My notebook have power but near is no display, what seem to be the problem?

Answer:

If your system sounds approaching it's powering up OK ( hard drives running, fan running, power light on, etc. ) & you own checked that the monitor is powered up + cable securely connected at both ends, you may enjoy a faulty / weakly seated graphics card.



Also, if you have an onboard card + a seperate VGA card within your system, check that the output hasn't switched to the other card. This sometimes happens if BIOS go skewy & re-enables the onboard card when it was disabled.
If your get hold of continues BEEP sound when you turn on your PC after the problem is with RAM. Check booting by cleaning the RAM or by placing the RAM contained by other slot or by replacing a new RAM.
