You can try reseating/replacing memory as I described in the Problem 2. After a few seconds it turns off by itself. The laptop turn on without showing any image on the screen. Read this guide for bare bone system troubleshooting. If the laptop still doesn’t turn on, most likely you have failed motherboard or processor. – If reseating/replacing memory doesn’t help, try removing the hard drive, DVD drive, modem, wireless card, keyboard, etc… In other words, disassemble the laptop to bare minimum and test again. You can try removing memory modules one by one and test the laptop with only one module installed. In this case you can try reseating memory modules to make sure they are making good contact with the slot. It’s possible one of the memory modules failed. The screen is completely black and blank. The laptop turns on, power LED lights up, cooling fan works but nothing appears on the screen. Here are some tips for testing AC adapter and DC jack.Īlso, make sure to read step-by-step instructions for troubleshooting dead laptops. Otherwise get ready to buy a new computer. The motherboard has to be replaced, if it’s not too expensive. In this case the DC jack has to be replaced. – DC jack failed and the motherboard doesn’t receive any power from the adapter.

Update the motherboard system firmware to the latest version.Wait 20 seconds after applying power, before turning the system on.Memory is transitioning to a warning state.The system is still functional, but a non-critical temperature or voltage issue has occurred. For example, two redundant power supplies are installed, but one has failed or is predicted to fail. The system is operating in a redundant state but with an impending failure.The system has just had AC power applied.What is happening when I see a blinking green System Status LED? This power supply status is normal behavior. Two blinks per second means that the power supply is updating its firmware.Cold redundancy means one power supply is in an efficient low-power state, and it is not activated until it is needed. One blink per second means that the power supply is off, or in cold redundancy.What is happening when I see a blinking green Power Supply Status LED?
