My laptop suddenly powered off. Now when I try to turn it on the lights flash on and off, but the laptop is not able to power on. I've tried turning it on with the AC cord and without the battery but it still doesn't work. It seems like the laptop is receiving power but cannot initiate, definitely a hardware problem.
I have an old HP ze 4125. It receives power but no power is delivered to the cpu and fan after turning on the power button. Not sure if it's the CMOS battery or part of the motherboard. There is definitely a disconnect between the power up button and the cpu.
What do u mean reset button, because i got a toshiba satellite pro 6100 and i plug in the power supply and all and the light indicates it is recieveing power but when i press the power button nothing happens i ahve tried holding the button down for a bit..but still

Whenyou connect the power adapter into the laptop, does the power LED lightup? If not then -The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty.Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced.If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's power socket.If the power/battery LED light flashes and in a certain position this LED lightstays firm, then the power socket is either faulty or it has a dry solder jointwhere it is connected to the motherboard.This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.
The problem is most likely in the DC jack in the laptop, "common issue" the laptop must be dismantled down to the motherboard level, chances are the main board must be removed from the bottom chassis and flipped over to expose the solder joints underneath the DC jack and a resolder touch up done.
hi i wonder if the mainboard has suffered a power failure due to power shortage through electrical system that it was connected to . if the lights do not appear on the media strip below the video panel and above the keyboard, that would indicate a power failure has resulted from the power supply burn out. That being said the mainboard has suffered a electrical sudden power down. Have you tried the AC adapter to ensure it works ? I would need the entire model number and S/N of the notebook to get some feedback from HP
Try taking off the battery and pressing and holding the power key for a minute and then clean the contact points both on the battery's end and also on the laptop itself and then putting the battery back and switching it back on.......That should work. Give it a try and then lemme know if that doesn't work.....
again $ again try 3 or 4 time to powerin on with ac mode,if not powering on then try it in backup mode with support battery if u dont have battery backup then get a battrey from any other laptop but it must be same model if powering on then change your adapter and try again if then also not warking go to nearer vender or service center.
