G770 laptop startup problem

After 5+ years, laptop will not boot.  Press On and get Lenovo image, but then goes to flashing cursor on upper left, with no further boot up.  Have disconnected power, removed battery and held ON button to dissipate the gremlims, reattached power (but not battery) but still same result when restarting. Have tried this many and several times.   I have a 64-bit Windows 7 Repair disk for Lenovo that I burned once upon a time.  Put that in, it spins for a while at startup but nothing happens except the same flashing cursor.  Have tried pushing all the F-buttons at startup and same result.  Have also tried turning on by pushing the little (NOVO?) button next to the ON button but nothing happens.  Any ideas?

Re: G770 laptop startup problem

Sounds like the hard disk drive is causing issues. Usually if the system cannot read the first few tracks on the disk it will lock up the start up procedure and cause issues similar to what you are experiencing. Also - the age of the notebook would also suggest a hard disk failure and require the same fix, a new hard disk drive. Purchase one that matches the specifications of the current drive, or one that is bigger based on the specifications (Sata, Speed, connections) and then use your recovery disks to bring the system back to "as built" standards.

Good luck.

Re: G770 laptop startup problem

Hi AZSteve,

 

Welcome to the Community Forums.

 

If you have any data to back up from the drive then perhaps manually removing the drive and placing it on an external harddrive enclosure to connect to another machine can help. This would allow you to also check if the drive is still accessible.

 

You can also try booting on a diagnostic image from here to run a test. 

I hope the Windows repair disk you have created is bootable and can install Windows 7 back , else you would need to purchase a recovery media from Lenovo.

 

Update us how it goes best for you.

 

Regards

Re: G770 laptop startup problem

Thansk for the response.

 

If the Recovery disk is bootable, wouldn't it boot up when I put it in the disk drive before "startup"?  I had put it in, turned the computer off, turned it on, and when the Lenovo logo appeared the disk drive also started.  It ran for about 15 seconds (during the blinking cursor phase) then stopped.  If it was indeed bootable, wouldn't it have started something on the computer even if the boot section of the HD was no good?

Re: G770 laptop startup problem

Hi AZSteve,

 

Greetings.

 

At this point, we cannot say that the recovery media is bootable with the same symptom.

Did you try using the bootable diagnostics yet?

 

Upon restart, try tapping on F12 for the boot manager and check if you would see the option for the created diagnostics media.

You may also try the recovery disc with the F12.

 

Update us how it goes.

 

Regards

Re: G770 laptop startup problem

I know the CD drive spins on startup, so based on "linux-bootable-cd-41308857.txt" I burned the "linux-bootable-cd-41308857.iso" to a CD using a media tool, then inserted the CD into the CD drive of the Lenovo and restarted that computer.

 

The CD drive spun for about 15 seconds but nothing happened.  And again, F12 did nothing.

Re: G770 laptop startup problem

Hi AZSteve,

 

I am suspecting primary boot in the BIOS had a fast boot on the default HDD.

Try to turn off the machine and use the novo key to turn it on.

 

It should give the Novo Menu to check the BIOS boot priority, setting the boot mode to legacy would allow you to change boot priority to the CD drive or usb media.

 

If that would not work, then isolate further on the issue removing the harddrive.

Using the Novo button to turn back on and see if the BIOS is accessible.

 

Regards

Hi  AZSteve,

 

Remove the harddrive as this would isolate Software and harddrive issue.

The machine should turn on using the Novo Menu and check if the BIOS is responsive.

Re: G770 laptop startup problem

So I took your second suggestion and removed the HD after finding a video online on how to do that.  Replaced cover and pressed Novo button but nothing happened.  Pressed ON button it said it couldn't anything bootable. (Hey, it's finally telling me something!)  Put in the Lenovo Diagnostics CD I had created earlier per instructions. And that booted up!

 

All checks passed, so it must be the HD.

 

I can now set the boot order, but the choices are

SATA ODD    :    PLDS DVD-RW DS8A8SH

NETWORK BOOT   :   LEGACY PCI DEVICE

 

I have to choose one line or the other to be first.  It seems like I would want to put the DVD first and SATA ODD second so I could boot from the CD but then still be able to go in and look at the HD.  And then save files to an external HD.  Or maybe run a CHKDSK on it - if the boot sectors were bad would it put them in an acceptable place so I could then still boot from the existing HD.

 

So if I put the HD back in it will probably try to boot from that again and freeze.  Any ideas on that?

 

I can choose to repair something, but without the HD in there is nothing to repair.

 

And it's not obvious if the repair disk really has everything to install Win 7.

 

So the question now is, do we buy a new computer and try to rescue the files off the bad HD, or do we buy a new HD for the Lenovo and maybe have to buy an OS to install too.  The Lenovo was manufactured 12/2012 and we probably bought it a several months later on closeout (it was the last one in Phoenix).  We can get a new HP 17.3" with an i5 processor for $480 on sale (reg price $620) at Staples.
