#Dell laptop n5110 screen lights up but no display free
If it still won't power-up, the motherboard has issues, and it's not worth fixing unless you have free access to parts.
This is a good time to blow-out the dust on the CPU cooling fins, too. Give the epoxy time to dry before re-assembling. So make sure it's not rattling around in the machine. It Usually stays stuck to the charger, but not always. I looks like the stud, but has no internal threads. Hold the stud with pliers to remove the screw.ĬAUTION: There SHOULD be a spacer on the Left screw hole of the power/charger board. If so, pull out the video card, and lift the power board up with it. The 3rd screw on the video also uses that same stud, so it MIGHT just spin. Also the video card is you have one of the accelerator cards like an nVidia (3 screws). You have to remove the keyboard (4 screws) and palmrest (8 screws) AND the display (3 screws) to really get in there. That junk dries-out and falls apart on non-porous materials. The card has 1 screw and is also held by one of the palm screws that passes thru it. The bext wat to fix it is to take apart the machine, epoxy it back on, and re-assemble. The "stud" that this screws into easily breaks free from the motherboard, and the board gets loose. Under the palmrest, right behind the touchpad, is the batter charger/power circuit board. Just remember you did that if you DO operate on betteriy, because it will drain faster.
Just go into the BIOS setup and set the batter mode settings to all the max settings. The 70watt will charge the batteries on an 8200, but if you run the computer with it the machine will operate using your Battery Mode energy saving settings. One is using under-powered chargers (70watts from a 2500/8100) on an 8200, which wants a 90watt charger. I have been re-building working machines from about 40-odd dead ones, so I probably have seen almost oll the issues by now. There's 2 different power issues on Inspiron 2500/8100/8200 Laptops I have seen.
