Try lifting out and re-seating the card in its slot. Try uninstalling and re-installing the driver for the card. Note: You might try using DDU_Display Driver Uninstaller app to completely remove all traces of old, possibly corrupt driver. If neither helps then replace card.

You need a screw extractor set. They are not very expensive. Make a starter hole with a small drill bit. Then place the extractor tip in the starter hole you drilled. Slowly turn the extractor counterclockwise and press down until you feel the extractor threads bite into the screw head. Turn the extractor slowly to back the screw out enough to grip it with the locking pliers and finish removing . If you are not used to this sort of work “slowly” is the key word here. Don’t rush the job and rest frequently. Watch a few videos on the web if unsure of what you are doing..

Probably a cable not re-connected properly. Asus MeMO Pad HD 7 Repair Slowly go over it again.

Hi Hanna, Have you downloaded the pdf service manual? You might find it useful. Shows all screws, etc. https://usermanual.wiki/Lenovo/330s14ikb... The connector with no ribbon cable connected just the the left of your yellow circle is connected in the service manual. I would investigate this. It seems to come from under the battery. The black and red wires you mention are for the RTC or cmos battery, which stores the BIOS or UEFI settings and the time, but this would not stop it powering on. It is vitally important that all cables are correctly inserted. All the parts of the machine are interconnected and dependant on each other. The problem may be that some thing you did incorrectly the first time you have repeated each time. Read and study the service manual and review what you have done….oh and always shut down and disconnect the battery. I still suspect your problem is just a cable especially as you get no power lights what so ever. Let us know how it goes. Everything has a cause. Every problem has a...

You don’t say which motherboard you have. That helps the helpers. Which model, are you using a built-in Ethernet or one from an add-in card? It may just be that the driver is incorrectly installed - often the case on this forum. Go to the Control Panel and click on “Device Manager” and then look for “Network adapters”, click on it. You are looking for the one that does not say ”WAN Miniport”. It may have an exclamation mark (!) on it. Alternatively you may see something under “Other Device” with the exclamation mark. Which ever unistall it and reboot your computer. Go back and look in the “Device Manager”. What do you see?

Turn off laptop, if not ready off, unplug the charger and take the battery out. Hold down the power button for 30 seconds. Now just plug in the charger and turn on. Does it start up? Yes then battery is probably dead or defective.

First, blow out dust through the side vent with canned air - with the computer turned off and battery removed, of course. See how termperature is. Second, replace hard drive with an SSD regardless. Then see how the temperature is. It is doubtful you would need a new laptop. With respect to judah, re-doing the thermal paste is probably not needed and really, I would say, only a job for techies. I’ve read too many cases of people having serious trouble after attemting this. I would go step by step checking temperature after each one

First Step: Unplug the charger and take the battery out. Press and hold the power for about 10 seconds. Do not install battery. Plug in the charger and press the power button. Does anything happen? Lights, fan, screen, etc. Oh and never, ever clean ANYTHING in a computer or any electronics with water!!!! Second Step: We will seee.
