Acer :: 5920g Died. No Sound Or Lights At All. Mainboard Failiure
Jul 23, 2009
The power light above the machine indicates that it is off, no sound etc. the ac adapter still runs on another machine. machine has 3 years static use.
is it an obvious mainboard failure?
can i safely buy a new mainboard?
Is it worth fixing seeing as the GFX is Nvidia 8600m and may fail anytime (although it never plays 3d games so surely should last 3 times longer than a heated one???).
should i sell the ram, graphics, processor, and laptop for spares and buy a different one to be cost effective?
What steps should i take to figure it out, fix it, else to find my sister an new one?

Ma lappy will be 2 years old in august, but it seems battery alredy died.
I do carry it around quite a lot, but most of the time I work on AC power.
Few weeks ago I had to work on battery and to my surprise laptop went into hibernation in less than 5 minutes after power on. Filled back to 100% and tested -- battey indicator counted percents down to 0 literally inf front of my eyes.
Is there a way to determine battery status? Might be some cells that are damaged? Any Idea what might gone wrong?
Laptop has 2 year warranty, so it's still covered for few months, but I doubt that is also true for battery only.

My Acer Aspire 5920G appears to have 'died' and I thought I'd try here before contacting Acer. Despite being under warranty, Acer have found loopholes to charge exorbitant fees every time something goes wrong.
the 2.5 year-old laptop was working perfectly last night. This morning, I opened it and:
T: Pressed power button
T+2secs: DVD drive clicks on, hard drive spins up, everything seems normal
T+5secs: NumLock light flashes, but visible POST/BIOS *does not appear*. The screen never shows anything.
T+8secs: Hard drive is still on but ceases activity. Operating system is not loaded.
(I took the timings at a subsequent attempt, but every attempt follows the same pattern)
I've tried:
- running from battery, AC and both
- reseating the memory modules
- replacing and removing the hard drive
- booting with a boot disk in the DVD drive
- booting with an external monitor attached
to no avail. From this end, I'm not sure what else I could try. Clearly there's no 'good' time for a laptop failure, but this is a pretty terrible time, so I was hoping to avoid Acer spending 6 weeks deciding how many hundreds to charge me.

Over the last few days I've read countless posts abt the same problem as I've been having with my Acer Aspire 5920G. It all started a week ago. I had shut down my laptop the night b4 and in the morning as usual I pressed the power button to start it up, it started up, completed POST and then powered on with a blank/switched off LCD screen and I could hear it going all the way up to the Vista log-on screen...... all this time with a blank screen that had no power. I kept it for a few minutes and then switched it off.
When i tried to restart,........the laptop powers on, the Bluetooth light comes on and the Hard drive led flickers a couple of times and then it'll just sit there unable to load the BIOS! Naturally I thought something was wrong with the BIOS for it to not start or complete POST. But I had absolutely no idea where the BIOS battery was located, so I couldn't do very much abt it (now I've some idea where it is, after a week of tinkering with the motherboard.)
But just to be on the safe side, over the last week I checked the RAM (which was OK), took out and reseated my GPU board (seemed OK, the GPU could have been the culprit coz of the blank screen), removed the Heat Sink (which was covering the CPU and which also acted as a Heat Sink for the GPU) and checked the CPU. The thermal paste that was covering the CPU had melted all around it, so I replaced it with new thermal paste after I cleaned it. Then I disconnected and reconnected the Heat Sink Fan and put it all back together. It didn't restart! The same symptoms as b4 appeared again. But this time after a few secs, it went into an infinite loop of powering on and restarting every 5 or so seconds.
So I thought, I'll give it one last go b4 chucking it for a new laptop! Since the first symptom of the whole problem when this all started was a LCD screen that wasn't working...... I removed all the coverings of the screen and detached and reconnected the two LCD inverter cables connected to the inverter boards thats located just below the screen and then after removing the back covering of the LCD screen, I detached and reconnected the LCD cable just behind the screen. The attachment of this cable is very fragile and flimsy. I've a feeling that this is what caused all the problems. It did seem loose!........

