754n will not hold memory when shut down and powered back on


This is a little confusing. Memory clears out when you shut down your computer. When you start back up, you'll start filling the memory with what you are doing. There is no way to recall what was in memory. var fctb_tool=null; function FCTB_Init_e1fd0454766b4afcbb0ab2235b4516a3(t) { fctb_tool=t; start(fctb_tool); }

Computer tower started beeping

RE HP Pavillion ZE4800 Laptop When I switch on I here the fan start, the lights come on then it appears to shut down and re attempt to start again This occurs over and over and the PC never boots fully....


I have same notebook and similiar problem. Mine runs for 30 min then shuts off completely in like 20 seconds. I added a $10 usb powered laptop cooler pad and bingo, runs now for hours no problem. On all computers I know the cpu heat temperature has a threshold, if it goes too high it will shut off. I think my fan doesn't kick on fast enough to lower the temperature and cool the processor. On yours it may be a fan that doesn't work or is working at the wrong time and the circuit shuts off the system. Shouldn't be terribly expensive maybe $60 to repair from a good technician..good luck

NO POWER


Hmm. Well, that doesn't make sense, as your monitor should power on even if isn't hooked to the tower. I'm out of ideas.

No power


Have you plugged both of these into the back of the tower? Ensure the keyboard is in the appropriate plug-in, and the monitor's power cord is plugged into both the wall and the monitor itself.
