How to reset Lenovo Thinkpad to factory settings (lost password)

227

If you are talking about the BIOS password right after you boot the Laptop you have four ways.

  1. remember the password
  2. send your laptop to lenovo and prove that you are the owner
  3. replace the motherboard
  4. change BIOS by soldering another one in place

It is a special security feature of Thinkpads that you cannot simply short a jumper and reset the BIOS by doing so. Source: ThinkPad on German Wikipedia.

    I have a process that takes a very large amount of memory, it involves manipulating large images. The process is called via get request route, and I currently have a lock on the image creation method. Without the lock, if I send more than 10+ requests at once, the application memory immediately spikes and throws an exception.

    [HttpGet]
    [Route("example")]
    public HttpResponseMessage GetImage([FromUri]ImageParams imageParams){
    
       lock (myLock){
       return CreateImage(imageParams);
       }
    
    }
    

    Someone mentioned increasing the applicationPool in another question, but I can't figure out how to do it. I think this would be a better alternative to locking, because I could still use a couple of threads to create images, but could limit this so I don't run out of memory. I am under the impression that .NET is using an integrated thread pooling system for each GET request. I am sure from testing that these requests are somehow run in parallel, and it would be helpful to decrease the potential number of threads rather than locking it to one.

    Looking at this resource, https://msdn.microsoft.com/en-us/library/dd560842(v=vs.110).aspx

    I've tried adding this element to the System.Web section but it says it is not a valid child element (even though I am running IIS version 10)

    I was able to change the aspnet.config file to change the applicationPool number from 0 (default, no limit) to 1 and 3 but this did not yield any different results at all.

    Any input would be appreciated, thanks for reading

    Edit:

    This is a followup from my question at this link, which shows the code where these errors are pointing me and some efforts to analyze..
