EgorZindy: jumping mouse cursor problem on the x41 tablet
2009-02-01T11:34:57Z
<p>jumping mouse cursor problem on the x41 tablet</p>
<p><b>New page</b></p><div>Information about the jumping mouse cursor problem, which occurs on some X41 tablets when CPU load is high.<br />
<br />
==Problem description==<br />
<br />
When CPU load reaches 100%, the mouse cursor stutters and jumps to the bottom / middle of the screen (in Windows, just above the task bar). Additionally, left clicks may be generated.<br />
<br />
==Diagnosing the problem==<br />
<br />
In windows, it is possible to reproduce the problem by opening the calculator and typing 999999!<br />
<br />
If the machine is affected, it will quickly become unresponsive (cursor stutter) and the cursor will eventually jump above the taskbar.<br />
<br />
==Affected Models==<br />
<br />
*ThinkPad {{X41 Tablet}}<br />
<br />
==Affected Operating Systems==<br />
<br />
*Windows XP<br />
*Linux? (anyone using Linux having the problem?)<br />
<br />
==Status==<br />
<br />
A workaround is being tested.<br />
<br />
==Solutions==<br />
<br />
[[Pentium M undervolting and underclocking|Undervolting]] the CPU seem to solve the issue (see TabletPCBuzz link below).<br />
<br />
In Windows XP (and Vista?), this can be done using the [http://www.pbus-167.com/ Notebook Hardware control] utility and the following voltages:<br />
<br />
*1500MHz model: 0.748V @ 6X, 0.796V @ 8X, 0.844V @ 10X, 0.908V @ 12X, 0.940V @ 15X<br />
*1600MHz model: 0.748V @ 6X, 0.796V @ 8X, 0.844V @ 10X, 0.908V @ 12X, 0.940V @ 16X<br />
