No, I do not know where is a reset pin of BIOS.

Try to disconnect NVRAM battery.

Wait 15 minutes and reconnect again.

To reset BIOS this NP530U3, only disconnect all power supply (MAIN battery, CMOS battery and power source). And hold press POWER button for 1 min.

I try it but don't work, do you know another way to do this

I have seen many screens with model number LTN140AT21-XXX for this laptop. My laptop NP530u4b has a screen LTN140AT21-802. I would like to know if I can use a LTN140AT21-002 screen, or if only is good a screen with number LTN140AT21-8.

thanks for your help.

My notebook gives the power but doesn't give me display can anyone help me with this problem?

Same problem of mine. Samsung service tell me that mother board is failled. And is very expensive to replace mother board.

Buy another notebook.

Jose Gustavo Abreu Murta -

Probably the LCD panel failed, or the LCD cable. Try connecting a VGA cable or HDMI to an external monitor, boot your computer, wait until Windows starts, and see if there's anything on the external monitor. If you can see your Windows session, it means the motherboard is fine, the LCD needs to be replaced. Those are easy to find and cheap on eBay

if someone is still out there with this 3 year old laptop, could a daring soul try swapping the i5 board (np530u3c) with the a6 or a4 one(np535u3c)?

i am quite confident that upgrading my a4 to an i5 will work.

The external ports are the same, the internal connectors are the same; the speakers, too.

The only thing that might give trouble putting an np530 motherboard in an np535 laptop would be ever so slightly different lcd model and maybe a different wifi adapter( i heard that it was intel centrino for np530u3c and my np535u3c has qualcomm atheros).

the rest is quite identical, unless the i5 version uses synaptics touchpad, which might not work on my elan. Even so, samsung's drivers for the %#*@ thing even have two separate folders for the two touchpad types, so to !&&* with it.

I just want to know if my 130$ worth of broke student money will do anything on it.

Hi - funny to see this thread active just as i am looking at it. Sorry to hijack your serious question with a stupid newbie one but could you tell me if it is possible to replace the 24gb SSD? the SSD drive has failed but if possible i would prefer not to replace the whole main hard drive. Having taken the HDD out though i cannot see where the SSD is?

Alex Hemingway -

i think u have a hybrid drive. google is your friend search it

donkervoortjes -

I've been searching everwhere for the answer to the ssd/hdd hybrid question. I have had this question for a long time and no one knows the answer! I couldnt find the ssd or the ram anywhere. I have tried the hdd in another laptop but no sign of the ssd! Finally finding this page I have the solution! Check the picture of the back of the motherboard... there is the onboard ram and also the onboard ssd!!! Thank you very much for putting my mind at rest!

Hi everyone. My hinge broke and with it two cables. A white one and a black one. They both were wrapped together in a thick isolating cables. I thought that it might have been my wifi antenna, but it is still werking. Same as all the other functions. Could anybody tell me what those cables were for? And if i should try to fix it.

Jochem Labots - Reply

those just boost your wifi receiving range.

SSD: if you look at the underside of the motherboard (not the side you can see when you remove the back panel, but the one facing the keyboard), you will see a big Sandisk chip containing the 24Gb SSD. Also the motherboard has 4GB of Ram, plus the DDR3 card

Question about replacing AMD A6 -motherboard with Intel -motherboard: it can be done. I just replaced my A6-4455M with i3-3217U, and everything works great. If you're running Windows, you might want to reinstall, but since I run Linux on mine, everything worked when I booted it up.
