Text delayed when typing...?

Hi I've got a new (refurbished) MBP with snow leopard. I'm finding that the screen is really behind when I'm typing....even now as I type this I've had to wait a couple times for my text to show up several words late. ...if that makes sense. It's a bit annoying. Does anyone have any ideas about this. ...maybe it's why it was sent back?? I've only had the machine for about 3 weeks.

Sounds to me like something is taking up your CPU cycles.. and causing a lag in processing power. Try checking Activity Monitor (Applications/Utilities) and seeing if anything looks out of sorts.

How much RAM is in your machine and do you have the latest updates?

Lots of space left on your boot drive?

Does it happen in every application, or just one?

Have you tried a different user account to see if it's the same for all users on the machine?

First thing I would do is restart. If that makes no difference, repair permissions Applications>Utilities>Disk Utility>Repair Permissions. Good luck.

I don't suppose you recently cleared cache on your computer? I find that every time I use Cocktail or MacPilot to clear the cache on my iMac, the typing lag is pretty nasty for a few hours and then starts to pick up to normal again.

I tried repairing permissions and that took a few minutes so I guess there was stuff to fix. Typing seemed a bit better but then this morning I had a couple of moments of it lagging behind. Presently it is working fine.

I haven't cleared the cache on my computer...err, I don't think...I haven't used Cocktail or MacPilot but I have cleared things like my chat in Skype for example. Would that do anything?

Vexel suggested checking my Activity Monitor...I'm not sure I'd know what was out of sorts with it...but I'll take a look.

okay, looked at the activity monitor and nothing is using tons of % of cpu usage. I've got 4 Gig ram and lots of space on the boot drive (only drive). It was happening in Word and my Yahoo mail when composing text. I'm the only user. I'll see how the day goes for text writing and update if it happens again now that I've done the repair permissions.

thanks for your assistance

It may be worth a try if you're still having issues to make a new "Test" user.. and see what happens there. There might be a conflict of some sort with the software installed on your user only. Maybe a plugin, or something causing the anomaly.

I've had my text lag once in a blue moon and it was almost always because there was Flash on the website, or something similar. Tho.. it is usually limited to the application I'm using at the time.. which 9 times out of 10 is Safari.

You won't see anything unless you're actually experiencing the problem; the reporting is in real time. Leave Activity Monitor running so that you can quickly switch to its window when/if something bad happens. I find this happens sometimes with browsers - too many windows open, memory leakage (which all the major browsers are guilty of) etc. Generally a shut down of the browser helps, and failing that, restart the Mac and 99% of the time the problem goes away.

If the typing is still lagging and delayed, try shutting down the Mac and boot up into Safe Boot mode (hold down the shift key at the startup sound) and see if there's any difference when logged in.

If there's an immediate speed increase it could be due to some non-Apple extension or software.
Safe Boot bypasses and prevents any non-Apple stuff from loading.

Then just reboot again to get back to your normal boot setup.
