Solved Very odd connection problem on a Toshiba laptop

September 14, 2019 at 02:53:47
Specs: XL pro
Greetings

I hope someone can throw some light on a rather unusual problem withe a Toshiba L350 laptop:

Some time ago the laptop started freezing with a blank screens. At first it was only occasionally but became more frequent over the time to a point when it now does so within just a few minutes of starting on or restarting the laptop .
The screen turns mostly white or blue (NOT BSOD), sometimes black and very occasionally pinkish red.
There is no such problem when I run the laptop in the Safe Mode.
The odd thing is that it also runs perfectly on battery power only - the mains supply physically disconnected from the laptop. Within a few seconds of plugging the mains in, it freezes.
.
To reiterate:
Laptop OK in a Safe Mode (on battery and mains power connected)
Laptop OK in a Normal Mode on batter power only (with mains power disconnected)
Laptop only freezes when in a Normal Mode, with mains power connected to the laptop.
Removing the battery makes no difference.
(No problem with recharging the battery)

Kind regards
Mike

When I first read it I could not believe this would work, but it certainly does.

I now have a perfectly functional lap top!
Have been running it for a couple of hours now, will confirm - or otherwise - in a few days.

Thank you all for all your posts but in particular Johnw for his endless patience and dedication to help a total stranger.

I hope I am not counting my chickens to soon but for now at least,

Hi Johnw,

Thank you for your response.

The link: https://www.directupload.net/file/d...

Please note:
The laptop has been recently reformatted with Win 7 SPI. There are no other program installed not even antivirus so not connected to Internet.
The above link was obtained via WordPad then converted to PDF on another PC.

I hope you can work with this format otherwise let me know and I will install the necessary programs on the laptop.

Kind regards

On the Windows 10 laptop I'm using right now, the screen
brightness is somewhat less when on battery power than
when plugged into the AC / mains power. That is the default
set by Windows, I believe. It might be that something in your
video processor can no longer handle the full-strength signal
but is still able to handle the lower-strength signal when the
brightness is reduced.

This brightness adjustment is probably handled by a video
driver which is not used in Safe Mode. Perhaps Safe Mode
always uses a brightness less than 100%, and the driver turns
it up to 100%.

You can look in your power settings to try to confirm or disprove
that speculation. Then adjust the settings to see if that stops
the problem, at least for a while.

My guess is that it is either bad video hardware or a bad driver.
It could just be a bad connection between the video source and
the screen, though. Like a worn video ribbon cable that still
works as long as the signal level is not too high.

Hi Jeff,

Thank you for your thoughts.
I tried high performance and power save but it made no difference.

Regarding a bad video hardware or driver, there is no indication of any problem in the Device manager?

Kind regards

I would update all those drivers Mike, just do one at a time starting from the top & reboot if instructed to do so.

You should never use "driver finder or driver updater" software. Many of them are malware, contain malware, or link to questionable sites. The best way to update drivers is to do it manually, either by going to the computer manufacturer's site, or if you know your hardware, go to the hardware manufacturer's site.

According to notebookcheck.com, there are several models in the L350 series, each with a different CPU & graphics adapter. You would need to know the exact model number to know which drivers to download. It also appears your laptop is about 10 years old. It's very possible driver support has been discontinued, so your options might only be old drivers or generic Microsoft drivers. Regardless, if you've installed any type of driver finder program, uninstall it immediately & then do a full scan for viruses & malware.

https://www.notebookcheck.net/Toshi...

Here's a link to Toshiba's dynabook support site. If the info in parentheses is incorrect, just backspace it out & a list will appear in the menu. Select the correct model, enter your OS, then download the appropriate driver(s).

Did the problem start when you installed Windows 7 or were you having the same problem with the previous OS (which I assume was Vista)?

The reason for the clean install might also be helpful as it might point out hardware issues that were mistaken for software issues.

I was going to point out that you might not have updated the drivers after installing Windows 7.
I would install AV after updating drivers and connect to the internet at east long enough to catch up on Windows updates. You probably will have many updates on W7 so you might want to manually select say 20 at a time and install those, going back to repeat until all are in.

I also generally recommend manually getting drivers from the system manufacture sites rather than using a service BUT since JohnW recommends it, I am sure it is safe (at least this year).

