Samsung NP300 Laptop BIOS Flash Repair With MiniPro TL866CS Programmer
HTML-код
- Опубликовано: 5 сен 2024
- This Samsung Laptop was unable to boot as it could no longer see the hard disk or any other device to to a BIOS error. To re program the BIOS we need to un solder the EEPROM from the motherboard. I do this using a hot air gun. To re program the EEPROM I used a TL866LS programmer. The BIOS file was found on the internet (link below). The programmer comes with software to operate it but it is a good idea to visit the programmer's website to get the latest version. To re solder the EEPROM I first prepare the board with liquid flux. I chose to re solder the chip by hand! The laptop now boots up as it should. Click Here to Subscribe bit.ly/1nformatica

Thanks so much for this great video and all the useful informatons you have shared so far.
I have a Samsung laptop with the NP300E5X-A04IT motherboard and i have encountered the problem you describe in the video after i installed one of the common upgrades that Win10 usually proposes to the end user..
Anyway, i friend of mine is insisting me to flash the bios without detaching (by soldering) the BIOS chip just using the AFUDOS program. What can I say? I've already detached the chip with difficulty...so, may I ask your opinion about?
Thank you for your help and please continue this brilliant job on You tube.

In my case I could not use the AFUDOS as no devices were detected. If you can boot from USB and use AFUDOS I would do that. If not the only way is as I show using a programmer. There are less expensive programmers now CH341A 24 25 Series EEPROM Flash BIOS USB Programmer SOIC8 SOP8 bit.ly/EEPROM_Flash
Once again you're right...i had to use the G-Parted program CD, before detaching the Bios chip!
So, there's only one choice left...
Thanx one more time for your valuble advices.
WOW!!! SOLVED!
Everything went alright. I programmed my BIOS chip as shown in the video with the CH341A 24 25 programmer and re-soldered it on the motherboard.
The computer is perfectly running for almost one month...
So, i think to have a good reason to be satisfied.
Thanx a lot for your video, one more time.
Hope this comment could be helpful for somebody else.

September 2019 update.
My pc is still properly running!
Now, i think i can definitely say the BIOS update has been successful!!
I was very lucky when i found out this video.... ;-))))
Thank you for your respond, To me this information is new. At the moment I know to check some voltage on laptop motherboards like 3.3alwon and 5valwon the voltage of the RAM when the laptop turn on etc.. But I never mind that a BIOS flash was possible in this way because I do not know about the existence of the SPI programmers. Once again thank you for this video and to the future if you can do more videos about BIOS related faults that should be great!.
If you do not have an oscilloscope you can always make one : ruclips.net/video/zNTXAwxTG0w/видео.html
Hello, is it possible to program bios with ch341A without desolderig the chip from the motherboard, using the clip adapter?
I do not think so.
también debería servir para meterle una rom modeada al bios y quitar la limitación de 30 minutos del chipset HM70 para los micros i3/i5/i7 que tiene ese equipo. A menos que en otros lugares haya venido con chipset HM75, he visto NP300 con HM75, pero las de Sudamérica todas vinieron con el HM70.
¡Bueno saber! ¡Gracias por ver, que tengas un gran día! Un saludo desde Andalucia.
Any chance to read/alter the BIOS settings after the thing had booted into Windows/Linux ? My laptop do not have a working keyboard, I have to use an USB keyboard and it only works after boot.
Since the BIOS is a pree boot environment I don't think there is any way to access it after the OS loads. If you have Windows 10 or later you can try to access this way :
In ‘Settings,’ select ‘Update & security. ‘
Select ‘Recovery. ‘
Choose ‘Restart now. ‘
After your computer restarts, select ‘Troubleshoot’ from the menu that appears.
Click ‘Advanced options,’ then choose ‘UEFI Firmware Settings. ‘
Thanks for watching, have a great day!
Great video, same problem.
The ch341a programmer works in np300e4c?
It should work but I have not used it myself. There is a video here that shows how to use it : ruclips.net/video/DWWigscuQDY/видео.html
Hey, thank you for the video. I have a Samsung NP300E5Z and want to reset BIOS. Is there anyway to do it at home? Thank you!
If you can access the BIOS then select the option under "exit" to load startup defaults. Otherwise if it can boot from a CD then there is a BIOS flash tool on the Samsung website to re flash the BIOS. If like mine it cannot boot then the only option is as I have shown to remove the chip and replace or re flash it. Good luck!
@@1nformatica That was quick reply! Thank you. My BIOS is password locked and I forgot password. I couldn't find the bios flash tool but I will try that way. Thanks again. :-) Keep posting such videos.. Cheers.
You should find the firmware update tool here : www.samsung.com/us/support/downloads/
Here's something else you could try : ruclips.net/video/LlNQDttBtNY/видео.html
Hi nice video thnks. How should we choice if IC's not in supported list if tl866.
There are many newer programmers on the market now. What type of IC do you want to program? Please consider subscribing if you have not done so already!
TMS320F206PZ F22-01AFTVW this a texas instruments chip. About 100 pins
Well we are working on textile machines repairment. They are using old chip's and generally read protected. Is this new programmer devices solved protection problem.
@@mehmetyldz8407 If the device is protected then it cannot be read by any programmer.
You have a bios for Samsung NP300E5E A01US

