A commom power problem with laptops. To determine if it is the power socket on the laptop is the problem, plug in the adapter into the laptop and wriggle the plug and look at the charge/power LED on the laptop. If the LED flashes as you wriggle the plug then :-
The problem is the power socket on the laptop, it may caused by a dry solder joint and needs to be resoldered or the power socket may be faulty and needs to be replaced. Either way to fix this, it requires the laptop to be dismantled to get at this power socket. Get a quote to repair, as it could cost a few dollars.
If it is a faulty cord/plug on the power adapter, this can be checked with a multi-meter. When you connect the multi-meter probes to the power plug the voltage should be steady and the reading should be slightly higher then the voltage that is printed on the label on the bottom of the power adapter. If the voltages fluctuates as you wriggle the plug then you have a broken wire in the plug. Replacing the plug would not cost much.

If these tests did not resolve your problem, then you could have a motherboard problem. A replacement motherboard may not be a cost effective solution. It may be better to put your money towards a new laptop.

My advent laptop wont power up


The only way to check the charger which it looks like is

a) When you plug in the charger to the laptop are there any lights that come on anywhere on the laptop ( if so its not the charger )

b) Plug in an external monitor to rule out the screen ?

My TV "Dynex DX-LCD37" shut


Since the TV is new I would suggest that you must not attempt to tamper the TV and give up the warranty on the set. So the best is to have an external check, remove the power supply and let the voltage drain off in the set and control panel, depress the control panel /start /standby switch/prog. switches.
If the set after this reset still prefers to shut down after a time period then there is a hardware issue on the processor section and it can be relative to hanging of the system.
I would request that you file for warranty free service immediately.

The laptop wont charge


Just because the light comes on does not mean the charger is charging. You will have to use a meter and check the actual output of the charger. The problem could be the charger , charger plug, cables or battery. Start the checks with the plugs and cables and go from there. The light can come on but no power going out to the battery.

Battery charging issue


Check your mains adapter plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced.

If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.
This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. I suggest you get a quote first.
