Question

Too cold for my hardware?

by Radnm / November 19, 2011 7:54 PM PST

I have a Acer Aspire laptop, I forget which specific model, but I have a Nvidia GeForce GT 420M graphic card.

Ever since the nights started getting colder (and it can get down to 0-5 degrees Celsius at night here), the screen on my laptop would be "missing" the lower half for about a minute or so, but once the display starts working properly, there's no issue anymore, I mean, even if I reboot or anything, I don't get display issues.

The problem only appears on the first boot of the day, after a cold night. I also tried to put the laptop next to a heater for a minute a few days ago, and then it booted up with no display issues at all.

So I wonder, is that normal behavior that will not cause long-term problems, or should I have a chat with the guys for some hardware support?

Clarification Request
Extremes

You need to check the "operating specs" of the laptop. More importantly it maybe called the environmental range as it were. If its too cold, then that's not the fault of the PC. You need to get into the operating range it was intended to be used in. Operation under extreme factors can cause "creep" of components and/or cabling, they literally pull away from their seated position, once they warm-up they return. However, in some cases, it maybe so bad, contact is lost or possible damage if shewed. Take my advise, place the laptop as you already know by a heat source to warm it up or allow it to sit protected. If this is a laptop you leave in the car/truck, then use a rigid case to protect it, like a camera one or similar. Even if close to the operating range, the overall "life cycle" of the laptop is reduced.

Re: temperature

http://www.altadox.com/lcd/knowledge/lcd_temperature_ranges.htm (as an example) shows that LCD's do have a temperature range in which they should function.

So better contact Acer customer support and ask the temperature range they guarantee for the screen (and the associated electronics) in this specific model (if it can't be found in the user manual). If the range with you is smaller (especially on the lower side) it's a warranty issue (that's what 'guaranteed' implies).

Seems a knock-out criterion for your next laptop!