Hello, In some cases the laptops won't turn on at all. How can be determinated that the cause of the failure is a corrupted BIOS? Thank you so much
Hi, if there is no life at all not even the fan spinning up or any leds lit when you try to turn it on I would check in order of probability:
The charger adapter plug has power, check the voltage with a meter usually around 19 volts. Wiggle the wire to see if it's broken. Second the charge socket, check from the inside for power. They are often broken or burned especially the ones which are soldered directly to the motherboard. Third check that power passes the first part of the input circuit which provides charge to the battery, check the battery voltage to see if it's getting charge. If those checks pass then it's most likely the motherboard is dead. Sometimes the heatsink to the CPU is loose or the thermal compound dried out. Usually in this case the laptop will attempt to power up and then immediately shut down. The case in this video of the corrupt bios flash is very rare. The clue was the missing boot devices. As always Google the model number with the fault you see and it maybe a common fault as with this Samsung. Good luck with your trouble shooting!
thank you for your quick response, I found this video, please watch them and leave a comment here ruclips.net/video/fd593ct9JYQ/видео.html
This was an Acer laptop with different problem. If you have an oscilloscope and can find the location of the BIOS chip(s) for your motherboard of course you can do this.
Hi there, I have the same issue. The only difference is that I can boot up but every time I turn off the laptop is does not recognise the HDD but the DVD only. I need to enter into the BIOS just press F10, choose Yes and the laptop boots again from HDD. Every time I have to do this. I have changed the CMOS battery, I thought that it was dead and this is why it keeps forgetting the HDD but did not help. I have updated the BIOS to the latest version but same issue.
That's very strange. I guess there must be a fault in the cmos backup circuit, maybe trace the circuit to the chip and check it sees the battery voltage?
@@1nformatica Thanks for the reply. Unfortunately I do not have any tools only some screwdrivers :) I can still boot the laptop it is just a bit annoying that I have to do that every reboot.
Yes, it would be a pain! Maybe change the power options to just hibernate and not power it off completely?
@1nformatica. can u pls help me to find bios file for np535u4c s02in. laptop is total brick state, no keyboard working for f buttons or the usb port.
Hi, I see a file here : cryptoinvestinternational.com/threads/samsung-np535u4c-rar.19624/

I need bios for NP300e4x not np300e5c like this. 😖
I found my BIOS here : www.badcaps.net/forum/forumdisplay.php?s=518ad9613bac61938d3242968857d647&f=40 Thanks for watching, have a great day!
I have exactly the problem but my bios will not even show up only my boot manager shows up. Can I just by a new bios chip and solder that in?
I doubt that it is possible to buy a pre programmed chip.As you have to remove the chip anyway why not just re flash it as I did?
@@1nformatica because I don't have the tools and when I look on www.bios-chip24.com/epages/63730052.mobile/seca7cc7ecbfb/?ObjectPath=/Shops/63730052/Products/19265 here it only costs 14€
@@1nformatica I'm just a student and don't have the in depth knowledge of how to do all this I m not a complete noob but I really don't know if I'm able to do this.
The most difficult part is the soldering. Flashing the chip is relatively straightforward. There are less expensive programmers available bit.ly/EEPROM_Flash
The only way to learn is to try!
@@1nformatica So do you think it's possible to buy a bios chip and it works or should I try to find somebody in my area who has the equipment to do it?
Does this programmer replace the svod programmer¿
It does not replace an svod programmer it is just a similar device from a different manufacture autoelectric.cn/EN/Index.html Please consider subscribing if you have not done so already!
sir do you know how to extract the BIOS bin file from the new bios update from samsung website?
I am afraid I don't, as far as I know the Samsung provided flash tool is an executable which will only run on the target machine. You can ask in the forum where I found the BIOS file I used : bit.ly/N300BIOS
thank you sir for your time :)
No problem! Hope you find your file.
skills!
Excellent!
Thanks! Did you do it?
i solve this withaut opening laptop
Then you are truly a genius!
its not about genius its about mind if you think you can do this
For the benefit of others who have this problem please share your knowledge. How exactly is it possible to flash the BIOS when the laptop can not boot?
@@1nformatica no answer....the genius has gone..
I'm afraid so! Will still have to break out the soldering iron!! 😀
