Sony :: VGN-Z820D Locks Up Intermittently
Jan 27, 2010
My VGN-Z820D locks up intermittently. This happens every few days and always about 5 minutes after resuming from sleep. It seems to happen whenever as program is launched.
You double click and the circle starts spinning but nothing happens. The spinning circle can be moved around but that's it. CTL-ALT-DEL does nothing. You have to turn off the laptop.
I have tried keeping the task manager open when it happens but noithing happens in the manager. No cpu activity, no changing of processes, nothing.
This is windows 7 pro. I have removed almost all of the sony bloatware, step by step and nothing changes. I have the following items left
VAIO Care, COntrol Center, DVD Menu, Event Service, OOBE and Startup assistant, and origninal function settings.
There is nothing in the event logs at all, no errors or warnings.
All of the drivers are up to date.
There is never a problem during use if it doesn't fail at around 5 minutes. This pretty well rules out a hardware failure. I can go for days without this happening but then it happens again.

Sometimes, for example, when I open a new tab in Google Chrome (not beta) and enter a web site, or click a link etc. the notebook locks up. This sometimes happens with other softwares, or just Windows softwares, or browsing files randomly.
When it locks up, hard-drive is flashing and hard-drive activity not stopping. I am able to move the cursor, but I cannot click anywhere. Even I cannot open task manager, the ctrl-alt-del also doesn't work. I have to push the power button to reset the notebook.
Notebook's specifications are:
OS Version 6.1.7600 (Win7 64-bit RTM)
Mobile DualCore Intel Core 2 Duo P8600, 2400 MHz (9 x 267)

I've had my M17x since last September and while I've come to accept the fact that it locks up on occassion, lately it's been getting rather ridiculous. Today alone I have had to do 6 forced reboots because of lock ups. It's pretty much a given that the machine will completely lock up around 100% CPU usage, but outside of that it can just happen randomly as well. This is particularily annoying if I'm doing a task that does put some stress on the CPU, there's maybe a slim chance I'll get to actually finish it before it all freezes.

I just get to a screen showing the HP logo...the computer tries to self diagnose but never gets anywhere. Just stays locked. I've had this computer for almost a year with zero issue. Suddenly this.

I recently updated my bios on my R7-571 and it has caused me great woe. Â My computer will lock hard between 3 min and 3:30 min after bootup if I don't disable the WIndows Managment INstrumentation service. Â THis of course caused other problems on services that depend on that like LogMeIn. Â I need a solution to this. Â Either a way to downgrade to an earlier bios which I don't think is possible without a version of the bios updater that will support this, or a newer bios that addresses this issue.

I've been playing BF2142 at max settings since I got the new notebook. Then suddenly I can't play it anymore... It freezes and goes black after 5-15 seconds of playing, leaving ctrl-alt-delete as only option.
At the same time, I can play Quake: Enemy Territory (which seem to demand alot more from the gpu) just fine (on somewhat lower settings though, but never freezes)
I'm using the infamous "hacked" performance drivers, can't remember the name.

My Split X2 occasionally locks on the blue HP logo during startup. Usually a hard restart will work with no other issues.  A few times, including today, the hard restart does not work and it continues to lock on the logo screen. I hard restarted around ten times today before it finally fully booted.

Just bought a new HP ENVY m6 Notebook PC. CyberLink YouCam 5 cam pre-installed. I can open the software and it appears to run fine but when I try to access the settings the computer freezes and locks up. I end up having to hold down the power button to force a shutdown.

