You didn't mention the brand? First, take out the battery and plug in the AC adapter. Does it boot?
Leave the battery out of the computer a couple of hours, now put it back in and connect the AC adapter. Does it boot? If you still get nothing the computer needs to see a reputable repair person.

SOURCE: Will not boot up

this is motherboard hardware issue
1) first all you need take out all devices like HDD DVD, wireless card then try turn it on if noting yet
2) change RAM stick that you have done
3) check DC PWM standby status, like 3V/5V/1.8V which should be appear before power on.
if no 3V/5V DC output, check this PWM circuite like MOSFET or PWM chip.
if you find 3V/5V, so need check 1.8V DC output and 1.2V that chip fail also cause nothing turn on.
all steps need diagram check where the chips and componenets on your board.
hope help you something fixed, please take a rating let me know how much helped you thanks! keep in touch your question

Hi,

Take out the battery and try booting the machine on AC power only. If the machine boots up then let the operating system load up, the shut it down. Remove the AC jack and put the battery back in again, then power it up.

If it boots all is well if it doesn't then there could be a problem with the battery.

If the laptop won't start on AC power, what you could do is remove the system memory, clean the brass pins and the slots and then re-seat them/it.

Then try to turn the machine on.

Good luck.

I would suggest to remove Hard Drive and RAM. Then try to turn on. If it will beep and/or show any errors then you have faulty RAM and/or hard Drive. If it still blank, then most likely motherboard gone bad.

The motherboard seems OK as it is displaying signs of life. The Monitor should display something before booting up, which it is not.Please do the following. 1. Remove the RAM and reinsert the DIMMs into their sockets and boot up. 2. Disconnect the HDD data cable from the HDD and the motherboard and reconnect. Boot up. 3. Disconnect the monitor and reconnect. Boot up. At boot up press F2 and set the PC to default settings. Boot up. Later when you want to apply your settings, keep noting down what you did when.
