Z61m Error 188 and battery

[AdrianPL]

Hey...
recently i started getting the Error 188 Checksum was wondering if there is anything i could do to fix it, for now pressing ESC works to bypass it, also my new battery worked flawlessly and this morning the laptop wont turn on, AC cord has to be attached to power on the laptop and than i can unplug it and it will run on battery any help with those two issues ? or is thinkpad the biggest garbage i bought...

I would first replace the CMOS battery (under the palmrest), and then think twice before calling your TP names...

ah i just had problems with it from the day i ordered it took 2 months to get it shipped... and always issues with something now that the extended warranty expired im sol

anyone else has any ideas cause replacing the CMOS battery did not help.... service center advised to replace the main board....

You could try updating/reflashing the BIOS.
