(8/28/2023) Lenovo: At Lenovo, safety is our number one priority and we are concerned with any report of a potential safety issue involving our products. Lenovo’s Customer Relations team has been in direct contact with the Submitter of the Report. When asked to send the battery referenced in the report to Lenovo for analysis, the Submitter communicated that the battery had already been disposed of. Consequently, Lenovo is not able to analyze the hardware to determine a root cause of failure, if any, or to determine what, if any, corrective actions may be appropriate in the circumstances. The reported battery model is not within the scope of any current Lenovo product recall.

The company’s comments, in its own words

(1/12/2016) Lenovo: We at Lenovo are concerned about any report of a safety issue involving one of our products. Upon learning of alleged incident, Lenovo’s product safety and customer care teams reached out to the Submitter of the Report in order to (1) confirm that a Lenovo product was involved; (2) verify the facts relating to the alleged incident; and (3) obtain the hardware so that we might perform diagnostic testing in an attempt to ascertain what, if anything, occurred and if additional measures may be required.
Lenovo was able to make contact with the Submitter of the Report, and requested that the battery be sent to Lenovo at our cost for analysis. To date, the battery has not yet been received.
Since the system that is alleged to have been involved in the incident reported was not purchased directly from Lenovo or a Lenovo authorized reseller, we are unable to confirm at this time that it was, in fact, a Lenovo product or that Lenovo authorized parts were involved in any failure. From the information provided in the Report, however, it appears that the system is approaching ten (10) years old. We have no record of service based on the part number provided, can cannot confirm whether the subject battery was an original part (which , given the age of the system is unlikely) or a replacement part authorized and approved for use in the subject system by Lenovo.
Based on the information provided, it appears that neither the battery nor the system identified in the Report have been the subject of any Lenovo recall, and are unaware of any history of defect or other internal issue with systems or batteries of that vintage. Without the subject hardware we are unable to verify the facts in the Report or understand what failure, if any, or other factors may have contributed to the conditions the Submitter reported.
We will continue our attempts to obtain the subject hardware from the Submitter of the Report so that we can perform testing and any resulting analysis of the alleged incident to determine if additional measures may be required.

The company’s comments, in its own words

(6/2/2015) Lenovo: We at Lenovo are concerned with any report of a safety issue with one of our products. Upon learning of the Report, Lenovo first confirmed that the subject battery was not included within the scope of Lenovo’s current voluntary recall. Our team then contacted the company to further investigate the incident. We learned that the company’s IT department retrieved the batter from the user, confirmed that the battery was not within recall range, and provided the user with a replacement battery from the company’s existing stock. They then performed analytics on the subject battery and advised our team that it did not appear that a thermal event had occurred within the battery or any of its component cells, and that it appeared to be functioning properly.
Lenovo has requested that the company provide us with the subject battery so that we can perform our own diagnostics in order to confirm the company’s internal findings, and will evaluate any additional measures if they are warranted.
