G550 Freezes Due To Hardware Faults?

Hi Guys, I would appreciate your opinion on this, I have a Lenovo G550 (Model 2958) which regularly freezes, the symptoms are this:
* No blue screen or any failure warning.
* Mouse will not move, and all buttons are non-responsive (requiring forced power off as only option).
* Is not specific to any specific software, can happen with office, or firefox, or no windows open.
* Can happen within 5-10 minutes of start up, or even after hours of functional working.
* Usually happens on warmer days (above 20 degrees C).
The laptop's spec is this:
Bios update 44 (Release Date 2010-04-30) (latest)
2.2Ghz Core 2 Duo,
4GB (DDR3 - 1066Hz) RAM,
500GB HDD
NVIDIA GeForce G210M (512MB) (latest drivers)
Windows 7 Home Premium
I have reinstalled several times and the problem still exists, which leads me to believe it is a hardware issue, most probably something heating up too much perhaps.
The laptop is raised up and plenty of air gets to every surface.
I bought it in February 2010, so the warranty is OK, what will Lenovo likely do regarding: fixing it, can they replace it? Will I have to pay for any hardware fix?
Thanks for your advice :-)

Call customer service. Your laptop needs technical assistance.

I purchased a Genuine Apple iPhone Lightening Cable from the Phone Shop I got my iPhone from after the one I got with my phone broke, it has broke due to no fault of my own and it's the 4th one I have had, will Apple replace the cable for free or not?

The original cable has the iPhone's 12 month warranty and any items purchase as accessories also have a 12 month warranty

I have recently had my hard drive replaced due to a fault whilst in Germany working. Happy with the replacement, however when i go to log on as a user that screen is in German? Any idea how to change the language?

Laptop Toshiba P50-A-K9M often freezes due to unknown reason

Hi,
My Toshiba P50-A-K9M constantly freezes due to unknown reason. My OS is Windows 7 64-bit.
Initially I thought that it was due to overheating. However, when I enabled CPU temperature monitor I noticed that freezes happen even if the temperature is relatively low (39%).
My second guess was about memory. But Windows memory diagnostics passed without any problems.
I can't confirm it but I've a feeling that it happens on CPU intensive tasks but it's not linked to particular program.
I had freezes while compiling an Android application, other times it was during browsing in Google Chrome... I even had a freeze when only File Explorer and Image VIewer were running in foreground.
Could you help me with this problem?
Thanks,
Leonid

Try removing one of your memory sticks and run it that way. Try one at a time and in different memory slots to fully test your memory.
Run a boot time virus scan
Run a full disk check to test the hard drive.

TS1702 Just had to have my iMac reinstalled due to a fault. Now OK, but I have lost iMovie, iPhoto and pages which i had already purchased. How do I get them back ?

How do i get Imovi, Iphoto, and pages back after have to reinstall my operating system due to a fault ?

If you bought them from the Mac App Store then they should show in the Purchases tab in the Mac App Store app on your Mac. If they were pre-installed then you might be better off asking the iMac or Mavericks forums, this forum is for questions about the iTunes store.

PCMCIA Hardware Fault - Tecra 750CDT

Hi...
I have two identical Toshiba Tecra 750CDT laptops.
One machine will not recognise when PCMCIA cards are inserted, no
reaction to it whatsoever, no status lights on cards.
On the other machine cards are recognised immediately and work
perfectly.
When I swap the hard drive and WiFi card from the 'good' machine to the
'bad' machine, the bad machine boots normally with seemingly everything
working normally, except for no reaction to the WiFi card, not even a
staus light on the card.
Swap back to the good machine and all works perfectly again.
Ive taken this to mean that there is a hardware fault in the PCMCIA
circuitry of the bad machine.
Can anybody tell me whether there are any protection devices, fuses or
whatever, on laptop PCMCIA circuitry ?
Any suggestions will be gratefully received.

Hi
This unit is about 9 years old and it is not known to me but I recommend you to check all BIOS settings. Maybe you will find something there.

Am having problems upgrading RAM on the KM2m Combo-L (MS-6738)
All working perfectly with 1 x 512Mb DDR RAM in DDR Slot 1 (Bank 0 & 1) - soon as I upgrade with second 512Mb/256Mb stick in Slot 2 (Bank 2 & 3), system becomes unstable and crashes unexpectedly in WinXP. All RAM checked in other machines/Slot 1 - OK - Memtest reports no probs. All BIOS Settings normal - all 4 DDR banks are seen OK. Have 3 of these boards - all the same problem.

Freeze due to spoolsv.exe

Hi All, I am here for two reasons:
Firstly, to tell everyone that my Firefox is freezing due to some issue with spoolsv.exe and when I reset spoolsv.exe (from command prompt: "net stop spooler" - then "net start spooler") all is OK again; in the hope this will help someone else as "Freezing" appears to be an issue with a lot of people...
Secondly, does anyone know what this issue is and how to solve this?
Some months ago I loaded the wrong printer driver into my computer and spoolsv.exe became unstable. I cleared all printer drivers, replaced the spoolsc.exe file from a backup and deleted the appropriate keys in the registry. This mostly solved the issue. Every once in about a fortnight, spoolsv.exe crashes out with an error but re-starts with no issues. So I know there is something glitchy about but this doesn't cause issue with other programs.
I am running Windowes XP sp3 with the latest Firefox and updates.
Thanks.

