I am heartened by this because now I can replace the fan and (if it is the fan and not a wire I slapped it back together hoping it was a loose Molex connector that was the problem and made sure the connectors where solid.īut alas, the fan continues to not run and the laptop shuts down after 15 or so minutes. Not much dust and it spun freely with me blowing on it. I put my hand back there and felt the fan trying to start. When the computer shut down and tried to boot back up, I believe you helped me find the problem.įor 15 minutes or so the computer would run fine but no fan. You can also can test the HDD with Hard drive test utility Hitachi drive fitness test, if the test passes successfully, I would assume that the system board and the HDD are fine. On some models you can see this key under the Dell logo witch appears as soon as you turn on the laptop. I don’t remember the key that you have to press for Setup on Dell laptops usually it’s Esc, F1, or F2. If you can see the HDD listed in the BIOS, it’s detected properly and probably you have a software issue. Enter the BIOS setup menu and see if you can see the hard drive in there. Did you reload the operating system after you replaced the hard drive? □ If you didn’t, find the original recovery media (CD or DVD disk), boot the laptop from it and follow the wizard.įirst of all, I would check if the new HDD is detected and listed in the BIOS. I don’t know what level of computer knowledge you have and I have to ask a simple question. If the hard drive is dead, then you’ll have to replace the HDD and reload the operating system from a recovery CD or DVD. It also might happen because of a bad HDD controller on the system board, but it’s not common. When you see “no bootable hard drive found” during laptop start up, it usually means that the HDD is dead or it’s empty and an operating system is not found. Make sure that you put correct screws into correct holes. If you can boot the basic system, start assembling it back and test after each step. You already replaced the CPU, so it would be either the system board or the memory. If it still will not boot up, then one of three components is bad. ![]() You’ll have to remove the power switch board from the top cover or carefully connect it to the system board without removing, it’s up to you. Assemble everything together outside the laptop base, connect an external monitor and turn it on. For a basic system you’ll need the system board, the CPU with cooling module and the memory module. When I have a weird laptop problem and cannot figure out what is wrong, I take it completely apart and assemble a basic system outside the laptop box, right on my bench. That’s would be nice if you can find a test memory for a while. First of all, try to reseat the memory module/modules. You’ve replaced the CPU in this model, so I assume you know how to take it apart. How to troubleshoot and fix laptop video problems That was my first experience when improperly plugged video cable prevented entire system from booting. The laptop started perfectly fine as soon as I plugged the video cable back in place. ![]() The video cable was half-way out from the connector on the back of the LCD screen. Bingo!!! I wasn’t very surprised, but I was very happy. The next logical step would be opening up the LCD display assembly and check if all connectors are seated properly. Now I know that the problem is somewhere inside the display assembly (of course, if the video connector on the system board is fine). I unplugged the video cable from the system board and the laptop started fine again with the external monitor. So, the only part that I added before it failed was the LCD screen assembly. The laptop failed to boot again with the same symptoms. ![]() After I assembled everything back, one more surprise was waiting for me. Just in case I restarted it 3-4 times and each time I got video on the screen. I opened up the laptop case, removed the LCD screen assembly and reseated the video card and… Surprise, surprise, the laptop started fine with an external monitor attached. Nothing helped to start the laptop normally. I tried to power it on for a few times with the same result.įirst of all I tried simple stuff: remove the battery and start the laptop with AC adapter plugged in, reseat and swap the memory module, remove the hard drive, the DVD drive, the wireless card. ![]() After I pushed on the power button, fans started spinning and were active for a few seconds and laptop just turned itself off. I plugged the AC adapter and tried to turn on the laptop. ![]()
