Lenovo B575 - Shut down issues + POST loop + more help?!

post #1 of 7
Thread Starter 
Hey guys, I don't normally try to bring my issues up since it's my job to solve them but I thought I could use the community help.

Today we have a Lenovo B575 who was getting a optimizing loop and windows barely functional. As much as recovery is fun I decided a fresh install was the best option, boy was I wrong.

Fresh install froze during the restart parts and eventually never was able to shut down and wifi wasn't working

Eventually I found


http://forums.lenovo.com/t5/Lenovo-3000-and-Essential/B575-hangs-when-powering-down-or-rebooting/m-p/568641#M44843

however by now it was too late, during boot I could not access the BIOS! No matter what I tried it wasn't working, neither was boot menu.

(supposed to be F2/F12) FN+F2, FN + P, enter button, nothing works.

I figured it was stuck on HDD boot cycle so I unplugged all, took out HDD, tried to boot in order to hopefully trick it into letting me into BIOS, well...

BOOT LOOP on POST! It shows Lenovo logo then reboots, in a loop... forever. I put HDD back but POST loop stays... Reset Memory... I don't know what else to try.

I attempted to reset bios, CMOS battery removal, everything.. I'm stumped, I've never seen anything like this! Any suggestions on how to get access back into the bios? I was thinking of doing a bios update but all I have is a flash drive and no access to Windows or Bios at this point (or bios file)

Usually with a boot loop no post like that could be a dead mobo. Did you just remove the CMOS battery or actually clear the CMOS itself with the reset jumper? Generally you'll want to do that for a few minutes, move the jumper back, and then power it back up without the CMOS battery. If you still can't get a post beep then remove your ram completely and try it again until it beeps that there's no ram in there. Most likely you've got a bad stick of ram or even a bad socket.

Yea definitely hardware. I was also gonna say maybe try different RAM sticks. Might also be CPU overheating. Maybe take out the heatsink/fan and airdust? Otherwise, I can't think of anything else.

I've removed ram and turned on , no beep codes


I do not believe there is a CMOS clear jumper on laptops, I've removed battery only,

I think the bios is stuck trying to boot efi windows boot manager.. That's why it posts but then restarts.

I don't get how F2/F12 don't so anything. I've tried hold B down, etc... No avail

I'm going to order a new motherboard I guess but it might have the same UEFI/BIOS issue.

This is what happens when companies make crappy bios. I think that lenovo is a good company too but they dropped the ball here.

Anyone have any experience resetting bios or reflashing a lenovo with no OS or BIOS

I read Fn+R is supposed to jump into some recovery mode..

And yes it's 4am est. I need this machine running by 11am frown.gif

I wouldn't automatically assume there are any beep codes for such a crappy mobo (no offense). Also, when you removed the CMOS battery, make sure you drain all the power (remove battery & power cable, and push power button &/or let it sit for awhile).

If you have removed RAM completely as well as the battery (drained all power, pushed power button a few times to clear) and there are no beep codes, the mobo is gone. Unless you have a EEPROM writer I don't see how you can flash a new BIOS since it cannot boot anything, yet alone a USB with a new rom.

Sorry can't bring it back, lappys usually tend to overheat causing them to die. frown.gif

New motherboard is installed and install process is underway however the GPT / 3 partition / no reboot issues still exist


I always thought lenovo was good machine but their UEFI system is complete garbage

some more info, maybe we can figure it out

When trying to do a clean install over an existing Lenovo installation, the new OEM Windows 7 installation hangs at every reboot attempt and the power on/off button must be used to cycle the installation through to completion. Once done, the pc will not respond to shut down or reboot requests via the start menu.

The cause:
The hard drive master boot record (e.g. MBR) has been previously set up for Lenovo's configuration which calls for three partitions; whereas, a healthy OEM Windows 7 installation requires only 2 partitions ( 1 small system partition and 1 larger partition for the operating system. However, this requirement doesn't limit you ability to add an extra partition (like for a D drive) but it must be done within the proper configuration of the MBR.

The point of failure:
During the installation, you get to a point where it shows the existing partitions on the hard drive and you will see the 3 Lenovo partitions. So, if you did like I first did (delete the 3 partitions and request a format of the hard drive) it actually build 3 partitions again; however, the way they are structured is the killer on this installation and leads to the problems described above.

