And You can quickly fix the freezing by using buttons ClickPad Enable/Disable (tab TouchPad Settings, Synaptics).
This also indicates that it is some software/driver malfunction.

Yes I have a dm1 in the UK and it has the same problem too! Seems to occur most often if I have a USB to RS232 cable plugged in. But strangely the mouse and keyboard appear to be PS2 devices!
Let me know if you find a solution and I will do likewise.

Hope this can help for the bluetooth problem in dm1-4003au..

Also having the same problems during months. Still haven't found any solutions. Just going to try give everything I've figured out.
Problem : Keyboard and touchpad is freezing at some point. (not the whole system, just the keyboard and the touchpad).
- Can get them back after have put the system on sleep and let it 'cool down'(?).
-Happen on both Windows 7 and Linux (Tried Fedora and Ubuntu). But it's better on Windows 7 (Tried Windows 8, it's worse).
- Energy Settings plays. It is better to be on "energy saving", and it's better to be on battery.
- Heat don't seem to be the trigger, but seem to be a factor. Because when the freezes appear, it is needed to let the system cooldown (or is it a capacitor which is discharging?!). Also think that it was worse during the summer so...
- Happen when transfering data trough usb.
- Tried to remove both Keyboard and touchpad (with the connector), didn't help, don't seem to be an issue with keyboard/touchpad hardware. I would more say it's on the processor.
- Better without Wireless connexion. Mostly the Bluetooth. (Tried without the wireless chip, still the issue)
- Tried to let the fan running at full speed. The issue still occurs, maybe it's the heatsink. Also tried thermal paste, seem to help a little, again, I'm not sure (like I said, the heat seem to be only a factor and not the cause).
I think it's definitely the processor, or the graphic part. Or at least, defintely something that we can't remove from the mother board. It's defintely a hardware issue, but since it works better on Windows than Linux, it looks like that the software can be/is also involve.
By the way, I have an HP DM1-4131EF
Hope it helps anybody and will help to find/resolve this issue...
PS: Don't have english as main language, sorry if there is any mistake.
Edit : From what I've read on other posts, it seems that the issue only occurs with hp pc with the AMD E-450, so I think my guess was right, and the issue is most probably on the processor. Now, is it a heat sensor, the processor, or the motherboard, that's the question... and if it's possible to resolve it into the sofware...

I take back what I said earlier,
I'm quite sure to have localized the problem. It's the chipset FCH (Fusion controller hubs), I think its reference is "AMD A50m". And I think it's a heat problem issue (bad airflow or manufacturing defect?), found by trying to cool down that chipset with an ice... x). Haven't had any mouse/keyboard freeze for 5mins in a usb transfert (could just be a coincidence, but I don't think so). And it looks coherent since this chipset is what control usb (and mouse/keyboard too I suppose), so I think we're in the right thing.
Anyone know how we can play with his heat? Is it the "AMD Sata" Driver in Windows? Is it possible to downclock it or something?
Hope it will help someone to find how to resolve this issue...

Have you tried updating your BIOS?
Have you tried cleaning the cooling vents on the notebook as per this document?
I'll await your reply.
Please click the white star under my name to give me Kudos as a way to say "Thanks!"
Click the "Accept as Solution" button if I resolve your issue.
I work for HP.

could you tell me, whether it's normal, that laptop is going hot (55-60 C) on idle (the temperature of both CPU and HDD)? When making video calls, CPU achieves 70 C. Also, it can work on battery only 1h 20 m ( from the beginning it was 1h40m).
My laptop is CQ61-222SL (with internal Intel video), bought in October 2009 in Italy.
I'have cleaned fan, heatsink, changed thermal paste and got only 3-5 degrees profit.
Is there any way to decrease idle temperature? Could it be cause of inproper drivers (yet I've used latest versions)?
