Acer :: Aspire 5755-6647 / USB 3.0 Drive Connecting At USB 2.0 Speed?
Jan 27, 2014
I have a Western Digital 1TB USB 3.0 external drive. I am connecting it to the correct (blue) USB 3.0 port on my Acer Aspire 5755-6647 laptop which runs Windows 7 x64.
Upon connection, I get the "This device can perform faster: This USB Mass Storage Device can transfer information faster if you connect it to a Super-Speed USB 3.0 port" message. When copying files off the drive, I get about 32 MB/s, which corresponds to USB 2.0 speeds.
I have tried disabling USB power management in the USB 3.0 Host Controller Utility. I have tried uninstalling the device and reinstalling it. The cable I am using came with the drive and is a USB 3.0 cable. I have the newest Renesas USB 3.0 driver installed (2.0.34.0). I have also tried using an older Renesas driver. My BIOS is up to date (P5WE0121).
The first time I connected this drive to my laptop, it was on a USB 2.0 port (I had for some reason misremembered which side of the laptop had the 3.0 port and didn't check for blue). As I said, though, I've uninstalled the device completely. I suspect that Windows may be "remembering" the device and installing it with the 2.0 driver.

I have an ACER ASPIRE 5755 laptop with 4GB RAM and 500 GB Disk. Now the issue I am facing is, it doesn't boot up. It just sits at a screen for sometime and then even if we reboot it goes to the same screen which is much prior to loading Windows and I believe just after the POST. I checked in the BIOS that hard-drive was not getting detected. I unplugged replugged ..took it out, put it back in but nothing worked. Than I removed that hard-drive and replaced it with a working hard-drive of my fren's & eventually it booted up fine. Hence this isolates to be an issue with the hard drive. Now my question is that, "is there any upper limit on the size of the hard-drive (as the inboxed one was 500GB)". I am planning to take 1TB hard drive. So will that work In addition to this, is there any link provided by Acer which I can browse and check what all Hard-drives are supported / compatible / recommended by Acer. I have been a big fan of Acer Laptops from a long time and would not want to buy a new laptop just because of this simple hard drive issue.

I have an aspire 5755-6699 that has been giving me problems. It keeps freezing up and going into windows recovery at startup. Windows recovery stopped at checking and fixing disc errors. So I bought a new hard drive and put it in and tried to restore it with the recovery disks. Everything went fine until the very end with the language disc. The top bar went to 100% complete and the bottom bar stopped at 99% and just stayed there. I tried to restart the computer but it says there is no valid disk drive. Tried running e recovery again and the same thing happened. What should I do?

I'm having probs connecting wireless my Acer Aspire 8730. I had this issue 5 days into buying this laptop. It seems to be an intermittant problem as sometimes it connects fine but other times it doesn't. Sometimes it finds other available networks but not my router. Comet sent the laptop back to Acer who insist there's not a problem with the network card. I did find a setting on my router for extended range that we have checked but the problem still persists. If I connect via the ethernet cable then no problems but if I sit the laptop next to the router it still doesn't connect wireless. It seems to have completely lost the plot over Christmas and can now find absolutely nothing wirelessly. I could try changing the router but I'm a bit loathed to do this as we have aother laptop that runs fine via my router. I'm not sure where to go from here as I know both Comet and Acer will deny there's a problem.

my wireless cut out this afternoon having worked since i bought this laptop a year ago.
i've tried the 'repair' route. i've looked at the device manager and it is supposedly working, but i've had to plug into the wireless router with a physical wire to get connected to the internet. the message i am getting is that windows cannot connect to my preferred network (the one i've been using for a year).

I bought a new ext. harddrive (Verbatim 3.5" 1TB QUAD INTERFACE) in order to connect it to my laptop (Acer Aspire 5930, Win Vista, SP1) via eSATA port. However this does not work at all. The computer simply does not detect the hard drive. The same trouble appeared when i tried to connect the drive to another machine, so it is possible its simply broken down. But the USB connection works pretty well.

I have a problem with my Acer Aspire 5520M ... I it getting very very hot, about 90-91 degrees when I use it, then the fans turns on and it get's colder. It does this A LOT, and when I game i shifts between laggin and running fine. It is very very annoying, and I have NO idea what is wrong.. I even have problems running warcraft 3 in 800x600x16, which I think should be running fine all the time.
Have any of you had the same problem or have any ideas how to fix this? Should I send it to repair?
Another question, is it possible to make the CPU run max speed all the time? It is not possible to change this in the BIOS and don't know how to change it, it seems to go down to 800mzh all the time even when power is needed.

