Dell laptop fan not spinning

After installing solid state on Dell n4010, the screen beeps 4 times and the fan does not move.

There are currently two main reasons for the black screen of the computer. One is hardware failure; the other is Software conflicts, and the difference between the two mainly lies in the location where the black screen occurs, that is, whether the black screen occurs when the machine is turned on, or whether the black screen appears during use after the machine is started normally.

The computer starts up with a black screen, the power supply fan and CPU fan do not move, the indicator light on the motherboard does not light up, and the computer does not respond in any way. At this time, you should first check whether your power socket is powered on, whether the various power cables are good, and whether the connections are normal. If confirmed, please replace your power supply and try again.

The screen doesn't respond at all, not even a single letter. It could be that the motherboard is burned, or the connector is loose. The fan is broken. Under the condition of self-protection of the CPU, if the fan is not working, the CPU will stop working to prevent burning out.

Dell notebook fan does not turn and flashes red light

1. The keyboard light does not light up. First, wipe the memory stick with an eraser and check whether there are any burn marks on the gold finger of the memory stick. Replace the memory slot. Check the capacitors and resistors on the motherboard to see if there are bulges in the capacitors and whether there is a burnt smell on the motherboard, and clean the dust on the motherboard.

2. If the power supply fan does not rotate, it is recommended to remove the power supply and send it for repair. Do not use it again. It is easy to cause major problems. If the fan is not burned, the power supply circuit is faulty, which cannot be repaired by ordinary users.

3. What do you want to ask is the reason why the Dell laptop beeps once when it is turned on and the fan does not rotate. Is it caused by a fan failure?

4. Problem analysis: There are two situations when the monitor has a black screen: the screen is not powered on (the power indicator light is not on) or it is powered on but has no signal or displays "no sighal". The former indicates that the power supply is blocked or the power cord is in poor contact or Damage, the latter is usually caused by poor contact of the memory module or monitor data cable, or damage to the memory, graphics card, monitor or data cable.

5. First check whether the power button or restart button is stuck, and then eliminate problems with the memory, power supply, and motherboard.

The Dell laptop beeps 2 times when it is turned on, 1 long and 1 short. The beeps are continuous. The fan rotates first and then does not rotate. The screen does not light up. Please...

Hello, this is definitely the case. It's hardware damage. It is recommended that you bring your computer and go to a Dell after-sales service point for testing as soon as possible, so that any problems can be solved as soon as possible.

If the fan rotates, it means that the power supply has started. There is no image on the monitor. The computer cannot enter the normal working state. It means that the computer has not passed the system self-test. The motherboard BIOS settings have not been output to the monitor. The fault should be in the motherboard, graphics card and on memory. But sometimes inferior power supply and damaged display can also cause this fault.

The reasons are as follows: The computer keeps beeping when it is turned on and cannot be turned on. This situation is a BIOS alarm. You can repair your computer based on the sound characteristics of the alarm. 1 short, the system starts normally, indicating that there is no problem with the machine; 2 short, the routine is wrong, please enter CMOS Setup and reset the inaccurate options.

The first type is the Award 0 type motherboard: it is set up like this: when the computer has just started: press the "DEL" key or the "Delete" key and don't let go (of course, some computers also have ESC, F1 , F2. F4, F11, but most computers are installed DELETE.

) The BIOS setting of AWARD is: long beep: the memory module is not tightly inserted. 2 short: The system starts normally. 2 short: CMOS setting is wrong and needs to be reset. 1 long 1 short: memory or motherboard error. 1 long 2 short: Monitor or graphics card error. 1 long 3 short: keyboard controller error.

What is the reason why the fan does not rotate after the G mode of Dell G3 is turned on?

In addition to the possibility that the fan does not rotate due to excessive dust, it may also be that the fan shaft is rusty and inflexible. It may be dismantled. Turn off the machine and apply lubricant specially designed for small motors.

You are not running high-performance mode. When the processor and graphics card are running at high speed, the fan will run at high speed.

It is possible that the switch system is broken. Find the battery icon in the lower right corner of the screen. Right-click the battery icon and select Battery Options. After clicking, the settings window will pop up. Find the change settings plan and click it. After clicking, enter General Settings, find Change Advanced Power Settings, and click.

Excessive dust jammed the fan bearings, causing the power supply fan to not rotate. Because the environment where the computer is located is relatively dusty, or the computer has been used for a long time and we have not cleaned it, the multi-wire power supply fan may not be able to rotate due to excessive dust.

If your laptop doesn't spin, you should first consider whether the fan is broken. If it is broken, you can only have it repaired or replaced. If the fan works normally but does not rotate, there may be three situations: a. There is too much dust inside the fan.