Thank you for the reply Iamjayakumars,
Unfortunately I have tried the process suggested in the link before posting this request and went the extra step of clearing the registry keys as I described.
This issue only manifests with firefox. Is there any other information I can give to helps solve this issue?
Thank you.

New ipod touch, hardware fault(?)

So,I've bought an ipod touch 4g,8gb on last friday,and I could connect it once to my PC,it was working well.Then on the other day,the accumulator was submerged,I've tried to do something with it,but nothing happens,and it's not even possible to connect it to my pc,nothing happens when I try to do so.I've just tried it with 3 different computers,still the same.Can it be a hardware fault?If it is,is it possible to get a new one instead? :O
I have no idea what to do right now..

To get a computer to see the iPOd try:
iPhone, iPad, iPod touch: Device not recognized in iTunes for Mac OS X
and/or
iPhone, iPad, or iPod touch: Device not recognized in iTunes for Windows
Otherwise, as theother poster said, make an appointment at the Genius Bar of an Apple store or call AppleCare under the provisions of your warranty.

Bought a new 64 GB 4S version, but "About" shows only 13,6 GB. Any suggestions except for hardware fault ??

Has anybody else had problems with an iPhone 4s loosing the ability to log on to wifi. My network say is apples fault due to hardware issues in the latest release. Anyone know anymore?

Can anyone help with this issue please?

Hi Chris, the problem is after the ios7.1 update my wifi will no longer connect. I contacted my network and they said they have received an email from Apple saying its a hardware issue and nothing my network can do ( soft reset, general reset or factory reset wont work and to contact apple directly. I was told that this is most common on the iPhone 4s. Online I have seen people being offered an option to buy out of warranty phones because this issue can't be fixed? That can't be correct can it?

1Ghz TiBook - Random freezing. Logic board fault?

Hi all,
perhaps one of you might be able to help troubleshoot this, because it's seriously driving me up the wall! I bought a used 1Ghz Titanium (DVI) recently and I'm finding that it freezes randomly when in use, requiring a comand+control restart. I've almost always experienced it in Safari, but also once in Entourage, illustrator and also in MacOS 9.2.2 Finder. Essentially what happens is that the cursor freezes and the powerbook no longer responds to keystrokes or trackpad input. I've tried an external mouse but that doesn't fix things either. The display is still lit but any moving graphics/video are frozen on screen. If music is playing in iTunes it cuts out leaving the last second of sound looping. Shortly after freezing I sometimes hear the fan come on, so perhaps there is a part of the powerbook still working after the crash (?). Also, I can select/deselect the caps lock and number lock keys and the green LEDs switch on and off, so perhaps it's not completely dead? The moment of the freeze almost always coincides with a mouse/trackpad click on the scroll bar, menu, safari menu bar, dock icon, form submit button, etc. It will on occasion freeze overnight when there is no mousing at all. generally though I can leave it playing iTunes all night and when I start using it in the morning it'll freeze when I collect my email or something.
the frequency of the freezing is semi-random; I have gone for roughly 48hrs of constant use without incident and then suddenly 2-4 crashes in short succession (ie, within about 10 mins of each other). Generally it freezes about 2 or 3 times a day. They do often come regular clumps.
Initially I thought it was Safari, or the OSX 10.4.5 installation that came with the powerbook, but I removed the entire HD and replaced it with the working drive from my Pismo and had exactly the same symptoms. Realising it was hardware related I did the usual drill of swapping, re-seating and removing ram, etc - but no dice. I've run Apple Hardware Test in a couple of 18hr loops but they return a glowing report about my hardware! techtool does likewise. I took it to the new Apple Centre in London where they ran their (apparently more powerful) AHT CD for 73 loops over 3 hours. Again, no reported errors!
I've read the long 'trackpad cable thread', and opened my powerbook to see if pinching the cable is an issue, but it's clearly not. I have lots of clearance around my trackpad cable and it's not in contact with any part of the case. I've even applied pressure all around the palmrest and the outside of my powerbook case hoping to induce a freeze but that doesn't seem to do anything.
What should I do next? when the powerbook works it's fine, but I'm at a loss as to what's causing the freezing. As a performing musician playing to hundreds of people a fault like this renders my powerbook useless since it must be absolutely stable and bullet-proof on stage.
thanks for reading and I'm grateful for any advice.

hi there,
thanks for the welcome. i've been visiting here for a while and find all the posts very useful.
the trackpad issue is an odd one; my powerbook doesn't seem to show the classic symptoms of weird startup chimes or jerky cursor movement, etc in the other thread. I nonetheless opened up the powerbook praying that I'd find a pinched cable since that would have been so easy to fix. unfortunately there's nothing about it that looks problematic.
I had also suspected heat as being an issue and searched this forum a couple of times for related posts, but couldn't find anything. When I opened the powerbook i checked the fans for obstructions and blew out any dust i could see (i didn't have compressed gas). Again, they looked fairly normal to me - i didn't spot anything obvious like a trapped cable. As far as I can tell all 3 fans come on OK. First one of them and then after some time another one or two turn on after the powerbook has been running a while. (Is it actually possible to determine whether or not they're all working?)
It's difficult to say whether heat is actually related to the freezing. certainly I often notice the fans come on before a freeze, or right afterwards, but just as many times that's not the case. what is consistant however is that the freeze occurs the instance a cursor selection is clicked.
would you say this would be resolved by a logic board swap, because I know someone selling one. On the other hand, I'm a little confused by all the error-free reports I get when I run the Apple Hardware Test for extened loops.
thanks again for your help!
