My 8300's power button has been acting strange; it requires a few pushes to turn on the computer. The frequencies increased last few days and now it completely refuses to repond. I checked the connector on the system board, checked the cable and called Dell Tech Support; but still can't figure out what's the problem. Dell Technician suggested changing the power supply, but he is not sure if that's going to solve the problem. I am thinking perhaps the power button is not working, but I don't know how to take off the front cover to examine it. Dell Technician suggested going to a repair store, but that's going to costly and not necessary helpful. Hope someone can help me here.
I am having exactly the same problem. I have a DELL Inspiron-510m Some times it takes 5-10 minutes to play with the power button to turn the notebook on ! which is unnacceptable. I think the problem is in the power button itself, but I don't know what the solution is and I am just living with it for now ... Eduardo

Re: Power button mulfunction?
Ok, to get at the switch board, take a flat bladed screwdriver and /carefully/ lever the outside ends of the hinge covers vertically upwards. Once the covers are free (you'll find that they are attached to the blue strip), slide the blue strip and hinge covers to the LEFT and then lift. The strip should free from the chassis. The switch board should be held in by two screws (one holds a lug to hold down the keyboard) and connects to the motherboard via a ribbon cable. The part number for the switch board is printed on the upper side of the board. You might find it advantageous to order a new ribbon cable as well; both parts should be readily available from your newarest independent service centre or direct from Dell.

Does the power button flash when there is a black screen? Could be that the laptop is in hibernation mode. Go to the tray icons next to the clock, click the battery symbol, more power options, and change the settings of "turn off display" and "put the computer to sleep" to "never". Usually to get the computer out of sleep mode, you just click the power button to turn it on again. Hope this helps.
I have a Dell Studio laptop and sometimes some buttons become not responsive, including the power button. As for power button, I noticed that if you hold it for a few seconds, the laptop will turn on (at least in my case). The fix that works for me is as follows:
1. Turn the laptop off; 2. Disconnect the charger and take out the battery; 3. Wait for a few seconds; 4. Open the laptop lid (as you probably closed it while taking out the battery), push the power button and hold it for a few seconds. Nothing will happen as the laptop won't have any power, but it clears some sort of electrostatic load or whatever it's called; 5. Put the battery back in and turn on the laptop.
I used this for a few times, so perhaps it'll help in your case as well.
Computers, no matter the make or the model, have a tendency to freeze up. This typically occurs when you overload the RAM on the computer and the laptop can not process any more information. When your laptop freezes, you are not left with many options, so you'll you need to restart the system.
1.Press and hold "CTRL," "ALT" and "Delete" at the same time. Wait and see if a prompt window loads. If one does you can select the program causing the crash and close it. This allows you to return to using the laptop. 2.Push and hold the power button until the system turns off. Typically, you need to hold the power button down for a few moments before the laptop shuts down. 3.Remove the power cord from the laptop if the power button does not turn the computer off. Occasionally this can occur, in which case you need to find an alternative way of cutting the power. 4.Flip the laptop over if the power button is not turning the computer off. Find the battery compartment on the bottom of the laptop and remove it from the computer. Momentarily the computer shuts down. Leave the battery out for a few moments. 5.Insert the battery back into the computer and press the power button. Shortly, the computer restarts and begins to load the operating system.
Hi Paul. There are few possible causes for what you've described: 1. The outlet doesn't work properly - Try using a different one. 2. The power adapter is mulfunctioning or doesn't match your laptop - try using another original adapter or a generic one (make sure the Voltage is EXACTLY the same as your laptop requires and that it supplies enough Current). 3. The battery has gone bad or finished it's life-cycle - Replace the battery. 4. There's an electric problem with the power circuit on the motherboard - replace it in a service center...
There are a couple of solutions that I tried that worked for me when my computer was doing strange things. There should be two buttons on the bottom of your laptop called the STRIKE ZONE. Push that button down for at least twent seconds. Next, there is a second button that has a dead bolt icon over it. This requires you to take a pen and slide it over to the other side, There is also one more task to do and that is to slide left button. This last button is located on the left side of the laptop, on the side. And I should mention that the computer should be off before attempting this fix. Good luck.
The way you're trying to turn on the Computer is correct but the issue may be related to the Hardware and service may be required. However, you may try some troubleshooting steps to determine if the Computer requires to be serviced.
Remove the Battery from the Computer and disconnect the AC Adaptor then press and hold the power button on the Computer for 30 seconds. Then, connect only the AC Adaptor to the Computer and try to turn it ON. If the issue persists then the Computer requires service.
Two possibilities, your backlight is loose and needs checking or even replacement, or the cable connecting your screen is loose or mulfunctional. The first case if the most likely and common case. Considering how narrowly your screen connects with the rest of the computer and how on many occassions people 'just looove' to swing that screen around, it comes as no surprise that after a while it would start acting up. If you're into dismantling and reassembling computers, well, try and access the cables connecting your scree, check them and make sure they are okay, next, check your backlight and all its connections just to make sure everything is seated okay [all the above will require that you open a few things here and there] Good luck
please chek the booting sound is coming.
2.if the sound is coming then this might be the issue with display only.
3.if booting windows sound is not coming then this is the issue related with either m/b or RAM.
4.if num lock is responding(press and release num lock) then this is the issue with RAM otherwise with motherboard.
in case of clarification please revert.
Remove the plug from the wall and computer then take the battery out. After both have been removed, push the power button a few times, put the battery back in and turn it on. If it does not power up, take the battery out and then plug it in and try to turn it on.
This sounds like a weird solution, but it worked for me. I recently bought a used Presario 2500, it worked when the guy showed it to me, when I got home it didn't work two days later. I tried several tips from the web, finally I started pushing several buttons randomly. I pushed the Email (Envelope) button, and the computer powered on suddenly. Now, the Envelope button is the only button that will power the computer on. When the computer is on, that button will also bring up Outlook, but when the computer is off, that button turns it on. Let me know if this fixes it for you.