Please note that when running under batteries only, there are things that run at a lower state to conserve battery life. Therefore it is possible that with things running on higher specs there are overheating or other issues. Run HWMonitor and list the various temperatures at idle, working, and heavy use like gaming. arun it on battery, in Safe Mode if you can, and normal AC operation if possible and post the results in a reply or as screen shots. Of course the driver update might be enough so try that first but temp evaluation is not a bad idea anyway.

You have to be a little bit crazy to keep you from going insane.

This is what I had in mind when I suggested looking at the power
settings. I used Windows 7 for years, but don't remember exactly
how they were arranged. In Windows 10 I go to Control Panel >
Power Options, then click on Change Plan Settings for whichever
plan is selected. There I get little sliders to Adjust plan brightness
(meaning adjust the brightness of the screen under that power plan)
when On battery and when Plugged in. My setting for On battery is
lower than the setting for Plugged in. I think they were that way by
default.

It could be something other than screen brightness, but the way it
affects your screen suggests that it might be brightness.

Your original post wasn't clear: Does the computer actually lock up,
or is it just that the screen stops working so you can't see anything?

I have been assuming the latter. If that assumption is wrong, and
the computer actually does lock up, then the problem is more likely
in software rather than in the video hardware.

Many thanks for all the posts.

Johnw,
Yes I have followed your instructions to the letter, alas it made no difference.

sluc,
Yes, this is the original charger and there is no problem recharging the battery.
Note that it also works perfectly in the Safe Mode.

DAVEINCAPS
The problem started (gradually) in Win 7 having run perfectly for a number of years.
But I also tried Win 10 when still able to do so with the same results.

Fingers,
I have tried a number of clean (reformatted) installs Win 10, Win 7 64 and 86 with all the up to date updates and drivers.
I will try the HWMonitor later today.

Jeff Root,
Re; "does the computer lock up", it's hard to say but it appears to just freeze, I have to hold down the start
button to shut it down.
Note that when I run it on battery, and then plug the mains in, it instantly reboots and then within few seconds of everything loaded, it just freezes.

Kind regards to you all

I'd still give updating the graphic drivers a try but since the problem spans different windows versions I doubt it's a driver problem. It might be a battery or charger issue as already mentioned. If not that then a screen or motherboard problem that likely would cost more to repair than the laptop is worth.

Next step Mike, just upload the 2 files as they appear on your desktop.

Please download Farbar Recovery Scan Tool and save it onto your Desktop. If your default download location is not the Desktop, drag it out of it's location onto the Desktop.
http://www.bleepingcomputer.com/dow...
If we have to run Farbar more than once, refer this SS.

Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.
Double-click to run it. When the tool opens click Yes to disclaimer.
Press Scan button.
It will make a log (FRST.txt) on the Desktop.
The first time the tool is run, it makes also another log (Addition.txt) on the Desktop.

Hi Johnw,

Slight problem, the laptop run out of battery power before the process completed. Subsequent attempt allows only a reduced functionality.
Will that be sufficient or should I reinstall the OS before I try again.?
Having reinstalled the OS, to avoid repetition of the above, should I run it in the safe mode?

Thanks

Ok, if you want go down that path & lose everything, this is what you do to get a clean install.

During the install, Delete all partitions, keep hitting Delete, until Delete & Format are greyed out.

You will be left with an Unallocated drive.

No other drives should be connected during the install.

Spanking clean Window 7 with all up to date security updates and drivers - still the same problem.

I may be worth baring in mind that this problem did not occur suddenly but over a few months of fairly moderate use of the laptop (see the opening post).

Another thing to bare in mind is, the freezing only occurs at the very final stages or just after booting up.

Kind regards

A very.... long shot and might be totally out in left field.

RAM?

How many sticks installed?

Meanwhile... with all power - removed main battery included - remove RAM modules and clean their edge connectors. Use a soft pencil style eraser - not anything abrasive.

Wipe the edges clean afterwards with alntless cloth (even a soft kleenex type tissue. Re-insert a module firmly into its slot. Then remove and wipe edge cooector again as above. Re-insert firmly and remove a second time. Wipe edge connector again and re-insert firmly again, and leave the module there. If two sticks do this with both sticks. But... initially leave only one stick in place after cleaning.