HP g7-1150us .....Problem started after replacement of the touch pad/mouse cover. It initially did not power on. I plugged in AC in case the battery was dead and tried again.
Â
Then it started the continual blinking. I tried the hard reset, hitting ESC upon powerup but had no luck. The hard drive is spinning, but not seeking.
Â
I removed the new panel, and put the old one back in and there was no change. I'm confident that I did get all the cables & connectors in correctly.
Â
I thought I may have killed one of the memory sticks, so I tried installing just one. I do not get any of the 6 different blink sequences, it blinks slowly about 1/sec continuously.

my computer screen has either been doing a brief flash or weird movement and then locks itself up. Everything is running but the screen, which is frozen in place (the mouse icon is also frozen). I was wondering if anyone had suggestions on how to fix this. I thought it was an overheating problem, but it's sitting at 53•C and still does it. It started doing this when I was playing WoW (only while playing), but that was 3-4 weeks ago and until now the computer worked fine.
It will also no longer restart itself; it goes through the shut down process but then basically powers off as if I just turned it off versus shutting down turned off (this laptop has distinctive sounds for both which is how I can tell). Normally I can wait a minute or two and then turn it back on and it boots up (if I try to turn it on right after it cuts off after a second). Now however, it gets to the first logo then cuts off. I have used compressed air to blow in the vents to get rid of dust if that might be a factor.

Dell XPS L501X USB Ports not working properly. My USB 2 port work intermittently and my USB 3 port doesn't seem to work at all.
In November I installed Windows 8 Pro 64 bit on a new Crucial CRM4256SSD 256GB m4 Solid State Drive. Everything seems to be working except the USB Ports. I know my laptop is an unsupported Windows 8 system. What USB drivers I need to install to get them working correctly.

My 15Z touchscreen works intermittently. It will be working just fine, then it starts to take a second to respond. Then it stops responding at all. Then it starts working again. I cannot identify any pattern to it.Â

I have an Inspiron 15R 5521 that intermittently restarts at various times. Â It doesn't seem to matter whether I am working in an MS Office Application or Firefox, IE, Chrome at least as far as noticing a pattern. Â
I have tried to run the diagnostic tests on the Dell Support site numerous times and keep getting the message "A problem has been detected, please try again" at the third step in the Diagnostic test process, 'Installing my Dell client'. Â

There is a recurring problem where the computer ceases to recognize the existence of the wireless adapter. It doesn't matter if the computer is running 8, or 8.1, nor if the computer is fully Updated. This seems to be a hardware problem or some sort of electrical short, not a driver problem. I have done a bit of research over the last four months or so (when the problem first started happening), and the problem I am experiencing is most likely caused by either a faulty card, or a card that is loose from its socket on the motherboard, and not by a driver/hardware discrepancy.The strange part is the intermittent nature of the computer's recognition of the device. Stranger still is that despite what appears to be a hardware problem, I have usually been able to fix it, either by:
Â
Uninstalling then reinstalling the device's drivers,Restoring the computer to a previous point,Reformatting the computer using the built in Windows 8 feature, and/or Removing certain Windows Updates in reverse chronological order (until the integrated WiFi device is recognized).
Â
Last night, the problem happened again. It was maybe the 4th or 5th time overall, and the 2nd time I was forced to "hard reformat" in an attempt to fix the problem. Until just a few minutes ago, when I partially deconstructed then reconstructed the device, the "hard reformat" method didn't fix the WiFi. After the "hard reformat" didn't work, Upon turning the computer back on, it recognized the wireless adapter, I connected to the network successfully, and here I am now, documenting what happened.
Â
I essentially did nothing significant to the device, and now the wireless adapter is recognized. Why?
Â
All that being said, I believe I have narrowed down the cause of the problem, at least in my case. I believe there is some sort of electrical short issue. The short is caused by one (or perhaps both) of the following:
Â
Assuming the physical location of the wireless adapter is next to the location of the port for the AC adapter, I think the AC adapter, when moved or jiggled by a hand, somehow negatively interferes with the wireless adapter, causing it to fail.Shutting the lid of the computer, perhaps when combined with the above, and/or under other conditions (something having to do with power settings?, something having to do with the state of the network when the lid is shut?), causes the network adapter to fail.Something very similar used to happen on an old Dell notebook I had, as well as on a CR-48, towards the end of their lives. That is, in order for the internet to work, I had to have the AC adapter at certain angle when it was plugged into the computer. Otherwise the wireless connection would drop. It seems like there's a connection there (pun intended), but perhaps not?