When at home I use my laptop (Vista Home Premium) connected to external Labtec speakers and an Acer port replicator, which in turn is connected to an LCD monitor, keyboard and mouse.
Normally all is well.
I quite often use my laptop during my travels and sometimes when I return home (and it is only sometimes) I get no sound from the speakers in the laptop or from the external speakers. The muting is right across the board, internet, music, DVDs etc.
I have checked everywhere I can think, such a laptop sound control, screen icons and Control panel, and everything seems to be set for sound.
I can get round this by re-installing the sound drivers but this is a bit of an overkill.
For a start where should I check to ensure that the sound is not muted and what is the likely cause of the muting?

I remember on vista I was playing dirt 2 for a while, and the main menu music sounded incredible. Awesome deep loud sound.
Now on win 7, It seems do dull and lifeless and low. I have the latest realtek HD drivers for the 5920g. Everything is on max. Played around with the settings.
The speakers are capable of so much more, need more power delivered to them, NOT just a higher equaliser setting. Its so annoying having the volume on 100% and not being able to hear much.
Does anyone know of a way or modified drivers that boost the sound up? Such a shame, you should be able to use the speakers to capacity. I.e the point at which they start to distort is where you stop. I need at least 200% volume to achieve this.
Also what 64 bit druvers from realtek offer the best quality sound? Has anyone exprimented with this? I id notice a difference between versions in the past on vista.

My studio 1557 recently had a motherboard failure of some type. When I would plug in the power cord, the blue light on the cord would go off. I noticed this after I was reading online and the laptop suddenly, without warning shut down and would not turn back on.
A Google search suggest that this came from a motherboard failure. I replaced the motherboard.
Now, when I plug in the power cord, the blue light stays on and it is charging the battery. The small white light above the power cord plug-in stays white while the battery is charging. But, when pressing the power button, nothing happens. The white charging indicator and the blue light on the power cord stay illuminated, but the laptop will do nothing else. No beeps, no lights, no sounds.
I assume the power button has failed. Am I assuming correctly, or is there anything else I need to check?

I just had a blue screen of death (dump screen) for the third time in 2 months and after reboot, i get this screen:
What can i do now? I would like to recover the files i have in the HDD, as i know if i send this to Acer, they'll wipe out everything or replace a new HDD. Can i open the laptop and try to plug the HDD to some enclosure to get the files out?
Will that void the warranty?
In the BIOS, i see:
HDD Model Name: None
HDD Serial Number:
ATAPI Model Name: None

I bought an Acer 5672 WLMI a little over 2 years ago. I thought the Acer offered good value for the money. The specs were Intel Core Duo processor T2300, 2GB RAm, X1400 ATI Video card, 120gb HDD, 15.4" screen, winXp Pro -cost of the system was $1800 + tax (Canadian dollars).
The 5672 always ran hot. It was almost hard to keep it on my lap it sometimes got so hot. I was not even gaming. I was just doing standard web browsing/word processing. The bottom of the latop got so hot that is basically disintegrated most of the Microsoft WinXP Certification sticker. I pulled the bottom cover off and there was nothing obstructing the CPU Fan. I also would intermittently get a green/blue? line about 3-4 inches wide down the middle of the screen. This green/blue line was intermittent. Generally, the screen problem and the heat problem became worse as the 5672 became older.
After 15 months the hard drive failed. I put in a new 160gb HDD. Acer never gave me the original winXP CD and the Win XP Certification Sticker had burned itself off. I reinstalled another copy of winXP Pro that I had. The laptop ran ok for a bit, but then the wireless starting acting up...I would get dropped wireless connections and sometimes it could not detect wireless signals that I knew were there. I stopped using the wireless completely.
After about 18 months the CPU fan started to make an intermittent noise. At approx 2 years, the CPU fan failed completely. I thought I could replace the CPU fan, but realized the CPU was an intergrated unit with cooling tubes and cooled the CPU chip in addition to some other chips on the motherboard. I checked the Acer web site and did not see this part listed (not many parts were listed). I checked on ebay saw a few posting for a new fan/cooling unit -cost was approx $170. I debated whether or not I wanted to spend $200 and time fixing a 2 year laptop...that always ran hot and had some potential screen issues.
For a few days I ran the latop with no CPU fan and used an external fan to try and keep everything cool. I had motherboard monitor and could see this was not working and temps were getting high. I was debating what to do, when the laptop just died. The screen displayed a bunch of funky colours and then it just died. I was able to power it up again, but a few minutes later it did the same thing (funky colours on the display and shutdown by itself). I tried rebooting and nothing..it was dead. I pulled the hard drive and checked that it was ok...............