Restore power and see if things change (for the better) or not. If they don’t and you have a second stick, remove the first and insert the second - again do the swap with all power removed. Reboot etc. and see if things improve?

If things improve do with one stick but not both, then you know which stick is dubious, faulty; and ought to be replaced?

Failing RAM is often a cause of many odd effects during bootup, installation, and even a little after the system has booted ok.

Or, do this Ebay search daily:

What you're looking for is an L350 with the hard drive removed (since your old drive is OK) but otherwise working. (Sellers like to pull hard drives so nothing personal is passed along.) The ones showing there now are older ones that haven't sold because they're overpriced. You should be able to pick up a working L350 without the drive for around $50. I base that on having watched for a similar model--the C855--for several months on ebay.

Overheating:
runs at a fairly steady 45 C, well within the acceptable tolerance as I understand;

RAM cleaned and tested as suggested by trvlr:
while there was a slight difference in performance of the two sticks it had overall no effect on the problem in question;
Please note that memtest shows all clear. 

Things I noticed while performing these tests: 
Using a single stick at a time allows the screen up to 30 sec before freezing or rebooting.
Moving courser with a touch pad causes an almost immediate freeze or reboot, disabling touch pad makes no difference. No such problem using a mouse.
Remember that the problem occurs only in a Normal Mode when mains power (charger) is plugged in!

Any further suggestions will be appreciated but as a last resort I intend to re-seat the cooler on the processor.

Kindest regards to you all
Mike

"...as a last resort I intend to re-seat the cooler on the processor."
Please look at information here on cleaning and reapplying thermal compound for CPU heat sinks, they are not all the same processes so find your CPU on the site and look it over (same with all compound brands):
http://www.arcticsilver.com/methods...

What happens if you start it on battery, make sure it runs and then plug in the AC power? Does it still freeze right away? After a while? Not at all?

If you have a spare power 'brick' or know someone who has a similar model computer and same brand then try to test your laptop with it to see if it is the same problem or not. It is possible that the power brick is putting out voltage that is too high or not filtered enough (not 'clean power') and is actually causing the issues directly. This may especially be true if you are using an aftermarket 'cheaper' brand power brick. You may also be able to get a computer store to unwrap one new and let you prove that the new one 'works with your computer' and see in the store if that will solve your problem before spending money on a new one.

You have to be a little bit crazy to keep you from going insane.

Hi Fingers,

Thanks for your advise.

"What happens if you start it on battery, make sure it runs and then plug in the AC power? Does it still freeze right away? After a while? Not at all?"

It loads fully and operates perfectly on battery power but as soon as the mains power (brick) is plugged in, the laptop freezes.
It also loads and works perfectly on mains power in the Safe Mode.

Kind regards
Mike

Another test Mike, go into the Bios & reset to Defaults.

When I first read it I could not believe this would work, but it certainly does.

I now have a perfectly functional lap top!
Have been running it for a couple of hours now, will confirm - or otherwise - in a few days.

Thank you all for all your posts but in particular Johnw for his endless patience and dedication to help a total stranger.

I hope I am not counting my chickens to soon but for now at least,
Kindest regards and best wishes to you all!!!

This has to be on the weirdest problems I’ve seen in many a year. I wonder how the chap (Amjad) who came up with the resolution as posted worked it out?

Probably by googling trvlr, care to find the original poster?

It sounds like the method disables the CPU from automatically increasing its processing speed to its maximum which is detuned when on battery and not active when in safe mode. If this is the case then the BIOS setting for the CPU may be actually overclocked and unstable unless detuned when on battery.

If the fix works then enjoy it. I am just trying to 'read' what was done and the underlying issue from the instructions.

Indeed!

Fingers
" .... the BIOS setting for the CPU may be actually overclocked and unstable unless detuned when on battery."

Alas, there is no overclocking option on this machine and BIOS was set on Default ...
It would, indeed, be great to find out why it works in this sate. As Johnw suggests, maybe someone more savvy then myself could contact the originator of this solution?

I, myself, begun to increasingly suspect the processor, hence my intention to try resit the heat-sink.

Kindest regards

Possibly the CPU but possibly also a bad or glitched BIOS or the setting worked when new but overstress or weakness makes the settings unworkable in the long run.
