptop in a cool room, this problem does not occur. If I have the laptop completely off for a full day, and try to turn it on in a heated room, the screen won't go on.
I have Core Temp on the PC, and the laptop seems to be running at an acceptable temperature. I also cleaned out the fan/heat sink area. But it doesn't seem like that would be the main issue, as the laptop apparently overheats even before it's on.
Conventional wisdom says get a new laptop, or keep the heat off.. But if this problem sounds like something that can be remedied with a part replacement, I'd prefer to do that. Perhaps the video card needs to be replaced?
By the way, this is a Lenovo laptop from about 9 years ago.
Thank you very much for your input,
