Acer Ferrari 4005 freezes and does not switch on again easily

Hi, i am having trouble with my Ferrari 4005. After some time (random) it just freezes and then i have to turn it off and it needs a random amount of tries to switch it on again. Each time the power LED blinks and the HDD starts spinning but the notebook still is black and nothing else happens. i already read a lot of posts referring to this problem but i did not see any useful solution. so here is my approach to provide all the information i could gather. it might also solve problems Here is what i already checked: - Running the notebook without HDD and CDROM attached brings the same problem - Memory test did not find any errors - Temperature stays below 50 degrees (also have Akasa Laptop cooler attached) - Problem appears when running with battery - Problem appears when running with power + battery - Problem appears when running with power - battery - Problem appears when throttleing CPU to 50% Does anyone have a clue what else to check? Is this a mainboard issue? Anyone found a solution to this problem yet? Is this common? Does warranty cover it? Thanks Thorsten

Mine does the same thing. I run an external keyboard and the problem disappears. I replaced the internal keyboard and the problem is still there when I use the internal keyboard. I ran a burn-in test on the hard drive. It failed. I replaced the hard drive - no change in the problem.

Re: Acer Ferrari 4005 freezes and does not switch on...

When and if it's running, run 'dxdiag' to see if windows reports any sound and video conflicts. It could be the graphic card; as i think(correct me if i'm wrong) that this model has seperate dedicated graphics, other than being on board. I'm assuming all drivers are ok and none of the vga or dvi ports give you any video either. Although the graphics are independent, it's not like a desktop pc graphics agp card, they are; as far as i know integrated in the motherboard, so the board may be the but of your problem, in which case is a replacement worth it or is it within the warranty period.

How do i power up my acer ferrari 4000

Remove main battery and try again, if nothing! check power adapter for correct voltage, If okay! sub out the ram memory one at a time and test, still no change! the DC jack is often the source of trouble and the laptop will need to be dismantled down to the motherboard level, the DC jack will probably need resoldering.

Ferrari 1000 LCD failer

Hi, Your post "Would a failed Inverter on an Acer Ferrari 1000 cause the system to not recognize the installed LCD?" No,the inverter only provides the high freq high volt for the backlight. Monitor/LCD recognition is part of your video/display controller. Pls check your video drivers (ATI Radeon Xpress 1150). Also your Default Monitor Properties. Hope this gives you some idea, Good luck and pls post again how things turn up. Kind regards.

I have an Acer Ferrari 1000 laptop and when i switched it off, it says "configuring updates", however it seems to freeze there and when I switched it off and on again, it automatically goes to "configuring...

Several questions:

When did this start?

How long have you let it sit working on this?

What was changed {software, hardware, project you were working on} shortly before this started?

With the info you have already, it sounds like the windows update, or some other update has ran & is now finalizing. Next time this happens, let the system chew on it, and wlak away for about an hour. Sometimes if an update has not been done for a while things tend to pile up like water behind a dam, and to get through it all it will take some time. Trust me, my mothers computer had not been updated for anything for over two years & it took over half a day for it to do its thing. Just be patient, hopefully this is all that is happening

Upgrading HDD in acer ferrari

5400 to 7200 RPMs? yes, but the speed change may not be that noticable.

in cloning, it is best if you use a software, if you do this often, i'de recommend the Norton Ghost, but if this is just a one time operation, just use a safe freeware to create and image of your exsisting HDD.

here's a link you may want to look at. this is page 2, you may check pag 1 about the Ghost.

Acer ferrari dead

no, Laptop Computers do not have fuses.

How are you sure the AC adapter is working? Do you have a power tester...if you don't I suggest sticking your tongue into the power tip, if it shocks you, it means it working.

Also try taking the Battery out, sometimes a bad battery will prevent it from powering on.

Lastly check to make sure you didn't break the DC jack tip (the part of the laptop you plug the adapter too) this is probably one of the most commonly broken parts on a laptop.

DVD playback is warbling

Have you tried viewing in a different software, as i found that acer use a form of Power DVD as their standard movie player which comes installed with the system. Try viewing in media player for example.
