Acer Aspire 7750g Owner's Thread

[popeye1128]

Hi! I'm not sure if I'm posting this in the right place, but here goes:

I've been using the 7750g since January-ish with absolutely no problems, or none that I've noticed. I'm not that great with computers, so I haven't tried any sort of hardware modification. I've only updated drivers and BIOS as necessary.

However, as of a few days ago, I've run into an issue: If I run a program that uses up a lot of memory or CPU (Diablo III and Crusader Kings II, both of which ran just fine before), my power cord stops working. First, the cord will disconnect for a brief moment, then come back, then shortly after it'll stop working entirely and the LED light beneath the computer's power button will blink until I unplug the cord. After I close the program and/or plug the cord back in, it'll possibly happen again, but sometimes it doesn't.

I have no idea whether there's a problem with the power cord and AC adapter or with the computer itself, and I have no idea how to figure it out short of ordering a new power cord and testing that one out. Acer support wants me to use their pay-per-problem service, but I'm not exactly keen on dishing out money for that.

Has anyone else run into this problem, or know how to fix it? Thanks in advance.

Well, one of those nasty to determine problems. Could be 3-4 things.

1. Overheating, monitor your temps with something like Speccy or another program.

2. Power Brick, the blocky looking power supply, not the cord.

3. The onboard power circuit, very bad.

4. The jack where the brick plugs into the laptop, again very bad.

Do you blow out the vents on your computer regularly with a can of compressed air?
Power bricks are fairly cheap. Is it very warm (hot) to the touch when this happens?
Slightly wiggle, not hard, the connection where the power brick plugs into laptop.

Post results if you don't figure it out. Good luck!

I do clean out my vents, yeah, but I've never actually opened the laptop to clean it from inside. Should I?

The computer never gets too hot. According to Speed Fan, the CPU never gets over 40 degrees Celsius and the GPU never really gets over ~65ish. The power brick, though, has gotten really hot to the touch, though it's not always that hot when it stops working.

Thanks for the help!

The back cover that allows second HDD is here: 60.RB002.007 - Acer Laptop Miscellaneous Parts

And most folks put the SSD in the 2nd slot and leave the HDD where it is because of the cooling setup. You can make the 2nd slot the boot drive in BIOS.

I haven't actually done it myself but I think the only other part may be a mounting bracket to hold it in place but I would think Velcro would work well also.

I contacted that company and they are no longer able to get the Hard Drive Cover that allows a 2nd hard drive. Does anyone else know of a place that has them in stock and available?

Thanks!

Here's another place: Acer 60.RB002.007 Acer Hdd Door W/2nd Hdd Refurbished

Just do a search for 60.RB002.007 door panel

Add failing motherboard capacitor to that list and I'd say the the majority of sources for the problem.

I tried them and they said they don't have them and none of their vendors have access to them anymore. This is pretty much the same story I have found with every place I have found online so far.

After sitting on hold for over 30 minutes and then getting transfered to Level 2 support with Acer I was finally given a phone number at Acer to call and get the parts. That phone number was 800-910-2237.

I called that phone number and they said they don't stock those parts anymore. I was told by the people at Acer to call Capital Data at 800-999-4409. I called and left a message because they were closed for the day. Hopefully they will be able to get the parts.

In the mean time if anyone else knows of somewhere I can go to order the parts I would appreciate it.

After searching Google every place I could find either didn't have access to the parts or the page was in German or some other foreign language.

Not good. Maybe time for Dremel tool if you're that serious about doing it.

[FMruss]

Yep, just use a dremel-

Before 1 month i got the plastic cover with 2 brackets for second drive.
Working good, but second drive working with higher temps than main slot.
( +5°c).
Waiting nearly 1 month for packet from Germany. If you want, i can ask contact for you.

Specification says : AMD Radeon HD6650M s 1 GB , no Intel HD.
With Msi afterburner i set up the clocks for idle status 300/300. Fan turning off frequently then before with 600/800.

I think that sounds like you're looking a two different sensors. The sensor for the Intel HD graphics chip is clocked by default near 300/100 and the radeon by default is clocked around 600/900.

I could be misunderstanding what you are stating, so I apologize in advance.
