1. Controleer of er geen vreemde voorwerpen, zoals stof of papier, in de weg zitten waardoor de voorkant niet goed kan sluiten.
2. Controleer of alle schroeven en bevestigingen goed zijn vastgedraaid en dat er geen onderdelen los zijn.
3. Probeer de voorkant zachtjes te duwen of te trekken om te zien of dit helpt om deze te sluiten. Wees voorzichtig om geen teveel kracht te gebruiken om beschadiging te voorkomen.
4. Als het probleem aanhoudt, is het mogelijk dat er een probleem is met de hardware van de computer. In dit geval raden we aan om contact op te nemen met Dell voor technische ondersteuning of om een professioneel reparatiebedrijf te raadplegen

Are you using the Touchpad or external mouse?

It sounds like you are experiencing an issue with your Dell OptiPlex 780 computer where it is shutting down unexpectedly. There are a few potential causes for this issue, and several potential solutions that you can try to resolve it. Here are a few steps you can try:

1. Check for updates: Make sure that your computer is up to date with the latest Windows updates. Sometimes, these updates can fix issues with the operating system that may be causing your computer to shut down unexpectedly.
2. Check for hardware issues: Make sure that all of your computer's hardware is properly installed and functioning correctly. If you have recently installed any new hardware, it's possible that it could be causing the issue.
3. Check for malware: Run a malware scan to make sure that your computer is not infected with any malicious software. If you find any malware, remove it as it could be causing the shutdown issue.
4. Check for overheating: Make sure that your computer's internal temperature is not too high. If it is, it could be causing the shutdown issue. You can try cleaning the inside of your computer and making sure that the air vents are not blocked to help keep the temperature down.
5. Check the power supply: Make sure that your computer is receiving a stable power supply. If it's not, it could be causing the shutdown issue.

If none of these steps help to resolve the issue, you may want to try contacting Dell for further assistance. They may be able to help you diagnose and fix the problem.

1. Check the cable with the blue connector. Make sure it's plugged well to the back of the computer.

2. CHeck the light on the CPU's power button. If it's solid green, press the numlock key on the keyboard. Tell me, if the numlock light on the keyboard turned off or on. You can press it again if you didnt catch anything.

3. If there are no lights on the keyboard or the computer when you turn it on, the computer is the problem.

Just post here what lights are present or what happens when you press the numlock key.

the older pc probably needs a usb 2.0 port to run docking station. the manual on the docking station should tell you. you may need to install a usb 2.0 pci card in your older computer for it to work.

If your E210882 motherboard powers on but does not produce a beep code, even without RAM installed, this could indicate a problem with the motherboard, the power supply, or the CPU. Some potential causes for this problem include:

• The motherboard may be faulty. If the motherboard is not functioning properly, it may not be able to produce a beep code even if the CPU and power supply are functioning properly.
• The power supply may be faulty or not providing enough power to the motherboard. Check the power supply and make sure it is functioning properly and providing sufficient power to the motherboard.
• The CPU may be faulty or not properly seated in the motherboard's socket. Check the CPU and make sure it is properly installed and functioning properly.
• The BIOS may be outdated or corrupted. Check the BIOS version and try updating it to the latest version to see if this resolves the issue.

If you are unsure how to check for and address these potential causes, you may want to consult the user manual for your E210882 motherboard or contact the manufacturer for assistance.

My computer is not working

Hi,


If possible could you check output voltage of the charger with a multimeter? If you can get output voltage, then might be something wrong with laptop battery charging circuit. Contact Laptop Repairing Engineer.

Hello,You can do a system restore in your computer to revert it back to the known good condition.go to start or pearl > Accessories > System tools > system restore. Select the date when the synaptics driver was still in your computer.I hope this helps.

