This sounds like a USB problem. If there is a short or damage within the port the computor will detect it and prevent it from starting. Usually it's a USB port you always use. This may help, Plug in the mains charger and remove all USB devices. This will confirm weather its the computer or a USB cable/device. If the computer still doesn't start, get a bright light and a magnifying glass and look inside all the USB ports on the computer. In the middle of the port there is a flat plastic piece with 4 metal contacts attached to it. Check to see if they are bent, twisted or flattened in any way and with a pin or other suitable pointy device, attempt to straighten any damaged contacts. If you cannot get the contacts aligned, just try to get them away from each other and away from the wall of the port, then insert a piece of card or folded paper above and below the contact strip and tape them down. This will insulate the port and stop a reoccurance of the problem. You should find the computer starts (with a few complaints from windows) normally. this has worked for me 9 times out of 10 for this problem.
Good luck.

Toshiba Satellite L655 Not Switching on


You mentioned that it won't turn on with the charger (without the battery). Does this mean that it turns on if the battery is in?

If it turns on with the battery, then you need to replace your AC adapter.

Alright, not sure if this will help, by my understanding is that you are saying that when you power the computer using the power supply adapter, nothing comes on? Then when you have your battery installed on, then there are lights blinking from your battery charger LED amount of times. In this case there are no promblem with your laptop and it is your power supply adapter that is damaged and will need to be replaced. It is not charging the battery. The battery is still good, but does not have enought charge to power up your system. You can find a charger on ebay for a good reasonable price compare to getting it from Hp. I hope this can help you.

Presario f700 no fan/lights = nothing at all. The charger works


Sounds like the power converter. The power input and the battery are single voltage. The computer requires multiple voltages which are generated by a power converter. If you have installed this motherboard, ensure the connections to the power converter are correct.

Lenovo z51t, no indication of life when power up


Try this. Turn off unit. Unplug charger. Take out battery. Replug charger - not battery. Turn on computer. If it comes on the battery has a glitch and should recover after an hour or so. If it doesn't come on, the unit needs to see a reputable computer repairperson.

Good Luck
