Question about Acer Aspire 5742 Notebook

1 Answer

Power goes on and off continuesly

My acer aspire 5742 turns on and off continuously without boot-up, the only way to stop it is to remove the battery.. I've tried to remove the hard disk and switch it on again, yet it worked, I've gone to bios settings to configure ... but of course, i can't use it without my hard disk. I plug my laptop's hdd to my desktop pc to check for available files from it, but yet same thing happened. any of my devices as long as my laptop's hdd is in there never boot up... do you think my hard disk is now defective? how will i retrieve my file if based on that situation? thanks in advance.

Yeah, i think your HDD might be lifespan is nearing it end.
if you want to back up your data inside that HDD, assuming you gonna buy a new HDD soon, just give your current HDD to the seller and they will gladly extract whatever they can from it to your new HDD.

SOURCE: acer 7720 will not boot

Do you want to try and see if a 'Linux LiveCD' boots? This is the way I test if the computer works. You burn this CD to a disk, and then boot off of it when you're computer starts. I will not modify anything on your computer as long as you go to 'Try Ubuntu with out installing'

Don't worry, I'm not trying to get you to install anything, just see if it boots into the 'live environment' (means you are running it off of the cd) If this works, that means that it is only your windows installation is messed up, and a reinstallation of windows should work fine with a Windows install CD NOT the recovery cd.

SOURCE: Acer Aspire 3050 will not boot - LEDs flashing 8 times

My Gateway did that it was due to the power adaptor being loose on the motherboard. Push the cord in and rotate it and continuously push the power button if it starts that is your problrm. You can temporarily fix it with tape once you discover where the cord wants to be or you can use a clamp.

I don't think that you can still update the BIOS of a dead motherboard. But in your case, you can still try these steps if you haven't tried them yet, one might work for you.

- Take battery and ac adapter out then press the power button for atleast 15 seconds. Try to power on the laptop using the ac adapter.
- Reinsert the memory module/s (RAM) of the laptop. In some cases, the unit will not POST (power-on self test) if one of the memory modules installed in the unit is incompatible or defective. However, loose connection may also cause the issue. I suggest to swap memory modules on the slots (if you have 2 memory slots) or test them by turning on the unit with only one memory inserted. Using a good known memory module is also effective.
- If you have an external monitor, try to plug it to the unit and see if you can get an external display. This step will further isolate if you have a motherboard or LCD issue.
- Replace the motherboard or video card if you get nothing from the external monitor.
- Replace or check connections of the LCD cable, LCD inverter or LCD backlight if you get an external display. Note that these last 2 steps require technical expertise; however, if the laptop is still under warranty, then call your hardware manufacturer.

Hope this helps.

Aspire 5742 turns on and off contiously

After you remove the hard disk, did you try to boot the machine with a bootable flash drive or CD/DVD? Booting from a Live Linux disc you create on a different machine (free for download and use) or something like that will determine if the rest of the machine has any issues or not. If it will boot like that, then you may have a faulty hard disk, and need to replace it. I hope you have been backing up your data if this is the case.

If there is extreme heat inside the laptop, this happens. Clean the fan and put new thermal pste/thermal pad to processor and chipsets. Also check for power button problem or any stuck keys in the keypad.

Acer aspire 5742 pew71 u01 motherboard is dead what can i do

Remove the main battery and power up, no change! the power supply should be checked for correct output voltage, if okay! the DC jack in the laptop is a common source of trouble from no power to intermittent operation, at this point I would recommend having the motherboard evaluated.
