Laptop on it's side?

I am using my laptop with an external monitor & keyboard. The screen is
folded down all the time. Is it okay to leave it in a vertical position
sitting on it's edge all the time? If so, would the CD still work okay?

Thanks in advance... Bob

Depends on the temperature produced by Cpu& Co if it stays under 55° then
you can leave the display. Otherwise it could fade andd the colours would be
somewhat blurry- after a while. If you have a slot-in CD- then maybe
vertical is not so good, All the others are fixed in the spindel which means
that is does not have any much effet..

Are you saying that the screen should not be closed if the computer temp is
below 55? Hoe would you take it's temperature? BTW I have a Compaq
R3120US.

erh, vice versa!
If it is below 55° then you can leave it closed. If t heats up, then open it
a bit to prevent the display from burning. In older days you could see a
display brighten up if it was closed while working or gaming. the colors
were gone for a while. When it got back to normal temperature then it as
well got back to normal. My dell has a sensor. I think your Laptop should as
well have one, if the fan isn't blowing all the time. Because then it is
temp sensitive controlled. I know only of one, meant for my 'Lap' called
i8kfangui- download at www.diefer.de. It should work with yours hopefully.
Normally if not using CPU intense calculations it should stay belowsay 60°-
which is as well acceptable. But the lesser it goes up- the longer youre
investition will last!
I.e. the MBTF (mena lifetime of a HDD) is shorten tremendously if the hard
disk heats up over 50°!! (Celsius I am talking- not fahrenheit)
Most laptops will become hotter than specified. They are cheating us..

I spoke with Compaq and they said that it was okay to keep it closed all the
time but they didn't recommend having the computer vertical. They didn't
elaborate as to why.

okay,
I do use mine with a dockingstation and a secondary monitor besides my
integrated one. i don't trust this speech- as I said before the HDD is
definitely suffering from overheating..
It is up to you- thx for the info

All the Acers and Toshibas I have ever owned have had a switch on the hinge to
detect lid closure, and this kills the drive to the internal screen.

This is correct, most have it beneath the hinge, some inside the closure
hinge. But I was nt concerned of the light bulb, but of the heat emmitted by
CPU GPU DIMM and HDD!
As I said. Infos are provided, anyone can chosse by himself..

Having the computer vertical will change the airflow and cooling
patterns (many laptops use "heat pipe" water cooling). Also, some
CD/DVD drives won't work if they are not horizontal. Those are the only
things that I can think of.

Thanks, I'll play it safe and keep it flat.

Sorry Laptops and water cooling? The only one I know was sold in Japan..

A heat pipe does in fact use water in it's cooling function...

Water is at a reduced pressure inside the pipe, it boils from the heat at
the cpu, and condenses at the cool end, thus moving the heat away from the
cpu to a larger cooling surface someplace else.

I should think that if you have the laptop in such a position that the water
is not sitting on the CPU (there is space in the heatpipe for the water to
condense... i.e. it's not completely filled), then you'd get some serious
heat build-up on your CPU in a hurry.

You know these Notebook stands? they can have an up to 75° angle. Dell as
well sells them for their notebooks. As an official accessory. I couldn't
figure any heat difference when working at the stand or normally on the
desk. So it seems as if not all vendors are using this technique or dou know
something more to tell?

thx

I really should have said "liquid" rather than "water", but it's a "heat
pipe", which transfers heat from a CPU to a heat exchanger (fan) using
liquid filled tubes. There is no pump, it's a passive device.

For example:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=31534&item=5131919279
(not a good picture, but you get the idea).

These are actually very common in late model laptops.
