We replace the existing power supply (model no. L305P-01) with a new power supply (model no. N305P-06) and the computer will come on put we are not getting a signal to the monitor. Are the two power supplies similar? Really not sure where to go next and any help/direction would be appreciated.
These units should both work on a 755 Mini Tower. The DL2032 battery may need replacement.
Take out all ram and it should beep low and slow.
beeep beeeep beeeep beeep
Then add 1 ram stick.
Sort thru each chip one at a time which should be matching pairs of ram.
I re-reseated the memory and now the monitor is working. However, the back USB ports will not work for the mouse and the keyboard. I plugged the mouse and keyboard into the front USB ports and they are working. Any clue as to why the back USB ports would not be working?
yes both fans are spinning and the computer seems to be working other than the back USB ports which were working before the PSU upgrade. For some reason reseating the memory seems to have brought the computer back online.