is there any way to control the fan speed of this lap top?
I have tried speedfan, rivatuner, even tried the undervolting option with RMClock (no success - the CPU was running at the lowest voltage already).
One option did present some signs of activity - Acer Asprie One (!) Fan Control utility. However, it only switched off the fan completely. Besides that, it was quite unstable and sometimes forgot to turn the fan back on after the threshold of temperature was crossed again.
By the way: computer doesn't get hot at all. The feel is quite cool, as Speedfan utility indicates these temperatures:
GPU: 41C
HD0: 36C
Temp1: 54C
Core0: 30C
Core1: 27C
It appears that I love this lap top almost for everything, except its loud operating sound.
I am running at:
ACER 5739G
Vista 32 bit,
Chipset: Intel PM45
Processor: Intel Core 2 Duo T6600
GPU: GeForce GT 130M

My laptop is an Acer Aspire 6935G with Intel C2D P8400 2.26GHz (1066MHz FSB) and 4GB DDR3 RAM. OS is Vista Home Premium 32-bit.
Under the memory tab in CPU-Z, the DRAM Frequency shows as 399MHz. However, the maximum bandwith for the memory under the SPD tab shows as 533MHz. If I'm correct this means my RAM is running at 800MHz instead of 1066MHz.
I've read other threads mentioning this problem and a solution was a BIOS update to v1.10. My current BIOS is v1.05, which has been on my laptop since new.
I've never updated a BIOS before and therefore reluctant in case anything goes wrong. The laptop is running fine with Vista.

Intel i5-2450M @2.50 GHz (Turbo to 3.1)
8GB RAM
Nvidia GEFORCE GT 630M - 1GB
Windows 7 Home Premium
I have had this laptop for about a year now and ever since I bought it it has had major throttling issues while gaming. I have tried many ways to make it run cooler with no such luck (It runs at about 95*C when playing most games) . The fan never runs at 100%, only aboout 70% (from what I can hear) so I was wondering if their was a way I could control the fan in order to run it at 100%.

I originally purchased my E1705 with a 60GB 7200RPM drive. I believe at the time it was mainly to save a few bucks and that the largest 7200RPM available may have been around 120GB and added $200 to the price of the machine.
I am constantly finding myself uninstalling applications and looking for things to delete to save space on this tiny little drive, it has gotten to the point that it is a hassle. I recently moved my music library to an external USB drive to free up about 20GB only to fill it again right away by installing Visual Studio 2008 and the MSDN Library.
I need more drive space!
I know there are a ton of options out there for drives which I can easily swap right into this machine but I am having a tough time trying to decide if I am willing to sacrifice the added speed of a 7200RPM drive for the additional space offered by the largest of the 2.5" drives.
I use this machine for everything, it is my primary computer so having the fastest available options is desirable. I frequently render digital video for the creation of DVDs and believe it or not I perform this function currently on external USB drives because of the space issues. Having th space to move this to the primary drive with the full speed interface will be a big plus.

I have a brand new Ideapad G710 with 1TB Serial ATA 2, 5400rpm with advertised speed of 3 Gb/s (= 384MB/s). I am running Windows 7 ultimate x64 with SP1.
When I test hard drive read/write speed (I used CrystalDiskMark) I get results of about 100MB/s, which is 3-4 times slower than it should be. I am not running any resource heavy applications (Resource monitor reports Disk I/O to be 0 most of the time in idle state). I have 3 partitions, each with 16-32GB paging file size and all are >90% empty. All partitions have been defragmented before testing.
Is this normal? Are there any lenovo drivers or utilities than I might be missing or that can slow/speed this?

The SSD drive would be big enough for my needs but I'm hearing they are real slow. My experience with other SS storage devices would seem to confirm this. Any experience out there with speed issues on these solid state hard drives?

I have a problem with my laptop, is an acer aspire 5672wmli, the model with 1gb of ram.
The drive is a Matsushita UJ-845-S, when it was new it had a firmware version 1.00 and they gave me some incompatible problems with some media, so i decided to flash with a newer version, 1.02 and after that the drive work well but I was unable to did the boot from cd.
The firmware page is this:

The firmware 1.02 is for toshiba OEM and this is why it give me this problem.

In the specs listed on the website, and on the sticker on the laptop itself:
320 GB Dual HDD
(160 GBx2)
I am going insane, on the device manager it says I have two HDs, but I think one of them has been partitioned, the one with the windows data on (C drive) the HDs in my computer are displayed as this:
I've been told of a program call 'Raid' or something, but I'm really not sure what it actually does.
I just want to know if the two smaller HDs are partitioned and if possible, how to join them up again,

I have purchased a DVD Writer to replace the DVD-ROM the laptop came with. With some of my old laptops, these drives were held by one screw or a spring loaded lock, but this does not seem to be the case with the Acer.
which screws in which order need to be taken out to replace the drive?

I picked up a 4730Z last week, and it has a 120GB HDD in it. I need a little more room, and am looking to add the full 4GB's of ram.
My question is which hard drive to get for this model. I'm not sure if I can use a 3.0 GB/s SATA or not or if I should get a 1.5 GB/s. I want at least a 320GB drive, but can't find any that specifically say there's a jumper option for 3.0/1.5. Search function yielded me no results either for the 4730Z specs.