Dell Latitude E6400 ATG mouse pad works intermittently. It will work then stop and I have to use the keyboard nub. Then it will work. Then it will not work and it will drift to one corner. If I press on either side of the mousepad wrist rest area it will drift faster.Â
This is why I think it is a hardware issue.
I have updated with the most recent driver several times and it does not correct the problem. Driver is dated 1/13/2011

I know about the DC Jack problem the 5150 has and I don't think this has that it works great with the AC adapter plugged in.
I have already tryed another battery and same results. I ordered a new AC adapter and I am (albeit impatiently) waiting for the arrival. So in the meanwhile I thought I'd ask here if anyone has any ideas (And if the AC adapter doesn't work)????
I have already done a search and the only relevant item I found was something about the LVC14A chip issue and was wondering if it could be that?

The sound is failing intermittently on my T430.
Â
Closing then opening the lid to enter and return from hibernation sometimes restores sound. When this does not work restarting the machine usually restores sound. But the sound fails again after an indeterminate period.
Â
Opening Ubuntu Linux in Virtualbox now displays the message "Some audio devices (PCM_in, PCM-mic) could not be opened".

I have a brand new ProBook 430 G2 (SKU # G6W35EA#ABB) with Windows 8.1, fully updated. I find that every 10-15 minutes, the left button on the trackpad becomes unresponsive. The trackpad still moves the mouse pointer and the right button continues to work, but the left button does not react. This lasts for several minutes, perhaps 3-4. Then the left button resumes working as if nothing had happened. Since the button resumes working, I suspect it is more likely to be a software issue with the driver or Windows 8.1.
Â
I have Synaptics TouchPad driver version 18.1.8.1, the current version of the driver.
I have Windows 8.1 version 6.3.9600.Â
I have Bios version HP M74 version 1.03 (07/07/2014)

Running on Windows 7. I've read similar problems that others have posted, which is the monitor goes black during bootup. My machine boots fine, but every few minutes the monitor goes black / dies - no backlight.
Â
This lasts a minute or so, then the display go back to normal. Then it goes black again. Then it goes back to normal. It's not sleeping, the HDD keeps on spinning.
Â
I've checked the graphics driver - no update available. I reinstalled it anyway. The built in lenovo utility -thinkvantage- is of no support.
Â
At this stage I'm wondering about the integrity of the motherboard.

I have had my Inspiron 7347 for a few days. When operating on the battery, the touchpad exhibits some quirks that make this P:C extremely hard to use as a portable laptop.
The mouse on the touchpad hangs up intermittently, sometimes for several seconds. This erratic behavior makes using the mouse terribly difficult.
When scrolling using the mouse on a vertical scroll bar, the right click menu for the desktop keeps popping up.  I must move the mouse away from the scroll bar, left click to get rid of the right click menu, and return the mouse to the scroll bar. Sometimes this behavior is constant when scrolling through a long page, making it impossible to use the mouse to scroll.

I just received my Inspiron 15 5547 computer 2 days ago and one thing I noticed is that intermittently the touchscreen freezes for 3-10 seconds at a time, when this happens the computer is not frozen, I can still move the cursor with the touch pad or with a Bluetooth mouse.
I have contacted tech support and they advised to give it a few days to see if it continues to happen and confirm that the computer in fact does not freeze. I am wondering if this is normal for this model? Or if this is an actual hardware issue with my computer.
I also am wondering about getting a stylus to use on the screen for drawing. If I get one like the Adonit Jot or one like used for a Samsung Galaxy Note III would that work? Would it cause any damage to the screen?

I have been having issues with audio on my G500. One moment it works and the next it doesn't. I don't quite know what can be the issue. I have tried multiple browsers to see if that is the issue and it has not made a difference. I am running Windows 8.0, 64 bit operating system if that makes a difference. This laptop is not even a year old.
