Anyone know what the power consumption of an internal laptop CDRW in write mode is compared to a DVD-ROM drive reading a disc? I got in a debate with someone who claimed that burning CDs on battery power would leave a battery life of "15-20 minutes". I said that there is no noticable difference on my ThinkPad between battery use while reading from a CD at 32x and burning a CD at 4x. He came back with the following about a PCMCIA CDRW from Toshiba:
<<Utilizing a unique Power Management System, the PORT-Noteworthy Slim line
CD-RW/CD-ROM Drive is completely mobile (in read-only mode), drawing what
little power it needs from your 16-Bit PC Card slot. With this power
management system, the NWCDRW1 only draws power when it's needed, CD-ROM
write mode requires the use of the supplied AC Adapter. During idle times,
the NWCDRW1 requires almost no power and thus, will not cause a severe drain
on your notebook's own battery.

That's odd... they claim a "severe drain on your notebooks own battery". I
wonder how that got in there?>>
I really don't think that a CDRW draws that much more power than a CD-ROM or DVD-ROM drive draws while accessing data, am I way off base here or am I actually close to the truth? Thanks. FYI, this is also posted in General Hardware, I just figured instead of asking the experts to go to the thread, I'd take the thread to the experts.
