i've noticed that my laptop has been really hot since i switched to linux. I think it can burn my skin if i put it on my lap without something in between. it's that hot.. anyway, do you think it can cause data on cdrom to corrupt? I've been experiencing alot of error reading data on cd that worked a few days ago. I usually put cdrom in case and don't think i store them near harmfull stuff.... (i don't think so......) error is always same. input/output error. absolutely no visible scar on cd. Of course there may be alot of possible reasons, but my cd gets REALLY hot in a min after I put it in cdrom. It gets so hot, i usually cool off after I take it out. Could this cause data to corrupt? or it's just my imagination?
thanks.
potentially it could
btw, if it is a CDRW disc, they eventually degrade so it isn't a good idea to keep critical backups or things on them.

What distro are you using? I use MDK 9.1 on a test machine at work and I have had some problem with the Input/Output error on my CD-Rom when my co-worker mounts or unmounts too many times. Check your /etc/fstab file.

If you put your notebook up on a ledge, so that the edge closest to you is on one surface, and the edge farthest away is on a higher surface, and then blow a fan underneath the keyboard, you can fix a lot of heat problems.
Most of the time it's that massively hot because Windows knows how (using ACPI usually) to shut the CPU down into an advanced sleep state (not just executing HLT until the next interrupt, like the basic Linux kernel does ATM). This is what Intel used to call "SpeedStep" (and they still might, I don't know).
There is support for this in newer kernels, but I don't know if it's only in 2.6.X, or if it's available at all in lower kernels. I also don't know how well it works. But in the meantime, if you can get air moving underneath the notebook's keyboard, that should help a LOT.
I'd check your hardware, especially fans; that sort of heat increase shouldn't be a function of installing Linux. I suppose it's possible that you might have some processor/disk- intensive program running which would drive up the heat a bit, but the drastic increase in heat that you describe would have me looking at other factors.

I logged out computer and waited for like 30 min until it cooled off. Then started and tried same cd again. This time everything worked fine.....
Should laptop get this hot? It gets really really hot after on for hours.
oh btw It is CD-RW/DVD and using RedHat 9.0.

how old is the CDRW disc? how long ago was it written?
i have had them degrade in as short a time as 6 months.
i don't use CDRW at all anymore.

It is CD-R. (I never used CD-RW disc for cost reason... :o ). Anyway, i think it was written...... Hmmmm yeah maybe around 6months.... i think beginning of this year.
:(
But alot of older cd-r discs are working fine. and after shutting down comp, those discs that were having problem started working fine. :confused:
kinda confusing.
Anyway thanks for so many responses in short time. :p
hmm ya. CDR is fine.
i thought you meant that the disc was CDRW - i guess you meant the burner.
:)

Mmm, true- I forgot about the differences in ACPI implementations between OSes.