How do I fix this so the OEM installation proceeds normally?
You have to fix the MBR now!

Step one: Turn your computer on, booting from either your Windows 7 Installation DVD or Windows 7 System Recovery Disc. Remember, you may need to change the boot order inside your BIOS to have the your DVD drive boot first.

Step two: After the installation or recovery disc loads, if prompted, select your language settings and then continue. If you are using the installation DVD, when prompted by the following screen, select "Repair your computer."

Step three:
The computer will take a moment now to scan itself for any Windows installations, after which you will likely be given a choice to select which installation you wish to repair. Select the appropriate Windows installation from the list and then continue. If by chance a problem is detected in one of your Windows installations at this initial stage, the system may also ask you if it can try to repair the problem automatically. Just select "No" here.

Step four:
Once you have reached the System Recovery Options, click "Command Prompt" to continue.

Step five:
Now sitting at the command prompt, enter the following commands (one at a time by pressing enter) and wait for the each response. BTW, ignore the responses:

bootrec.exe /FixMbr (enter)

bootrec.exe /FixBoot (enter)

bootrec.exe /RebuildBcd (enter)

Good News! Your MBR has been repaired and is ready for your new OEM installation. So "x out" of the open dos window and the System Recovery view and your system should restart. Now go through your OEM installation again, delete all existing partitions and select "format." Now, this time you should end up with 2 partitions that are properly configured to process your Windows 7 OEM installation.

Good luck!

thank you very much, your detailed description definitely got me on my way!! however it did not work right away for me, so for the sake of other people stubbling on this post with the same problem I'll explain what I had to do :0)

I'll take over after step 5

Step six:
after deleting all partitions and creating a new one during your OEM Windows 7 install:
=> if you have 2 new partitions as Pagroundhog mentioned at this point, I guess you're on your way, continue your install.
=> If you still have 3 partitions being generated automatically then you still have the same problem.
At this point, keep the system partition & Delete the 2 other partitions.
You should have a system partition and bunch of unallocated space.
Then create a brand new partition with the remaining unallocated space & format. For me it did the trick, it generated only one partition, so that I ended up with 2 partitions only (the Reserved partition for Lenovo disapeared).
Continue your install.

Step seven:
At this point the computer still behaved the same (not rebooting) for me, so after completing the install (without updates to cut short) I restarted the process from step one which fixed the MBR this time.
Then at step six I got 2 partitions automatically as expected initially.
This will be your last install of Win7.

A non-negligeable side effect was that it fixed the wireless issue you certainly are also experiencing.
As a matter of fact on the very last install, Windows detected the wireless card automatically and was able to use generic drivers to make it work.


There has got to be an easier way to do this, I'm on my 5th install and it has same issues.

Is it possible to prep the HDD for Windows Installation (The system partition "EFI" plus the regular storage part?)

UPDATE: So I am not a member on that forum and that thread is closed but here is some more details to this process...

WINDOWS SHOULD BE INSTALLED FIRST.

Make sure on your first install you go through all windows screens, when it says restarting you have to manually restart, keep doing this until you get a desktop. When you restart F12 and click WD HDD -- NEVER USE WINDOWS BOOT MANAGER!


Step two: After the installation or recovery disc loads, if prompted, select your language settings and then continue. If you are using the installation DVD, when prompted by the following screen, select "Repair your computer."

bootrec.exe /FixMbr (enter)

bootrec.exe /FixBoot (enter)

bootrec.exe /RebuildBcd (enter)

(It may say Windows Installations found 0) That is normal

Good News! Your MBR has been repaired and is ready for your new OEM installation. So "x out" of the open dos window and the System Recovery view and your system should restart. Now go through your OEM installation again, delete all existing partitions and select "format." Now, this time you should end up with 2 partitions that are properly configured to process your Windows 7 OEM installation.

You should click restart under that System recovery options dialog box, then manually shut off and on the PC once again booting the DVD


After you boot DVD continue to "install windows" DELETE THE PRIMARY PARTITION FIRST, THEN MSR RESERVED, THEN SYSTEM

Click "NEW" for unallocated space and you should get 2 paritions

If it doesn't work, start again by Deleting all partitions, then install with the 3 partitions and start at step one. It took me nearly 6-7 installs. Hopefully this last one with 2 partitions will work. It seems that this is a GPT / GUID EFI Partition VS MBR issue
