Re: Compaq Evo doesnt turn on.
When you plug the laptop to the power adapter, you should see the indicator led lit up telling that it has good connection to the ac adaptor. It wont turn on because either there is a loose connection to the power adaptor and hasn't been charging the battery, or the power adaptor itself is bad. Check the power plug with a miltimeter, it should be around 19 Volts.

When the power button blinks do you hear the laptop fans run on full speed? If that happens its because your laptop is overheating and is trying to cool down. It will not turn on until it cools down to protect from damage due to heat.
Use your laptop on a hard surface and dont block its vents with anything. If you want to use it on bed keep it on a laptop cooler or a thick book to allow ventilation.
If laptop doesnt turn on at all, the motherboard might be damaged. Take it to repair shop and check whats wrong.
If you battery is totally dead you need a replacement unit - remove the battery power the unit up using external power pack then refitt the battery - if it won't charge the battery is dead. get a new battery
Yeah it could be. Always use the correct adapter mentioned for your laptop. Otherwise it could harm the inner wirings and the motherboard. Always go for the right adapter. If it was any motherboard problem, atleast it would've blinked. So this might be the problem of your adapter or may be of the power button.

hi, first check the keyboard is on (there is power on for the keyboard and mouse device in the newer type of laptops) and while the windows start before boot see the num light is blink and the power on will blink. if it will not blink. Goto the bios setup and here while you switch on the system press the DEL or F2 key. it will goes to the bios setup and see the keyboard is enable. if it will not work then you have check with the other usb or ps/2 keyboard connect it and try it . if prob comes again inform to fixya.com
