Question about Acer Aspire 5500 5570-2609 Laptop

2 Answers

Keyboard lag My Acer 5570 has a pronounced keyboard lag, especially when typing rapidly or using repeated keystrokes. For example, words like tomorrow and support usually end up as "tomorow" and "suport." It is very frustrating and time-consuming to have to make extensive corrections of everything I type. I also have tried adjusting all the setings for the keyboard and touchpad but those have not helped. It has a Pentium dual core T2080 with 1024MB DDR2 RAM. I purchased the laptop from Best Buy in Sep 07. Any help would be apreciated! Thanks.

    Hello Pterocarpous,

    Thanks for the quick reply.

    (05) I have Vista

    (06) I don't have any Accessibility features (e.g., Sticky keys, Hotkeys) enabled

    (07) No other issues besides the missing keystrokes.



  • Doug237 Apr 11, 2008

    Helo Pterocarpous,

    (08) I am definitely NOT a very fast typist

    (09) I should know this for sure, but I assume my laptop is under a standard 1-year manufacturer's warranty. I did not purchase any extended service plan

    (10) I did speak with Acer (emails, and phone support), and they recommended I send the laptop in for diagnostics. I would prefer to keep that as a last option, as I would probably be without the computer for close to a month (as wel as having my personal info stored on the computer potentially lost/compromised.

    (11) Yes, it's been a problem from the start, although I didn't use the computer until I had it for more than a month (not a smart move, in hindsight), and then when I did start using it I assumed the typing problems were just the results of an adjustment period on my part - not the case though!

    (12) No changes.

    I appreciate you looking into this. I am a bit concerned that Acer does not seem to be recognizing this as an issue despite the fact that numerous customers hav reported this problme to them (based on what I've read on various websites/blogs). Even customers who have sent their machines back to Acer have not had the problem fixed. Very discouraging!



  • Doug237 Apr 11, 2008

    I appreciate all the help and suggestions, but I was hoping to see if the problem could actually be corrected versus masked (e.g., with an external keyboard).

    I guess I'll have to hope that at some point Acer will own up to the problem and offer a fix somehow.

    Retailers (such as Best Buy) may also want to warn their customers, or perhaps even cease carrying the product - this more than anything might get Acer's attention!

    Thanks again.

I had the same lag problem, jumpy cursor too. On my Aspire 5520 I deleted the ALPS (third party?) driver. Upon restart windows installed it's own driver in place of the deleted one. No more problems.

    I almost forgot. For anyone about to try said solution, if you delete Synaptics or ALPS driver you'll lose the software i.e. touchpad options menu. Some people find it a bit of a pain not being able to disable tapping, but that was a trade off that I was willing to make. Hope this helps.

    My apologies, Doug237. I missed your statement that you'd already changed the keyboard properties.

    (05) What operating system is your computer running?

    (06) Are "Accessibility" features enabled for the keyboard? Make sure they're all disabled.

    Thank you, btw, for providing us w/ details on your hardware. I really don't think this is going to turn out to be a hardware or RAM (capacity and amount) issue. You have plenty there. I'm hoping it's just going to be a configuration issue.

    (07) Are you experiencing any delays or any other issues at all w/ this system (applications opening slowly, etc.) or is the problem confined to the keyboard rate.

  • B Joan Rapier
    B Joan Rapier Apr 11, 2008

    I meant to say I don't think this is going to turn out to be a CPU speed or RAM amount issue. It could be a hardware issue. We'll need to find out a bit more - try a few things to determine that.

  • B Joan Rapier
    B Joan Rapier Apr 11, 2008

    Thank you, Doug237.

    (08) This might seem like a silly question but bear w/ me; Are you a very very fast typist?

    I've had some clients who have been and they've experienced issue related to keyboard input, too. Usually, though, the issues were rectivied in the keyboard properties.

    I'll poke around some more and see what I can find.

    (09) In the interim, would your computer happen to be still under warranty? Usually they're covered for a year (laptops) unless you buy an extended warranty.

    (10) If it's still under warranty, have you spoken w/ Acer support on this issue?

    (11) Forgot to ask this initially - has this been a problem since you 1st got the computer?

    (12) If it wasn't a problem in the beginning, can you think of any events that took place in the time shortly preceeding or corresponding w/ the beginning of the problem? (OS, software or hardware installations, updates, upgrades, removal, uninstalls, crashes, etc.)

  • B Joan Rapier
    B Joan Rapier Apr 11, 2008

    Not a good sign if this is a known and, to date, no corrected issue. I suspect that until they (Acer) offer a fix for this problem, you're stuck w/ it. However, we may be able to come up w/ a work-around for you.

    (13) Have you tried connecting an external keyboard to this laptop?

    Try a USB (hardwired) keyboard rather than a wireless one for now.

    Wireless has its own set of problems. So, let's keep the variables at a minimum by testing w/ a wired keyboard.

  • B Joan Rapier
    B Joan Rapier Apr 11, 2008

    Please, in future, let us know up front - in your original post - **ALL** the information you have regarding the issue you are seeking help on. In a case like this one, where the issue is known to the manufacturer and, yet, they've refused or been unable to correct it, there's really nothing we can do short of re-engineering your laptop for you.

    While it is unfortunate you are essentially stuck w/ this problem, there is an available work around - that is using an external keyboard as I suggested.

    I'd use the warranty service, too, to address this issue. Since this is a known issue, they may attempt a repair anyway even if your warranty has expired.

    Thank you

ACER laptop keyboard skips when typing on Internet email (Hotmail or Yahoo), seems to be fine on Word?

Your browser is lagging behind. You may be low on RAM. This happens often when you have multiple tabs/windows open. Some browsers require more resources than others, I'm not sure how they compare.

It could also be low bandwidth; either you have a poor connection or are downloading a lot (via frostwire or utorrent or something) or uploading.

If you're running 768+ MB of RAM on Windows XP, you're fine. That's unlikely to be the cause.

If you're running 1.5+ GB of RAM on Windows Vista/7, you're fine.

Due to how IRQs are processed, the fact that it works fine in word but not via the internet suggests your web browser (Internet Explorer, Firefox, etc) is the problem. Try installing the latest version of whatever browser you use. If this doesn't work, try installing an older version. lol.

My letters and words will randomly go in different places

Have you checked the moue and keyboard settings see if there is something in the computer I would recommend to check the keyboard wiring but with two that would be quite a coincidence. If the mouse is chasing the cursor then its got to be a software issue..also run spyware software on both. Spyware captures keystrokes so could be affecting the keyboard pointer settings.

Keyboard - misses keystrokes with repeated letters

Good morning!
Although this does sound like a keyboard mechanical problem, I'd suggest that you contact Acer support via this link:
In the lower right hand corner of the support and service block, click on "email Support" and ask your question. I am aware of a BIOS memory flash that they came up with for one of their Travelmates, so maybe they have something similar for your model.

Since this seems to be a common problem, I'd doubt that replacing the keyboard would do much to fix the problem. Other than that, maybe you'll just have to type slower when using that keyboard? ;o(

If you need any additional information, please feel free to ask. If this information has assisted you in the resolution of you problem, please return here to give my assistance an appropriate final rating. If this information has answered your question and/or lead to a resolution, please rate it as "Fixya!".
Thank you, and have a super day!

It's like my keyboard is high.

Sounds like you use this quite a bit, don't you? I'd suggest that you may have actually worn out the keyboard. These things are built basically of plastic and heavy usage will cause wear and binding.
Hop this helps.
