When I shorted the first pins (my laptop was just fine before that) it made it not booting.

When I shorted the other pins I was able to boot.

 

From my testing those jumpers will clear the CMOS data (whatever that means) and the time.

But it will not clear NVRAM settings (stuff you mess up while in BIOS menus) so it will not help with making your laptop bootable.

 

I consider bricked a laptop that displays nothing on screen. Keyboard could light up or... no.

hi arise.

wanted to ask bout nvram persistence u mentioned.

so the settings ive made in bios wont get resetted because of nvram persistence right ?

can i know how you fix ur laptop then ? what did u do ? 

until today my laptop not fixed yet its so damn frustrating, idk what to do anymore...

Changes to a systems BIOS or UEFI may cause the system to boot abnormally. If you are having trouble booting your system, you may try to reset your BIOS/UEFI settings to default.

1. Try connect external monitor or TV.

or

1. Press and hold the power button for 10 seconds, or until your system shuts completely down.

2. Power on the system.  Immediately press F2 or Delete to enter the BIOS.

3. Press F9 and then Enter to load the default configuration.

4. Press F10 and then Enter to save and exit.

hi, thanks for replying.

actually i ask on other forums aswell, and here is the answer i got :

Please do try these troubleshooting steps that may help.
- First is to do a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- If it will still load into a black screen, try connecting an external monitor and see if you'll get any display from it.
- If the screen is still black proceed with reseating the RAM's.
- Remove the RAM's off for a second then put them back in making sure everything is seated properly.
- If it will not work, I would suggest opening the laptop and reset BIOS by removing the CMOS battery for a second then put it back in.
- And if all these will not work that means that the problem may lie in the motherboard already.

and unfortunately, before iam asking here and there , i already tried all of them, and none of them works.

and now my last resort would be try shorting JRST2001 to do hard CMOS reset.

and regarding JRST2001, someone said this :

but anyway im just gonna try it.

Laptop Model : Asus N46VZ
OS : Windows 10

what i change in BIOS settings are :

• Launch CSM - Disabled
• Fastboot - Disabled
• Secure Boot - Disabled

after that, i press F10 to save changes and exit.
laptop will restart, but when restart i got black screen.
Keyboard light, Notification Light all lights up, Fan is running.

what is the possible cause ?
is it VGA ? or something else ?

how to fix this problem ?

thank you very much.

Shorting JRST2001 for me actually bricks the laptop, to unbrick it I also have to short the JRST2002 pin. Cant say exactly what is doing, didnt investigated much as I discovered it won't help me with the NVRAM persistence.

wanted to ask bout this, u said shorting jrst2001 will brick the laptop, and to unbrick it u need to short the jrst2002 too. my question is, when u unbrick it, did u get the "asus logo" / POST-ing ? 

also i get this image from french forum, and JRST2001 is indeed for clearing CMOS.

Either of them should work, add one to a USB stick and try with Ctrl+Home then Power button.

Filesystem of the rescue drive should be FAT32.

If not working, then try with another stick.  Or a sdcard in a cardreader. 

Eventually it should work...

hmm, but in the list that i showed u earlier, i got one of them right :

or, because the PhoenixTool shows 2 of them does that mean, in my usb i should copy the bios twice and rename one of them to "N46VZ.bin" and the other one to "N46VZ.409" ?

You can find PhoenixTool on digital life forum or on the net.

When you open the recovery BIOS file in PhoenixTool it will show a popup with the recovery file name that must be used.

okay, after using PhoenixTool

Try the Ctrl+Home pressed and while keeping them pressed press power button. It should hopefully attempt to boot from USB stick and reflash the bios. The bios must be on a simple USB stick formatted as FAT32. The filename for recovery can be obtained with andytools.

If this will work you will see the usb led for activity flashing differently than usual. So if usb is flashing then is only a mater of matching the filename/firmware.

The other option would be the recovery using a SPI chip programmer.

hi, i already did the ctrl+home, the usb did flash differently, but after that nothing happen, the screen still blank.

i dont know if the BIOS filename in the usb is correct or not, but i already tried a bunch of names, but nothing.

u can see all the names i've tried below :

and, does shorting JRST2001 fixed ur asus ?? because i see from this thread > https://rog.asus.com/forum/showthread.php?66837-Hard-CMOS-Reset-Solution-For-dead-G75VW

and his asus come back to life.

oh, and what is this "andytools" u're talking about ?? never heard of it.

I did a lot of combinations (without battery, with and without power cable with and without CMOS battery inside of laptop).

 

It seems that if the CMOS battery is installed, with no other power, then shorting the JRST2002 will make the laptop not POST-ing. If I short the JRST001 it will unbrick it.

 

If I remove the CMOS battery, then if there is no power cable or battery it seems I lose the date/time. But all other options are preserved in BIOS. Shorting JRST2002 will do nothing it seems without that 3.3V CMOS battery.

Shorting the JRST2001 will make the laptop reboot if the power cable is on, but no BIOS changes will be reset back to default values.

 

So... right now I am stuck, don't know if those jumpers are working as they are supposed on Asus G750.

After some more testing I can say that shorting JRST2002 and then JRST2001 will reset the system date/time back to 2009. But the settings in BIOS will be preserved, those are not erased.

hi, im sorry for bumping this old thread, but i got bios problem too, my laptop is asus n46vz, the thing is i changed some settings in my bios, after save change & restart, my screen is completely black but keyboard light , notification light all lights up. so i wanted to ask, does ur asus fixed after u do this ?
