Touch pad and keyboard freeze after startup

I've been having this problem myself. The thing is, whenever I disconnect the battery, everything decides to work fine. When I put it back in, everything turns into crap again. Try plugging your laptop in, but turning it on without the battery attached.

Well this might not solve your problem but it may help others. I thought I was having the wierdies! on my new Acer Aspire 5315 after happily installing Suse 11.0 and getting all but wireless to work. Yes even Crystal Eye was identified and Skype picks it up and give me a great pic.
Suddenly this morning for no apparent reason I could no longer use the touchpad only the mouse 'logitech' worked. Checked everything and then did a search using ixquick.com and got here. Tried all the suggestions including taking the battery out but nothing. Sat and pondered and then looking at the keyboard noticed that F7 had a little hand and finger pointing to a square icon just below and to the right of the F7. Umm! let see whar happens when I use the Fn and the f7 keys. BINGO!!!! Touchpad loves my fingers again.

Might help if anyone else has similar Aspires or laptops with lockout like this.

Aight here we go.

Problem:
The mousepad & keyboard is not responding after startup, and the problem is allways where you least expect it... the battery, BUT! its not that the battery isnt workin correct, its the two pads where the battery and the computer is attached.

Fix it:
Im not quite sure what the tool is called on english, but its some sorta "Glass fiber Brush"
It looks like a small pen and when you turn the buttom, some "glass fiber hair" pops up. Anyway thats what ya need, dont know if there is somthing simular to it, but il leave that to you guys. Anyway, pop out your battery, take your battery and use the "brush" on the socket where the battery meats the "docking station" on the computer itself, just rob it around abit. The problem is thats its actually "rusty" its not completely rust its the small stage before rust or whatever its called (It turns the metal light orangeish) thats blocking the way, so your screen, usb mouses, usb keyboards might work, but the keyboard & touchpad itself is not getting any power from the battery because of the blockage. Dont forget to do it on the computer socket aswell. Once i had an acer aspire 3500 that was completly blacked out, it couldn start or anything, i used the same procedurer (Cleaned the two pads) and ding! it worked perfectly. Any qutsions? Email me :)

Good luck

Uncheck the box under the driver config that says allow windows to disable this device to conserve power. Hmmm.... It works when I remove the battery, I wonder what it could be? And removing the battery does not "fix" the problem it forces the laptop to run on full power not battery power. This is a common problem with laptops. Check the NIC driver especially the wireless.
Hack

I am having this problem. I disabled 'Microsoft ACPI-Compliant Control Method battery' it worked fine. I then started the laptop with the AC power in, charging the battery from about an hour, removed the AC supply and the laptop died after 2-3mins of use, meaning the battery isn't holding charge. I have a replacement battery on order and will up date when i receive it

If you disable 'Microsoft ACPI-Compliant Control Method battery' in Device Manager, then no need to remove the battery every time. The only downfall, is you cant see how much battery life you have left.

I am having the same problem and removing the battery works. the only problem with that is that i need to use the computer on battery power some of the time. does anyone know if replacing the battery works, or another way to remedy the root of the problem?

Rakeshwar123,

Try booting in safe mode; this will just load the basic Windows services and drivers. If the problem goes away I would suspect a problem driver or perhaps even program. I once had a sound card messed up by installing a database program.

If you?ve installed a driver for the touchpad try removing that first. They cause me lots of trouble on Dell laptops.

Let us know if you have any other questions and please don?t forget to rate this posting.

I have an ACER Travelmate 4070 with similar problems....

This is quite funny but frustrating...

Yes, Once the battery is removed this problem is solved.

I doubt there is a problem with the battery, as I really got frustrated with my lap-top and dismantled the whole unit... Checked all connectors, etc... but noticed that when the Optical Drive (Combo in my case) is not connected, the laptop works well (even with the battery connected - meaning both the keyboard and touchpad work).

I reconnected the Combo drive and checked again (same problem - touchpad and keypad stopped working with battery also connected)

I then rebooted the machine in Safe mode - everything is fine (even with the battery and combo unit connected)

I restored my laptop to original factory settings (System Restore - Windoes XP, SP2) - but the problem persisted (touchpad and keypad did not function when battery connected)

I then reformatted the whole unit using a different Windows XP CD (SP2) - same problem (nothing else was installed and neither any additional drivers - just the windows default)

Anyone has a solution to this problem?

Thanks.

My touchpad and keyboard stoped responding in normals windows mode but did work in safe mode. When I looked into this problem- and after much time and effort- I found that the problem was that the battery was fucked. Buy a new battery. lithium ion batteries will wear out with time and use and the aspire 3000 is not a new computer. Batteries are cheap on amazon.

Removing the battery fixed the same issue for me as well.

well.... i read all the notes here.....the solutions here are very acurate.......it is the battery not holding charge......also if you have a charger thats not the original i suggest you throw it away.....the problem is caused beacuse of low voltages across the mother board....also if you notice the computer video chip gets super hot.
what i did:
update the bios
disable the windows acpi from device manager.
order a new battery.

any questions please call me 718 781 7825 im jose located in NY

Thank you so much guys for your help and advice. I have been looking for such a Perfect thread a week ago! ..

The post says:
Touch pad and keyboard freeze after startup! = Yout Battery is Fucked up and Expired!

Thanks for the great Post again ..

Cheers

New battery time definately

I hav a acer 5100 i reloaded windows and it stopped working

throw the laptop in the bin lol

Removing the battery also worked. I don't understand what the battery has to do with the mousepad not working. can someone fill me in as to why this is?

I will be ordering a battery soon for mine to see if that fixes the problem. My battery wont stay charged, so solution 3 makes a lot of sence to me. I will update when i get mine, b/c i know how frusterating this problem is, and to not have a solution.
