Laptop Hangs on warm reboot

July 4, 2013 at 07:43:50
Specs: Windows any version, 2.2Ghz/2Gb
My notebook hangs on warm reboot only. Cold reboot works normally.
Anyone had a similar issue?
Any ideas what could be the reason for this?

At what point does it hang, during shutdown or during restart? It could be you have a lot of crap loading in the background at startup, but it seems it would also hang or boot very slowly on a cold boot too. We need a more detailed description & it might help to post the make/model of your laptop.

Hi polypoly,

Please let me know the system model and the operating system installed on the system.

Also, let me know if you have made any hardware change recently.

Meanwhile, refer to the link mentioned below:

It hangs at the point where you can enter the Bios, a few seconds after the power kicks in.
This is an Acer Aspire AMD notebook.
I have Xp, win7 and Win8 installed. All running fine, no crap loading and booting up fine fom a cold boot! It does not matter what Os I use, even from Live CD's it won't warm reboot.
I flashed the Bios but that didn't help.
The DVD player is not working.
Made no changes in the hardware.

It sounds like your notebook is overheating. It may be hot when you shutdown and once the fans stop the temperature can actually go up a little.

I suggest you get canned compressed air from the office supply or computer store, and blow out the vents on the bottom.

You can also download a utility to monitor the temperatures in real time while using the computer. Get the free version of HWMonitor from the link below. Post the system and CPU temperatures after using the computer for a while.

Hi thanks for your reply. The temperature seems not to be the problem. It happens also when the computer hasn't been running for a whole day. Just booting from a USB Live OS and warm rebooting immediately crashes it. Pressing CTRL ALT DEL immediately after booting the comp would make it reboot and hang.
I checked temperatures awhile ago and they where fine.

Is this a hardware problem? It's definitely OS independent, coz it happens with any OS (Win and Linux, including repair disks)
Read somewhere that taking out CMOS battery and press power button for a few seconds can be a solution??? (releasing static)
Thanks

Then try running Memtest86+ to determine if the memory is faulty. If your memory is all removable then try removing it, rubbing the contacts with an eraser and snapping each module in and out 4 or 5 times. This will burnish the contacts.

Cold boot issues can be caused by poor conductivity. When parts warm up they make better contact. With a laptop there aren't many connections that you can fiddle with.

Did you ever drop the laptop?

You could also try running a hard drive diagnostic (fitness test).

@ Othehill: I've done Memtest but never finished the job! Will do this time, over night.
I did drop the laptop 6 months ago but not sure if warm boot problems started after that.
Have done HD diagnostics test (using HDDSCAN 3.3) and the hd was in very good shape.

@Othehill Drive is ok, only a few bad clusters and good reading speeds! (hdscan)
Anything else you can think off?

Hi polypoly,

As you mentioned that test on hard drive and memory have passed, it seems to be an issue with the system board. Also, you have mentioned that the system is not heating up.

If the drive has ANY bad clusters then the drive may be failing. New hard drives are made with spare space to replace any bad clusters. This is done without any user input. Once you see bad clusters, the reserved space may have been used up already. That would indicate more than just a few bad clusters.

Did you run the manufacturers' fitness test?

I understand it has some bad clusters but would that affect the reboot procedure?
As I mentioned before, it does this booting Linux from USB stick too!
@OThehill I have not run the manufacturers' fitness test yet. THis is a replacement HD already, first one failed big time!

If it is the mainboard, are there any connectors I should check??

If you replaced the hard drive once already, under warranty, then chances are you received a reconditioned drive.

Possible that the connections to the drive are loose.

@Othehill I would have had lots of disk errors in event viewer as was the case with my previous HD, right? Just to be sure I will check it.
What bothers me is the fact that everything works fine apart from the warm reboot.

The bad clusters are replaced without notice until there are no more spares available. Then you see the notices for bad clusters.

This may not be the reason for the warm boot issue, but you should still look into it.

Should I claim it again? It's 3 years warranty, but I guess that's almost over now!
Any other ideas for the warm reboot issue?

Hi polypoly,

If the system is in warranty, I would suggest you to get the hard drive and the system board replaced.

If it is not in warranty, replace the hard drive to isolate the issue.

If the seek time when warm booting is less than when cold booting, the drive may not be configured on a warm boot. That is one of the parameters checked by the fitness test.

Usually, a bad solder joint will cause problems on a cold boot. After the components warm up the joint may be more conductive.

The only things I can think of that might change with a warm boot are: Power supply could be going bad, or the capacitors on the motherboard could be failing.

Not much you can check with the power supply, but you can look at the motherboard for bulging or leaking capacitors. See the link below to learn what you are looking for.

Thanks for the nice info!

@Othehill: What program do you suggest for checking the seek time? Any tools for reconfiguring the HD?
Also I can't do a warm boot so how can I compare the seek times?


I've done the short tests with Seatools, all passed.
And here is a SMART report,

If the seek time was outside the specs then Seatools would have noted that.

Did you look at the motherboard for bad capacitors?

Another issue occurred, I wonder if this is related. It sure happened before. Hers is what happened:

1 Hibernated the laptop on battery power (dangerously low, possible that the process did not complete)
2 When turning on, only black screen, even no F2 F12 options
3 Turned it off and restarted
4 F2 F12 showed so choose to enter Bios
5 34 seconds past
6 Bios didn't show a HDD for the IDE 0 entry
7 rebooted but had to shut power down first (as usual)
8 black screen again
9 shut down and booted from USB install disk (win8) (This is my way to deal with this issue) Shut down the laptop at the first occasion to exit the setup (so before installing)
10 rebooted and the bootmananager showed, everything back to normal. (showed the screen where i could choose between normal mode, safe modes etc

Any ideas what caused this and how to boot normally without having to use my usb stick first?

My apologies about the capacitors. This thread originated on July 4th and I should have looked back. Don't attempt to open the case for that purpose.

If the hard drive is not being configured in the BIOS all the time then that would indicate some type of hardware problem.

Post the model number of your notebook.
