May 15, 2018 - Explains how to update Lenovo BIOS from Linux using a USB flash. F12 key and select USB mass storage device as boot source; The BIOS. Re: Bios serial number change ‎ 01:45 AM if Lenovo service provider did not change the motherboard then your warranty is voided in the first instance in which you changed the motherboard.

Not exactly true. Lenovo System Update also verifies your system with that serial number and if it is not changed you cannot use system update. I have another question. Bosch ebike diagnostic software download. My thinkpad t61 has still warranty and was sent in because the main board crashed December 2009. I got it back everything fine so far, but the repair service did not update the bios, so I cannot use the system update anymore. Lenovos support hotline tells me that I have to send it in again to fix the issue.

I think it is not fair, that I have to pay (lost time because of sending it in for about 2 weeks), for obviously their mistake. Anybody an idea what I can do? Regards Stephan Nielsen. I called (again) and talked to two different persons for about an hour (actually 3, but one hang up after 10 seconds or lost connection, whatever). They tell me it cannot be escalated because it is not possible.

They reject my customer satisfaction request. The problem seems to be that the thinkpad was sent in to the norwegian repair center because i was living for 5 month in norway.

I realized the problem when i was back in germany, so i am trying to fix the issue with the german support hotline. But it seems the global company lenovo or ibm (who i think is still responsible for the support?) is not so global at all. The first guy told me that i should call the norwegian support hotline and complain about the repair center there.

The only option the german support center has to offer is that i can send it in again because the mistake is not caused by the german repair center. That is also why they cannot except the customer satisfaction escalation he told me. The second guy told me that it is not possible to escalate the case because there is no reason for it.

I have no right to complain because i do not want to accept the warranty service they are offering me (sending it in). The only option he offered me is that they would come and fetch the laptop for the repair which might be a little bit faster than sending it. Although i told him that i will use the warranty service but only want to complain how the service was handled it was still not possible to record the complain. He told me that i would get a questionnaire after the repair is handled (sth i did not get the last 2 times the laptop was in for repair). Now i know, why lenovo has such a high customer satisfaction rate. They just do not record complaints. (i know that's not true all the time but it fits my case.) well, after this i do not know if i should consider lenovo for my next laptop, although i am very satisfied with my thinkpad except all the repairs (harddrive, cooler, battery, mainboard, cooler again) i had in three years but i still hope that my one is just a real lemon.

But thanks for the advice although it was not successfull.

I just joined, this is my first post, although I've been lurking here for some time. I'm a long time lover of Thinkpads, still using a refurb T61 (holding up but with some dings and scuffs), and my first was and old R series. I recently purchased a refurb T420, for which I've noticed something peculiar: The model # on the bottom of the machine (4177-RVU) does not match the model number given either by System Information, or when I boot to bios. The model number given their is 2912-BR4--a T410! All other features seem to confirm this is a T420, (and yes, it does say 'T420' on the indicator strip). From what I can tell, all the other specs are as described by the reseller.

Did someone flash the wrong bios in this thing or something? Or could something else more nefarious be going on? Gene_s wrote: CPU Type: Intel (R) Core (TM) i5-2450M CPU CPU Speed: 2.50 GHz OK so you definitely have a T420 board in there, since the T410 doesn't support that CPU. My best guess?
