I don't have much to add but I have the same problem with my TP T42. |
| 2 |
If I boot without ac and check the the cpuinfo it will say it is |
| 3 |
running at full speed (1.8 Ghz). It feels like 600 Mhz or slower from |
| 4 |
some compile tests I have done. |

If anyone has a suggestion I would love to hear it. |
