Odd Behaviour

I have an odd problem with the laptop :worried:

It is running very very slow

I have been trying to virus scan since this happened on Sunday. The machine is running at 100 percent constantly

It was mainly AVG running taking all of the power and stopping the processes only meant it restarted further down the list

A full scan takes about 4 hours normally but the PC shut down on it's own after twenty hours and still not finished

It takes about half an hour to power up and the firewall is disabled for a while on startup before re enabling itself

It can take five minuets or more to open a file and maybe 15 mins to start a programme.

Nothing is showing up and once and only once, after a restart it started normall yand did everthing at the correct speed

Yesterday I ran an AVG scan in Safe mode but it said it was clean. I ran a disc check and that took five hours and reported clean.

So today in case AVG was corrupted I un nstalled it and re intalled it....well tried but it would not re install and went into not responding...so I ended it.

A couple of hours later I noticed the AVG icon in the task bar and it said the all compants were up to date and working properly..yet it wouldn't install :wall:

BTW I have run CC several times and the registry function including after un installing AVG.

Then the odd thing

I am trying to use Photoshop and moving something using the arrow keys is painfully slow at a pixel a jerk with a pause and then by accident I find that if I hold the key down and rotate the laptop about 20 degrees anticlockwise the motion of the moving object suddenly spped up and whizzes along at the normal speed.

Rotate it back and slowtime.like now where I have to wait for the cursor at times on typing and it take a long time to scroll up and down this message in a serries of long pausing jerks :((

None of this makes any sense to me at all

I may be wrong Garry....but that sounds like a HDD fault....?

Can you hear the hard drive whirring when the laptop is busy..? Is the HDD light flashing...?

Either that or a virus that is not being detected by AVG...???

Hi Garry,

I would'nt like to say for definate on your circumstances but I had very similar behaviour from my last laptop due to something that AVG did'nt like or agree with on my system.

Not sure whether it was a virus or not but it caused the AV to act similar to what your describing.

The only way I managed to resolve it was to uninstall AVG and use another freeware AV program.

I used Comodo which is equally as good if not better than AVG.

It seemed to sort it. ;)

It the rotating thats odd

Anyway.just found out something

If I unplug the mains lead the machine runs normally

After wiggling t5he lead it is running OK at the moment

Perhaps there is a break and it was not giving fullpower??

Maybe rotating the machine, which was towards the lead was making a better contact??

Thanks anyway guys.........

Something eles I noticed but firgot to mention

The battery remained at 96 percent since yesterday morining.it was not charging.

A few minuets ago I sat back dawon and caught the lead which gave it quite a tug and now it is working properly on the mains as well and the bateery has already go uptp 99 percent.

Doesn't answer why AVG was running so much unless it was normal but the lower power meant a bigger slow up and usually it would have gone un noticed

Have you thought about using system restore to restore to a point before it went funny?

Hi Chris

It's a power cord problem

The mains lead is cutting on and off..if I take the lead out it's fine...plug it back in the machine slows right down. I can't use it on batteries as it only managed 59-64 percent overnight so there is not really enough power to charge it. I had it working well last night even on the power but after another power cutoff it's back to it's crawling with the mains plugged in :((

Could it be the power settings for running under battery? My laptop slows down the processor, granted not that much, and dims the screen to maximise the battery life. I've had to replace the mains adaptor twice in the 18 months I've had the laptop.

Hi Allan

Not settings :worried:

Been fine until now

If you touch the lead the mains power cuts off and the wiggling it give varying speed.

It can barely charge the battery with the machine shut down.....The power lead has visible damage :)

No matter what checks and tests made it shows power cord connection problems :((

I have had the power cutting for a week or too but this is an advancement on that problem although it didn't look like a power problem. Up until now I've not been able to replace it due to the fitting :'(

Garry not sure re AVG but you could try uninstalling it in safe mode then go for Avira free, Re power cord. Is it the bit from the plug to the box, if so a kettle lead will be a good replacement. If its the other side i.e. the lead from the power supply to the laptop, it would need cutting and then using a choc block connector as its only 12v its not a health and safety issue ;)