Like many others who use this series, I was faced with a dead HP laptop 3 weeks ago, giving nothing but a blank screen and 3 beeps (1 long, 2 short).
It turned out that almost all models under this series had this same problem due to the NVidia graphic card that overheated the mainboard So I sent mine in for repair at the HP service center and just got it back a few days ago.
I was just wondering if there is any way at all that I can prevent the new mainboard from overheating like this again? I would like to my notebook to live as long as possible from now on.
I checked the temperature just now and it was at 75C. It said the threshold was at 105C...

I've just changed the hard drive from original to an SSD (cloned image) and changed nothing else.I've put it back together but when I press the Power button, nothing happens at all.
The battery shows fully charged, but there seems to be no power going to the system itself. When I plug in the power adapter, the light comes on for 1s then shuts off (I suspect that's just because the battery is charged) Is there a power reset somewhere if the battery has been out for a few days?

I had left the Acer plugged into the power socket in the wall. There was a power problem in our building and the electricity went and came back about 4-5 times over a span of 30 mins. This has happened before so I paid no attention to it. However, after the electricity supply stabilized, I casually looked to see that the charging lights on the Acer was not on. I unplugged the machine from the wall and tried to start it up - nothing happened. I took out the battery waited for a few minutes, put it back in and tried to start it up - again, nothing happened. I took out the battery and plugged the machine into the power socket in the wall and tried to start it up - again, nothing happened. As it stands, the Acer is dead.
The specs are T6660 (I am not quite sure about this but its something close), 2GB RAM, 250 GB HDD, Vista Home, integrated graphics (X3100).
One other point. You know the power brick from Acer has a green light on it which comes on when you have it plugged into the power socket on the wall. When I attached the power chord to the machine, the green light becomes dim and flickers. However, when I disconnect it from the machine, but keep it plugged into the power source on the wall, the light is on as it should be.

Yesterday a sony partner changed the mainboard in my z. Vista runs fine but the z didn't power off! When i shutdown the system it will reboot!
Hibernation and Standby also doesn't work - the screen went black, hdd is working and after a few seconds the desktop is back!
What can i do? I've tested some of the recovery points without success.
Same problem when starting in safe mode!
For information: when shut down in the bios everything is ok, also when booting from an ubuntu cd!
There must be a way to fix this - i hope without doing a system restore from the dvds....

I have an N7110 (2011, warranty expired) with NVidia GPU. The power jack recently broke, and when I was sent a replacement, I was sent a 5 pin one instead of the 8 pin (with one redundant pin) I required.When I connected the 5 pin to see if it would power up, the screen started what looked like a graphics diagnostic. It was flashing red, blue green if I remember correctly.
Then after a reboot, it started beeping 8 times and the screen back light doesn't work. I can just about see that there is output to the screen, but its to dark to read.I now have the proper 8 pin power jack and lead connected.
I know that 8 beeps indicates an LCD failure, but I'm not convinced that this is the case. When I connect another screen via either VGA or HDMI, I don't get any output to the screen. This makes me think that there is probably a problem with the motherboard or graphics card.I don't want to waste €100 on a new screen only to find out that the fault is on the motherboard, and if I have to replace the motherboard, I don't think its worth it since this would cost almost half the price of a replacement laptop.

