Did you here any beep sound when on the system. If beep sound is came means check your ram.

Check weather any driver is connected & (cd or dvd) is in the system. Remove that. Now restart it.

    first off find location of rtc and remove battery for a few minutes then replace.

    if its a bios problem this will resolve that.

    check hard drive.remove and replace make sure housed properly;(when u start up if you listen carefully u can hear your hard drive doing something,if you can hear repetitive clicking your hard drive is damaaged,there should be a kight to indicate that the hard drive is accessed also,if no lights no sound then its a motherboard component problem.

    check memory cards,remove /replace.if theres no memory present,or damaged you will get a blank screen(nothing,as if you havent even turned pc on)

    if the pc has been dropped check graphics card .if the graphics card is missing dislodged or damaged you will also get nothing on screen.if this is a second hand pc youve purchased check if speakers are connected(possible reason for no beeps)

    oh forgot...rtc is on motherboard ,you dont need to remove it just remove battery next to it (looks like a large watch battery,silver)

    make sure a os disk in drive.if you cant hear any response from cd,hard drive or fan you have power failure on motherboard.

Hp 250 g1 laptop when pressing power button it flashes green but will not power on

If the light is flashing with a descernable pause, you should count the number of flashes. A search on the net should then identify what the flash sequence means, and whether or not the machine can be repaired.

I have an intermittent power-on issue with my Dell E4200. Sometimes it is very hard to turn on - pressing the power button makes the button light up, the fan runs for a few seconds, then the caps lock icon...

Try performing a hard reset on the laptop. Remove the battery and all peripherals connected to the laptop (including the AC adapter). Once everything is removed/disconnected, press and hold the power button for around 15 seconds. This will drain all remaining charge in the motherboards capacitors which usually causes this kind of issue.

Hope this help. Goodluck!

Green led mains light comes on, battery amber light rapid flash

This sounds sucky, but you may have a power-supply issue. Especially if you have had to repeatedly press the power-button. If the laptop is new, call Toshiba and see if it's under warranty. If not, find a local computer tech to test your power-supply. This problem is less common nowadays, but still an issue for some!

Hope this helps!
