=== MWave MDSP3780 ===
This is a IBM Mwave DSP Modem controller

=== Features ===
* Chipset: MDSP3780

|}

=== Linux driver ===
A Linux MWave Modem driver 'mwave' can be found in kernel 2.4.11 and later

In addition to the kernel driver you will need some userland utilities (MWave Manager) that can be found here: http://sourceforge.net/projects/acpmodem/

SUSE and Debian include these utilities in the 'mwavem' package.
The package is in the non-free section of the Debian archives because it includes downloadable DSP software for which no source code is available.

==Status==
*Raph Levien has collected comprehensive information about this phenomena and possible solutions in 2002 on this page: http://www.levien.com/tp600-battery.html

==Solutions==

*See this page: http://www.levien.com/tp600-battery.html

*That page notes that a firmware update whose changelog entry mentions "optimizing battery recharging" might help to correct the problem, on the theory that this update disables charging when the battery is fully charged and the laptop is using mains power. With any luck the firmware update is on most Thinkpads by now.

*According to a [http://ask.slashdot.org/article.pl?sid=03/01/30/1744214 front page Slashdot.org article], if one discharges the battery nearly fully at least once per week then the batteries will be fine.

*[[User:Samiam|Samiam]]: I did not have problems with the battery until I left it in a laptop which was plugged in all of the time; both of my batteries went from being able to hold a charge from one hour to being able to only hold a charge for about five minutes.

*It is the impression of some users that the batteries perform better if they are never charged while the computer is on. The area around the battery gets quite hot while using the laptop. Charging the battery at that temperature seems to be a bad idea.

*More a way of circumvention than an actual solution is to buy an external battery pack.

*I have had excellent success with a refurbished battery from batteryrefill.com (which I only recharge while the laptop is off).

===The problem with 600 series batteries===
ThinkPad 600 power management causes batteries to die before they should. Read more about this on the [[Problem with Thinkpad 600 batteries|associated problem page]].
