Hi,
Is there a way to fix the loose trackpad in the NP940x3g laptop? My trackpad makes a slight click when I tap on it to click.
Thanks.
Maybe you need to replace your palm rest.
SSD Upgrade suggestions?
Hi, David,
Can you please tell me if you are familiar with the following error?
When I start my Samsung ATIV Book 9 Plus, I get the error “Windows failed to start.” To fix it, the message says I have to insert the Windows installation disc and click “Repair your computer.”
I’ve tried doing this but when it is booting up and I hit the F10 key to try and select another device to boot up from (so that it can boot up from the external CD drive that has the Windows installation disc), my cursor keys do not work so I cannot switch it to boot up from another device (only the F2, F10 and Enter keys work!). Since I can only hit the Enter key in this case, it boots up from the default hard drive, and I get the same error again.
Do you know if this appears to be a keyboard problem and can be fixed by replacing it with a new one? Or do you have any ideas on what I can try to fix this (possibly by opening it up and reconnecting something that might have come loose)?
Please let me know if you can help me. Thank you!
David
It seems your windows were damaged. You need to restore or reinstall it.
How about replacing the keyboard? I’m having a problem with that.
Can the Intel R Wireless-N 7260 AN be replaced with the Intel R Dual Band Wireless 7260?
How did you remove the SSD? I thought unscrewing a small screw next to the SSD was necessary, but it looks like I don’t need to.
Just remove one screw securing the SSD, and you can remove it.
Hi, David,
First, thanks for taking the time to publish the information. It was a great help. Do you have a post on removing the keyboard from the Ativ 940X?
Hello, Happy Thanksgiving!
Did you ever get the information on removing the NP940X3G keyboard, and if so, could you tell me where to locate it?
Thank You
Hi, I am having trouble assembling the laptop again. The screews at the front don’t seem to fit. Could it be the blue stuff on them? Any suggestions?
Hi! Could you please tell me the part number or name of the black flat cable that connects the sub-board to the main board by the fans? It has a socket-type connector at both ends. Thanks.
The part number of the LCD cable is BA39-01324A.
Hi. I accidentally jammed my headphone jack into the USB, and now it’s loose. It only works if I keep constant upward pressure on it. Doh. Do you have any advice on replacing the USB port? Is there a part number I should be looking for? Should I instead focus on soldering something back together? Thanks!
You should remove the motherboard from the laptop and the USB port.
Just finished disassembling my wife’s NP940X3G after she spilled water (most of a glass) on the keyboard. Your post was invaluable in guiding me on how to disassemble the machine. Thanks very much for posting this!
Hi, I recently spilled water on my laptop. I blow-dry it with a heat gun and leave it for another 5 hours, just in case I missed a spot. After reassembling the machine, I noticed it only boots up for about 30 seconds and then turns off. I tried using F2 to get into the settings area, which worked. The machine stayed on in that mode without any problems. However, as soon as I exited and tried to boot it up again, it only lasted for about 30 seconds. Do you have any advice?
Hi, I have the same issue here. How did you solve it?
Thanks in advance
May I know where the CMOS jumper is? I need to do a BIOS reset. Thank you!
Just remove the battery and reinstall it, and your BIOS will reset.
Hi,
Can the RAM be upgraded from 4GB to 6GB or 8GB on this model?
The memory is soldered on the motherboard, and there is no reserved memory slot, so you cannot upgrade the memory.
Does anyone know why this laptop is restarting every time I start a web browser?
Hi, can I get this motherboard?
Do you have a part number for the ribbon cable connecting the motherboard sides (It has SUB and MAIN on it), and is it in the 5th picture of the document? This has been cut on mine and I need a new one.
Thanks
Jon
Hi, I’d like to know where the soldered RAM on the NP940X3G is located, and what is the part number?
Thanks for this post. My laptop was overheating, and this guide helped me remove the motherboard to access the CPU and replace the thermal paste.
