My 4+ yr old hp g60-235dx won't power up anymore...


If the computer does not power up with either this would seem to be telling you that possibly the power cord is not working. Just because there is a light on the power supply unit does not mean the unit itself is working. Obviously the only other problem will be check the plug input as well to see if it is loose or feels wobbly is that is the case replace I would start with a new power supply unit go from there.

1996 buick riviera heater blower won't run. I jumped the motor and it runs. Turn on the switch and it won't run


you have a piece of solder broken off the controller of your hvac unit, causing power not to get to the blower motor it self. take test light and see if you have power at the blower motor. check and see if you have continuty or brake between the power wire at the blower motor and at the hvac control unit. if wires are good then the problem will lie in the hvac control unit. check and see if the blower is working at all speeds, if it works on some speeds thens the blower motor resistor.

My fridgedaire window unit A/C and heat won't come on. I had replaced an outside light fixture a couple of weeks ago and had turned off the circuit breaker that affected this unit too. Now the unit...


Plug a light into the outlet used for the A/C, if the light does not come on when reset then the circuit breaker that provided the power to the outlet need to be reset or replaced.

E system 1212 Laptop won't switch on. Power


Laptops are so integrated that usually a system failure that involves power issues such as in your case where you cant get it turn on with anything on the screen mean the mainboard (motherboard) is damaged. This usually leads to buying a new laptop or paying for the board to be replaced which usually costs as much as the laptop.
