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
I have same problem, when it was new, sent back came back worked for one year then out of warranty and same thing freeze up. Have sent back to acer and paid for so called repairs 4 times with no luck. I get it back and within 15 minutes does the same thing exactly. Obviosly they have no one at their acer repair centre that understands how they work inside?I have same problem, when it was new, sent back came back worked for one year then out of warranty and same thing freeze up.

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:
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.

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.
i'll try make it simple..disconnect all input mains power
sources.."just remove or pick open the cmos battery (+3v) from the
main/mother board and resit/fit it again carefully".. configure bios again..save n exit n restart..hope it'll work.. always better to hv professional supervision, contact ur system admin/vendor....
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
reseat the memory of your computer. basically, it will require you to open the computer and reseat the memory modules. then, start reinstalling XP again.
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.
how unsurprising..you will find the elevating it from being flush on the desk will go a long way to helping with the heating effect..too long that way, and bye bye to the uProcessor.
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.
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.
