Author Topic: Power failure during repair: Laptop not booting (Read 51712 times)

amf · « **on:** January 29, 2017, 06:03:05 am »

I ran repairs on my Lenovo G510. As recommended I took the battery out, disconnected the power cord and pressed the power button a few times. I noticed that the power cord wasn't plugged in as the first of the repair tasks was running, and plugged it in and left to do some shopping. While I was out we had a power failure as a result of a severe storm. When the power supply was restored the notebook wouldn't boot.

The Windows Autorepair failed - and I can't get the notebook to reboot through any of the standard Lenovo recovery tools.

Please help!!!!

I assume you didn't put the battery back in after the cold boot ?

Do any lights come on when using it just on battery ?

I did return the battery.
The lights come on, and options to reset the notebook come on. It would be my very last resort. I have removed the hard drive to copy work I have to complete tonight (South African time).

What are the options that you get ?

Hi

I had a huge workload so just took out the hard drive to get access to my files.

My workload has now reduced to such an extent that I can attempt to get the Lenovo up and running again.

I tried to get it to boot from a restore DVD, but guess I'm too much of a noob to to do it.

By starting the notebook with the restore button I get the following options:
Normal Startup
Bios Setup
Boot Menu
System recovery.

Your assistance and patience is appreciated!

See what Normal Startup gets you.

It just comes up with the Lenovo logo and then hangs

You could try System recovery and the Startup Repair, running that up to three times if it at first fails.

If it continues to report that it is unable to fix then in System recovery select Command Prompt and enter bcdedit |find "osdevice" then enter chkdsk x: /f where x=the partition letter to see what that reports.

That is a Pipe symbol before find and is the uppercase of \

It's unusual for an outage to cause a boot problem when a battery is installed to continue the power supply.

It's possible prior to the outage their was a surge which could have damaged hardware, but see what the chkdsk x: /f reports and if there are any KBs in bad sectors.

No Go so far

Which version of Windows are you using ?

amf · « **Reply #10 on:** February 08, 2017, 08:32:19 am »

10, updated a day or so before the mishap

Boggin · « **Reply #11 on:** February 08, 2017, 08:43:30 am »

Do you have a Win 10 install disk ?

If not and you have access to another machine with the same architecture (32 0r 64 bit) as yours, you can download the ISO from https://www.microsoft.com/en-gb/software-download/windows10 by hitting the Download tool now button after reading how to create installation media.

Got both the USB and DVD recovery diskd, neither seems to resolve the issue, unless the boot sequence is wrong

Boggin · « **Reply #13 on:** February 08, 2017, 08:54:29 am »

This is the problem with Win 10 - unless you have your machine set to boot from DVD and USB before the upgrade, then it's usually too late to change when things go bad.

You could try tapping F12 as you switch on but it may ignore that.

amf · « **Reply #14 on:** February 08, 2017, 08:55:54 am »

Will try.
Any other suggestion?

Boggin · « **Reply #15 on:** February 08, 2017, 09:09:09 am »

I'm not sure if this will work on yours but switching the machine on and off three times can get you into the recovery mode, but you would switch off as soon as you see the Win 10 logo and then you would see Preparing Automatic Repair and then Diagnosing your PC

Trying this on another upgrade Win 10 laptop, that took me to Your PC did not start correctly and to choose between Restart and Advanced options.

Selecting Advanced options gave me the Troubleshoot option/Advanced options

If you can get to there and select Command Prompt, enter bootrec.exe /rebuildbcd to see what it reports.

Ignored it like people do with stop signs around here

Boggin · « **Reply #17 on:** February 08, 2017, 09:15:25 am »

Have you tried what I've suggested in my last post ?

amf · « **Reply #18 on:** February 08, 2017, 09:28:41 am »

Changed the boot sequence to start with the USB. at least some action below the Lenovo logo

Boggin · « **Reply #19 on:** February 08, 2017, 09:41:27 am »

Well that's good news.

Can you navigate to the Command Prompt to enter that bootrec.exe cmd ?

amf · « **Reply #20 on:** February 08, 2017, 09:43:34 am »

Little wheel below Lenovo logo still running, hope and pray for a good result

Boggin · « **Reply #21 on:** February 08, 2017, 09:49:05 am »

My Win 10 ISO is on a DVD and when I boot up with it I get a prompt to press any key to boot from CD/DVD.

I've never booted up my Win 10 with an USB so don't know if you should get the same prompt, but hang in there as something is happening.

amf · « **Reply #22 on:** February 08, 2017, 09:51:33 am »

Never thought I'd be as happy to see dots running in na circle, but getting frustrated, something should happen soon

Boggin · « **Reply #23 on:** February 08, 2017, 09:58:34 am »

Win 10 can sometimes repair itself and the busy can seem never ending, but you could do a power shutdown and try again where you could get a message on the screen.

I'd give it a bit longer.

I'm going to have to shoot off for a while but will be back later.
