In this article, I will summarize the most common laptop computer hardware related troubles and provide some ideas how to fix or fix them.
Issue 1
The computer system does not activate in any way
When you connect the Air Conditioner adapter right into the laptop, no lights are activating at all. When you press on the power button, absolutely nothing occurs. The laptop seems completely dead, makes no noises, no signs of life.
Possible problem:
- The adapter stopped working, and the battery has no charge left. In this situation tale a voltmeter and test the adapter. If the voltmeter indicates that it’s dead, you have to replace it with a new one.
- DC jack stopped working, and the motherboard doesn’t obtain any power from the adapter. In this situation the DC jack has to be replaced.
- Motherboard stopped working. The motherboard needs replacement, hope it’s not very costly. Otherwise prepare to acquire a new laptop.
Issue 2
Display is blank
The laptop turns on, power LED lights up, cooling down fan works, but nothing appears on display. The display is totally black and blank. The screen shows nothing.
Possible problem:
- This can be memory failing. It’s feasible one of the memory modules fell short. In this case, you can try reseating memory components to make certain they are making great contact with the port. You can attempt getting rid of memory components individually as well as examine the laptop with only one component installed. You can attempt replacing memory components.
- If reseating/replacing memory doesn’t help, attempt getting rid of the hard drive, modem, DVD drive, keyboard, cordless card, and so on. To put it simply, dismantle the laptop to bare minimum and examination once again. If the laptop still does not switch on, probably your motherboard or processor has gone short. You have to take your laptop to a Dell laptop repair
Issue 3
Laptop switches on and off repetitively
The laptop computer turns on without showing any type of photo on the screen. After a while, it shuts off by itself. After that, it switches on and off once more.
Possible Problem:
- Probably this is a motherboard failure. You can try reseating/replacing memory as I described in Issue 2. If it does not aid, possibly the motherboard fell short.a