Right down to the matter at hand. Yesterday I was working on my laptop, plugged in, but charging, about 40%, when all of a sudden it shuts down. I wasnt doing anything overly stressful, CPU's were each at about 50% load tops (Ubuntu 8.10, mysql, apache2, rythmbox, firefox, opera, some file browsers, pidgin).
My initial thought was that the power supply adapter had gone - thus it was draining whilst i worked and i hadnt noticed (since the connector is a little worn). I noticed that the little green light was blinking rapidly on it. However when I unplugged it from the laptop, it returned to its static green state.
I went to remove the HDD today as i had to get my work from it, so I thought I would try to start it up anyway. Nothing. Whilst removing the HDD i noticed an occasional clicking (3 little consecutive clicks to be precise, as if it were trying to start but just couldnt. This happened a few times, until I removed the battery, then it stopped. I can replicate this by turning it on and it will keep happening until I remove the battery.
Also I have gone inside, attempted to clean any dust off and cleaned the battery contacts, so it is unlikely to be anything like that.
I know its an old laptop these days and sometimes these things die, but this thing has been my baby. I learnt to code on this thing, I learnt Linux on this thing and I'm not giving it up without a fight.

This afternoon my Acer Aspire 5600's 100GB ATA/IDE drive died on me (lots of clicking/grinding sounds, nonstop disk read errors). I was looking around for a replacement but all I can find in stores are SATA drives. Can I find a reliable IDE drive somewhere for cheap? Would it be worth putting in a solid state drive (if one can be found for $100 or less)?

I bought my daughter an ACER ASPIRE E11 for Christmas. Before New Year's day I was on line with Tech Support because it was not powering up (no lights, nothing). Support had me press and hold the reset button on the bottom, and it worked. He said something about static build up , which made no sense to me. But he said it shouldn't be a problem again...but last night it did it again. I pressed the reset and that resolved it.
My questions are---"Is this going to be a continual problem? Is it something that I should send back to Acer to get fixed? Or is it something in the way we are handling it??"

I can turn off the red lights with the F9 key, but they don't stay off: the lights turn back on as I continue to work.
Is there a way to PERMANENTLY turn off the red lights? I love the laptop but HATE the red lights.

If I plug in the charger the LED light turns on with orange and if I leave it, it will eventually turn blue. Yet will still not power up. I have a new battery for it. I have tried removing battery and letting it stand then hold power button for 1 minute then plugging in but that didn't work.

when I hit the power button, the fans kick on and a couple lights turn on, but nothing happens- the screen remains blank. I don't even see the acer splash screen like usual. Also, I'm pretty sure that the hard drive isn't spinning as well.
I know the lcd isn't dead as I tried hooking it up to an external monitor, but that didn't work.

I have an Acer Aspire V3-772g, a relatively new laptop (8 months old), which randomly decided to stop booting.
Windows 8.1Core i7 2.2ghznVidia GTX 760m8gig's of ram (2x4gb)7200 RPM SATA
Was playing a game just fine. Shut down as normal, went to work, came home 8 hours later, attempted to boot - nothing.
Exact problem: Hit power button, power button comes on. Light next to the lightbulb (power light?) Comes on, stays solid. Charging stays solid orange/blue.
HDD light? Flickers. Screen flickers a dark grey color that may be the very initial part of a startup. No acer logo.The screen and HDD light flicker in synchronisation, at the same exact time. You can hear the fans fire up, and the HDD spin up. Screen just flickers about once per second (it's very faint.)
--Heres what I've tried---
-Removing power cord/battery, holding button for 60 seconds 3 times, plugging back in and powering up.
- Almost every varation of that, I have attempted.
-Inserting a new harddrive. Same result.
-Plugging in an external monitor. (Tried VGA and HDMI)
- Power does not transfer to external monitors. Screen still flickers on laptop, no change in behavior.
-Removed 1 stick of RAM - No **BUT** behavior changes slightly. Flickering of screen and HD light reduced to about once every 45 seconds rather than once every second.
-Removed both sticks of RAM - no flickering, no HDD light flickering. Pure black screen.
-Rotated the sticks of RAM - No change.
Also interestingly, with everything normal, if I hold Fn+Esc, the computer will do a new startup process (Screen still black), then after about 20 seconds goes into the normal screen flickering/HDD indicator flickering. Different behavior, slightly.

My 5920G which I got for Christmas is giving me some problems.
I have gone to power options and and changed the settings so when I close the lid, nothing must happen. But when I come back in about 20 minutes after leaving the lid closed, there is no way of me getting the LCD to start up. The only way I can get past this is by pressing the power button in for a few seconds forcing it to shut down. Obviously this is bad for my notebook. How do I get this sorted out? The same thing happens if I leave the lid open and come back in a while.
