Samsung NP270 cannot boot anything

Dear Dannemand,

I am writing to You after 2 days od pain and suffer caused by Samsung e270. I will cut my story short and tell You what happened.
I have deleted factory restore and all the data from the hard drive. Now I can just power up and touch nothing because it restarts by itself.
He had no CMOS battery, I'we put one in the place.
Tried all you mentioned earlier:
-removed the battery
-removed the hard drive
-removed battery connector (cable)
-tried all OS on USB and on DVD
-tried to install win 8 on other laptop and to put it back in this

Nothing has change and I have no idea and I am losing my mind because of it.
Help Pls

Thank you

 

Hi @Srdjan Milivojac, welcome to NBR. Sorry to hear about your problems, I understand the frustration.

I took the liberty of moving your post to a new thread since it isn't really about BIOS rollback (where you originally posted).

Unfortunately I am away from my PC all day, so it may not be till tonight or tomorrow I can look more into this. Meantime, please check the recent thread linked below, as your problem sounds very similar. That thread and the links in it may very well have your solution.

Also, please tell us:

1) Your full model number, which is usually printed under the bottom.

2) Which Windows version was on the laptop from factory.

3) Whether you are able to enter BIOS settings with F2.

I'll get back to your later with my best recommendations. But again, your solution could well be in the thread I linked.

 

Model is: NP270E5G-K03CH
Windows 8 was installed.
I can not enter bios, it restarts no metter what I press.

Thank You in advance

 

Thank you for the update. I am afraid that means your NVRAM (like CMOS) is probably corrupted, and your computer is semi-bricked. You probably already suspected that.

The thread linked below is where we have the most extensive discussion of this, including a summary in post #7.

http://forum.notebookreview.com/threads/samsung-series-7-np700z5c-s03ca-my-last-hope.762595/

The way to clear the NVRAM is using the BIOS flashing utility with the /cvar /patch parameters, as described in that thread. But you need to be able to boot something in order to do that.

Your best bet is to keep the HDD disconnected and try different ways to format a USB flash drive containing WinPE. When turning on the computer and it doesn't find an HDD, it will eventually look for an external device. If the device is formatted correctly to match your BIOS/UEFI settings, it will usually boot. You then use that WinPE to run the flashing utility. But formatting that USB stick correctly is often where users have difficulty.

Again, this is all discussed in great detail in that thread.

I realize you've already spent much time on this, but do study that thread carefully, as it contains many suggestions and cases from various members who suffered the same problem.

One other recent suggestion (which hasn't been confirmed yet) is to connect an external USB keyboard and use its F-keys during boot (F2 for BIOS, F10 to boot external device etc). However, even getting into BIOS settings may not solve anything in itself, except to change settings that may make it easier to boot an external device.

Please keep us posted on your progress. If you post in the linked thread there is a greater chance that other survivors will see it.

 

How can I determine current bios version and where can I find the new one?

 

I don't know a way to determine the BIOS version if you cannot enter BIOS settings with F2 or have a running Windows. That is why your focus should be on booting some form of Windows -- typically WinPE from a USB stick or DVD.

Once you are able to run some form of Windows, download and run Samsung's BIOSupdate.exe (see the opening post of this thread). If you are NOT already on the latest BIOS version, it will allow you to update to the latest AND clear your NVRAM in the process, which should solve your problems. We recommend you save the BIOS update file and run it outside BIOSupdate.exe, as described in that OP.

If you ARE already on the latest, BIOSupdate.exe won't do it for you. You will have to use the guidance in the BIOS rollback thread for how to determine the latest version, download it, extract it, and run the flashing utility to clear NVRAM. You don't have to force flash the BIOS as described in that thread.

That is the brief summary. The details are in the thread I linked in my last response (again, here, with a summary of the steps n post #7).
