Re: No power going into the laptop
A fault I frequently come across is the power socket either breaking up, breaking out of the motherboard or more often now just an array of dry joints causing all sorts of odd problems. Build quality of laptops is rubbish these days - they have to cut costs to save money because of the lower overall price of laptops

Toshiba Satellite laptops often have problems with their power connections becoming loose and losing contact between the positive pin on the DC power jack and the motherboard. Laptops are not designed to operate on the battery when the AC adapter is plugged into a viable power outlet. You will have to disassemble your Toshiba Satellite laptop to repair this problem. This task requires a thorough knowledge of laptop repair and safe soldering practices.
1. Disassemble your laptop according to the instructions for your specific Toshiba Satellite laptop model. Cut the plastic supports off the base assembly with a knife.
2. Cut off the plastic wall that encircles the mount opening with the knife. Extend the circumference of the hole by carving it open with the knife to make it wide enough for the new jack.
3. Bring the ends on the negative lead for the jack together and cover the ends with solder.
4. Remove the original DC power jack and trim the wires from the jack box with the knife, until they sit close to the edge of the jack box. Use the knife to strip the wires. Use your fingers to twist the wires together, and then coat the point where they meet with fresh solder. Locate the positive wire -- it is either red or green. Plug this wire into the positive lead on the new jack, and then find the negative black wire and attach it to the negative lead on the new jack.
5. Place the new power jack in the base, keeping enough extra space available for the plastic laptop cover and right speaker to fit back in later. Cover the negative and positive leads with the electrical tape, and then manually rotate the nut on the power jack clockwise until it will go no further.
6. Figure out which walls will stand in the way of the power jack after you secure the plastic laptop cover. Cut these walls out with the knife. Reverse the disassembling instructions you followed previously to put your laptop back together.
laptop either needs a new Cable from the Motherboard to the Screen, a
new power inverter, or a new screen. Most commonly, I have seen the
video cable get smashed between the hinges/plastic case, and this causes
the wires to break apart, leading to a black screen.
If the display comes back, slightly, when you lift the display lid up
and down, this would be a sign that your cable is bad. If you get no
reaction from opening and closing the lid, you may have a bad inverter
or screen. It is most commonly the inverter or the cable.
If you have a spare monitor, you could plug it into the VGA connector on your Laptop as a temporary solution. If after plugging the monitor in, you get no display, try pressing Fn + F5.
Does the display show anything before you enter windows? If yes, then press the key to transfer video back to your original screen once you enter windows. It should be the function key "Fn" + F5 - F8. looks for the icon which shows a monitor or says "CRT/LCD".
If it doesn't show anything before you enter windows I'm afraid your screen needs to be replaced. Good luck.
Make sure the battery has a full charge, and that it's plugged into a wall socket, then try the power button. You will get the same symptoms as a bad power switch if your battery power is very low. Other than that, the battery could be bad, or going bad. If the problem is a faulty power switch, you will have to have it replaced.
Computer was outside (cold) out of the briefcase for a period and found that when it was brought inside it created some condensation. 30 minutes with a hair dryer on low dried everything out nicely. Computer started right up.
