Gateway Laptop Monitor Overheats

gateway laptop monitor overheats unless i just use the external monitor--i wonder if i should just take it apart and recycle it for parts

i did install the OS somehow i guess by unplugging the power cord and it ran on battery with external monitor and laptop screen went blank and then i got in safe mode --before that it asked which screen to use and i choose external but now i can only get in safe mode

is there a key to hit to change it or or bios

the screen gets so hot and the corner is blotched i wonder if it will fizzle in flame

maybe this thing is too unsafe to deal with especially a novice if i give it away

 

I would recommend on cleaning it out first be for any of that.

Buy a can of air duster and clean out your laptop.Make sure your laptop is powered off and battery is taken out.

See if that helps there should be no other reason for a laptop monitor to over heat.

But it could all so be your settings resolution as well causing it to over heat.

 

For sure, vents covered and fans caked with dust could sure cause heat issues. If this is a CCFL/Inverter backlit monitor, they do get pretty warm compared to LED backlit monitors - especially if the brightness is turned all the way up. But there could be a component failing too where its resistance has dropped (near short). And when resistance drops with the voltage remaining the same, current goes up (Ohm's Law) and so does heat.

"So hot" and "fizzle in flame" are really relative terms that may or may not mean anything, depending on how hot, as measured in actual degrees, that is. If so hot due to a failing component, I would expect there to be a shortened battery run time too. But then batteries degrade over time naturally so that may also be hard to determine.

Are the fans spinning?

 

can of air-where do i spray? through the air vent? it overheats in one corner and the screen is smeared as if its going out-its scary

but when the external monitor is working it cools off and goes blank

in bios do i turn off monitor for only external?or is it a key?

thanks

 

Typically, you can cycle through "notebook monitor, external monitor, or both" by using a Fn + F-key combination. There is no industry standard so you will just need to look at your keys for the appropriate icons, or look in your manual. On my Toshiba, it is Fn + F-5.

FOUND THAT BUT STILL WONT WORK MAYBE ILL TRY EXTERNAL KEYBOARD LATER

 

the three discs i made off the hidden operating system are just used in event i need a whole new harddrive?so when i did a new install all the drivers were on the gateway disc?so i should have all the drivers on it now?

 

External keyboard? What do you expect that will solve?

You don't typically have to do anything as far as Fn keys when using an external keyboard. Just plug it in and go.

Yes, the drivers should be on your disks or you should be able to download them from the notebook's website.

 

Hmm did not realize some laptops came with that type of monitor.I am really not laptop savy.

 

It was the standard on older LCD displays. LED backlighting is a recent development.

 

^^^ What he said.

"All" older LCD monitors used CCFL (cold cathode fluorescent lamp) and inverters for backlighting. Most, if not all today use LED backlighting because it (now anyway) is cheaper, more efficient and more reliable. They are both LCD - it is just about the backlighting.

We never did get the model number of this Gateway so we don't know if it is using CCFL/inverter or LEDs for backlighting. That's why I said above, "If" this is a CCFL/Inverter backlit monitor... .

 

why cant they make a laptop thats easy to change heat sink paste?--i just gave it away--wonder if thyll recycle or attempt to use canned air

 

Several reasons. For one, there is no form factor standard for notebooks like there is the ATX Form Factor standard for PCs. There is also a huge consumer demand for thinner and lighter. Those two reasons mean notebooks are very proprietary and there is no easy way to simply remove a side panel and climb in.

Also, contrary to what many seem to think, you should never need to change the TIM (thermal interface material). Remember, it's only purpose is to fill the microscopic pits and valleys in the mating surfaces pushing out any insulating air. Even if it dries out, the solid materials left behind are still occupying the space preventing air from getting in. It does not wear out or need replacing unless the cured bond between the mating surfaces is broken. And that should not happen unless you remove the heatsink, and there's little reason to ever do that. TIM will easily last 10, 15 years or longer, if the bond is not broken.

Yes, it does lose a few degrees efficiency over many years, but if you really need those 3 - 5°C to keep the system stable and running at full speed, you have other problems, like a blanket of heat trapping dust stuffed inside, or a fan that is worn and slowing down.

Finally, because most users are not aware of ESD or how to prevent, it is not uncommon for users to destroy their CPUs, RAM and other ESD sensitive devices when digging around inside a computer. Some users even forget, or just don't realize they need to remove all power before digging in. That means unplugging PCs and notebooks from the wall and with notebooks, removing the batteries.

I wish there was an ATX type form factor standard for notebooks. If there was, then there would be a thriving custom build industry for notebooks like there is with PCs and I would be building notebooks as well as PCs.

In any case, that would have nothing to do with your notebook monitor getting hot.
