Hi,

I am using a Sony VAIO Laptop which i bought 2.5 years back. It absolutely had no problem until 3 days back when i tried booting my laptop, it reached to the point where the password is typed for the user account. There was an error message that the Group Policy Client service has failed to logon and the laptop shut down. I surfed some sites and saw that there was a registry key which should have disappeared from my registries. So i booted my laptop in safe mode and created the registry key "GPSvcGroup". When I rebooted my laptop in the normal mode, it booted successfully but when i tried to open explorer, another emssage popped up "The media is write protected" followed by a shut down.i went again googling and found that i would need to create another registry key "StorageDevicePolicies" and i did. when i booted the laptop normally after that, the laptop shut down with no error notification after 20 minutes. continued booting the laptop resulted in the laptp shutting down in even lesser time.

I kept the laptop in BIOS mode and it shut down after 40 mins. I opened the laptop to see if evryting was okay with the fan and i cleaned as much as possible although i have never unscrewed and take the complete exhaust fan out.

I cant afford to reformat the HDD coz i am currently recoverin some data for some personal purposes. is there anything anyone could help or advice?

I also removed the HDD and plugged into my friend's laptop, ran an antivirus and quarantined 2 viruses. The tech support guy mentioned that the program files also didnt have a few .exe files which could potentially be removed by exe virus.
I have no clue though.

If you left the Laptop just in the BIOS (not in Windows or any Operating System) then it's possible you may have a hardware issue. Laptops powering down randomly are usually due to something inside overheating (video chip, CPU, etc). Make sure the vents are clean and not clogged by dust, hair or anything else.

If you confirm that even in the BIOS it shuts down, then the problem is most likely hardware. If you leave it in the BIOS and it does not behave the same way, try a different operating system such as an Ubuntu or CentOS Live CD. The OS runs directly off a CD or Flash Drive and loads proper drivers for you to browse and do most things. This is always a good test to rule out Windows as being the problem.

Another good "rule out Windows OS" 'live CD' is self-booting UBCD. It also includes a number of easy-to-run tests that can check your hardware (e.g. CPU, RAM, HDDs, motherboard, etc.) and provide detailed status/info about your system hardware.
http://www.ultimatebootcd.com/
http://majorgeeks.com/Ultimate_Boot_CD_d4981.html

A distinct advantage of downloading and using UBCD, a diagnostics oriented tool, is that it is a LOT easier and much less time-consuming than trying to download and install a complete OS such as Ubuntu or CentOS.

If you aren't familiar with the concept of booting from a 'Live CD', you can usually easily change BIOS settings or UEFI to select such that computer boots from the CD/DVD/Blu-ray drive before it tries to boot from any HDD. This boots the OS that is installed on the CD (e.g. UBCD's OS, a linux derivative) instead of your HDD. In some cases, a given linux-derived OS may be unable to boot a proprietary laptop/notebook computer. However, this is becoming less of a problem over time as the various 'live CD' packages mature.


edit to add:
I should have pointed out that UBCD is freeware/donateware. It's quite easy to use. I use it mostly to self-boot and run "memtest86+" but as I said earlier it does have other useful diagnostics and utilities. Also, I've added a pointer to majorgeeks.com as an alternative download site.

Never heard of the UBCD. Seems interesting and very useful for the advanced user. I may give it a shot in the future.

Like Joshua, I normally use a Ubuntu live CD. But, not only do I use it to rule out possible Windows issues, I also use it to transfer files between hard drives. Another advantage the Live CD has is that it has a pretty GUI, and like Joshua said, it loads drivers for most devices so 9 times out of 10 you are even able to access the internet with just a Live CD.

Hello,

May I know what OS you are using? As per my knowledge XP CDs come with a repair option. It will ask for repair when we insert the CD in to the drive. They are two options on is fresh installation and the second is repair.

So, if repair option is clicked then the OS files which are missing will get replaced automatically and all your data will be intact. I had a similar issue long back and so have a bit of knowledge in this stuff, as I was using XP at that time.

The process is simple and you only need to insert the key. But the fact is that you need to adjust the bios settings and set first boot device as DVD ROM.

If it is a Windows 7 OS, then it is even simpler. As in such cases, the OS identifies the problem itself and goes for repair.

It also replaces missing files in this process including registry keys.

Hope, this helps....thanks!

Thanks, Joshua. I will try that. As long as I dont lose any data. I am okay to do anything. I opened the laptop and cleaned the heat sink and the exhaust fan. As u rightly mentioned, the exhaust fan has potentially a problem, i think. I kept the laptop on a laptop cooler table and it seemed to stay on the BIOS mode for more than 2.5 hours which is a good sign.
I will try the Ubuntu LiveCD that you suggested. Can i run any antivirus through that to check for viruses?

I have been going through some real hard times now. I tried copying the data from the hard disk by acccessing it as an external HDD from my friend's laptop and copied most of the stuff to my external portable drive. But i didnt realise it was lying on the bed and by mistake i pressed it with my elbow. Its now not recognised if i plug into the laptop. :( I have lost all the data i copied. I am trying to recover the files using a recovery software from my HDD as much as I can.

Thanks Joshua and John.

Hi Naveen
The OS i am currently using is Windows 7.

Hello,

Sorry to hear about your plight. But i believe that your windows 7 OS, if had any files missing, would have gone for a repair and quick update by now. I think the problem is somewhere in your PC hardware. The improper shut down may also be due to some recent hardware change. It can be a recent connection to a mobile device, camera or IPod. Also malware presence can also lead to such consequences if the malware has crept into the kernel of the Operating System.

My advice is to access the hard drive from a different Windows 7 PC as an external drive. If the OS has problems then those problems will get nullified by the presence of another OS in the background.....hope this works for you!

Looks like you've addressed the potential hardware problem (over-heating) Joshua pointed out above. This may be a completely separate issue with the HDD / virus infection you mentioned. Though sometimes manufacturers do rely on software drivers (installed in the HDD), in addition to the BIOS for proper running of their hardware.

Vinith B said:

The answer is Yes. But with your HDD's out, there's no point of doing so.

Ay yay yay...sorry to hear that. Usually those drives are pretty hard to break, but mishaps happens. If you haven't format your original HDD, you can always copy the files again.

I've been trying to make a point very similar to Dr. paz.

There is no point on even troubleshooting the OS, search for viruses, etc, if just in the BIOS the laptop is powering off. The error is completely OS independent, so if you don't fix the hardware issue, it can be Windows 95, 98. Vista, 7, or 8, and you will still get the random powering down problem.

Fix that 1st, then move on to the next thing. Can't start running if you can't walk properly :)

.
Something relatively easy and quick to do is physically check the RAM. On older computers the RAM connections may have corroded slightly, shifted, etc.

Try reseating the RAM module(s) then test. If the problem continues, try testing the RAM modules one at a time (if more than one) using a utility like "memtest86+". You may find a particular RAM module is causing the failure.

CRITICAL: Follow your user manual instructions for handling and uninstalling/installing the RAM module(s). (e.g. make sure you practice appropriate power and ESD protocols while doing so or you can permanently damage your computer)

UBCD can exercise your laptop and specifically test various elements. "Memtest86+" (included in UBCD) is good for testing RAM over long periods of time. It can be used to make sure your system warms up and may help discover problems aggravated by normal or excessive heat in the system.
