| 200951 | 2003-12-15 23:40:00 | One of our work PC's is reporting a power management error on bootup. Upon inspection the to Negative DC Values have fallen outside the range of acceptable. Referencing Scott Mueller's Upgrading and Repairing PC's (15th Edition) he infers that the negative DC Values are possibly not worth worrying about, however the monitor on the computer concerned shorted, and caught fire last week, and I am just trying to clarify whether the two are connected in any way. Can anyone provide me with more information as to whether I can ignore the error message on the short term, or should I quickly replace the Power supply. Peter |

Try to find out what the voltages actually are, and /or see if there are any options anywhere to for setting the voltage levels at which warings are given, if so you could widen the range so you dont get the error message :) |
