after new battery install, boot and system freeze problems
 

I am a newbie ... but learning fairly fast (mostly on my own mistakes and the help of this community).

I bought a new battery from what I understand to be a reliable source for my dual boot (Win7 / Trusty) X60 ThinkPad; I'm finding that on battery, the machine will now not boot properly from initial GRUB screen - very slow or stops loading entirely (so I have a black screen with a cursor arrow in the middle); on some boot attempts, I am able to get to the login screen and it takes 3 minutes to load my desktop. Or ... I get no desktop and need to reboot by pushing power button. If I plug into AC, it continues to load. But ultimately, the system goes through major freezes I can't resolve without pressing the power button to reboot. The system is essentially unusable.

What is odd to me is that when I put the old battery back in - I now get the same problems. There had no problems on battery before!

I'd followed the instructions that came with the battery (turned off machine, installed and charged battery); ubuntu was the partition I booted into after doing so.

Now - I have a bunch of Thinkpads, and bought a bunch of batteries. I have this new battery in a different X60 as I type this - also dual boot. Seems to be ok, although it reported a 'system error' to report on boot - didn't catch the type of error. THIS machine does not have cpufreq installed - the first machine does ... don't know whether this could have any relevance.

Booting into Win7 partition, these problems do not occur.

Help?

Not sure what to tell you. With me. I bought brand new A/C adapters for a couple of my Netbooks and the mouse cursor freezes.
Tested in XP and Linux so it is a irq or hardware thing. Boot and running not effected and I get by with a external usb mouse while on the A/C adapter charging the netbook.

I have found batteries on laptops that kill the laptop and run OK after pulling the battery and running on adapter.
Hardware being bought can be a hit and miss kind of deal. Especially how bios sees the replacement hardware and assigns
a irq location for it. Kinda beyond my knowledge skill set also.


I used the part number on a good A/C adapter/charger to find the replacements I bought. They were the exact same but were for IBM some other brands other than my M&A Companion netbooks which are rare netbooks any ways.

Hopefully someone more hard ware proficient will chime in on this thread.
Links to laptop specs and link to battery bought specs will improve your responses also.

Very grateful for your support ... uncertainty notwithstanding! It would be great to get a helpful troubleshooter in on this ... I think this is going to mean a clean install ... again!