Step 1: Dell sells technology such as computers, computer peripherals and consumer electronics to both consumers and businesses. Dell sells both wired and wireless keyboards and mice that are compatible with Dell and other computer systems. Dell wireless keyboards may encounter hardware, software or other problems under certain conditions. Power Dell wireless keyboards transmit data to the Dell USB receiver, which in turn passes the data to the computer's operating system. The keyboard gets power from two AA batteries. As the batteries lose charge, the keyboard's transmissions can become intermittent. Replacing the old batteries with fresh ones will ensure consistent communication and resolve the power issue. b> Interference Dell wireless keyboards operate best and are least susceptible to interference when the user places them at the recommended distance from the USB receiver. The distance, specified in the keyboard's accompanying software or installation guide, varies by keyboard. Even if the user places the keyboard at the proper distance from the USB hub, metal objects between the keyboard and hub can create interference; moving objects that create the interference resolves the issue. b> Connection The Dell USB receiver that passes data from the keyboard to the computer requires proper and secure installation in a working USB port. If the receiver connects to the USB port improperly, or if the USB port to which the receiver is connected is faulty, the keyboard will not operate as expected. The user can reseat the receiver in the USB port, or connect to the receiver to a different, functioning USB port to resolve connection problems. b> Synchronization Dell wireless keyboards can broadcast at more than one frequency, just as their associated USB receivers do. If the two devices broadcast at different frequencies, they will not pass information to each other. The user can resolve this situation using the buttons labeled "Connect" on the top of the receiver and the bottom of the mouse. Pressing the buttons simultaneously triggers the synchronization process. b> System Dell wireless keyboards are compatible with most Dell systems. However, a keyboard may be incompatible with a given computer for reasons related to the computer rather than to the keyboard. To determine if this is the case, a user can connect the keyboard to a different computer. If the keyboard functions as expected with the second computer, the problem may reside in the first computer rather than in the keyboard.

Try with new battery pack. It may be faulty RAM too.

Take the computer to a qualified technician for trouble-shooting.
It could either be a loose cable between the keyboard and the motherboard, or it could be a dead keyboard.
Either way, it is not a "user-serviceable" part;
so, pay the technician to get it repaired safely & correctly.

1525 owners (possibly other models) DO NOT replace the mobo before reading this! Just read step 3 and 3a.

The Dell 1525, 600 series, and probably all other models using PA10 or PA12 power supplies have a power jack that uses the center pin to detect the presence of a genuine Dell power adapter. There have been considerable writings on the problems with this 3rd pin on the internet.
The symptom is that you can run the laptop when plugged in but the battery won't charge and you get a warning message that you are not using the proper power supply or it can not be identified.
The best place to see power supply status in the BIOS under battery status.
You MUST use a genuine Dell adapter, period. None of the non OEM supplies have the center pin enabled (proprietary chip).
CAUSES:
1. The power adapter sensing line can be damaged by static electricity but I find this to be rare.
2. The center pin in the power supply is loose or the wires are breaking (test by wiggling the power cord at the strain relief while holding the plug steady in the laptop - replace the power supply for $<20 on eBay.
3. The center pin connector on the laptop jack is loose - symptom is that it works sometimes and not others. Requires a full breakdown and replacement of the jack. Can be done yourself if you are very handy AND WILLING to FOLLOW DIRECTIONS which are excellent on the Dell web site. Does require soldering on most laptops.
3a. At least on the 1525 there is a sub board for the power and USB which you can get for $80 on eBay and just plugs in - still requires pretty much total breakdown. The board itself is usually the problem so replacing the connector won't help - it is in the multilayer trace from the power jack to the mobo connector. There is a bypass wiring method that requires super close tolerance soldering - I will post that if asked.
4. On some older models (P4 1 core) you can go into the BIOS and turn off Intel speed step to get the laptop running - it will run slower but you probably won't even notice the diff.
This whole mess is the result of Dell trying to protect the mobo and battery (life and fire prevention) but packing too much wiring into a too small package. They should have used a larger, 3 prong type power jack knowing how much strain is put on the power cord.
