This is really a note to myself on how to do an emergency power reset. This is a desperation troubleshooting step if you find that the laptop won’t charge. One of my colleagues ran into this problem, and some Web searching suggested that there was a BIOS update for it, but unfortunately, the BIOS updater refuses to run unless the machine is on AC power, so they found themselves in a Catch-22.<\/p>\n
For Lenovo laptops, look on the bottom for a small pinhole near the power connector. This is the power supply reset button. Unplug the laptop from all power sources, then insert a paper clip (or similar tool) into the hole and press the recessed button for 15 seconds<\/a>.<\/p>\n For HP laptops<\/a> and Dell laptops<\/a>, there is a similar emergency reset procedure: With the laptop disconnected from all power sources, press and hold the power button for 15 to 20 seconds.<\/p>\n Acer<\/a> figured, “\u00bfPor qu\u00e9 no los dos<\/a>?” They have both an emergency reset pinhole and<\/i> a power button 15-second reset.<\/p>\n","protected":false},"excerpt":{"rendered":" Looking for the magic button.<\/p>\n","protected":false},"author":1069,"featured_media":111744,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[104],"class_list":["post-110719","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-oldnewthing","tag-tipssupport"],"acf":[],"blog_post_summary":" Looking for the magic button.<\/p>\n","_links":{"self":[{"href":"https:\/\/devblogs.microsoft.com\/oldnewthing\/wp-json\/wp\/v2\/posts\/110719","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/devblogs.microsoft.com\/oldnewthing\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/devblogs.microsoft.com\/oldnewthing\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/devblogs.microsoft.com\/oldnewthing\/wp-json\/wp\/v2\/users\/1069"}],"replies":[{"embeddable":true,"href":"https:\/\/devblogs.microsoft.com\/oldnewthing\/wp-json\/wp\/v2\/comments?post=110719"}],"version-history":[{"count":0,"href":"https:\/\/devblogs.microsoft.com\/oldnewthing\/wp-json\/wp\/v2\/posts\/110719\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/devblogs.microsoft.com\/oldnewthing\/wp-json\/wp\/v2\/media\/111744"}],"wp:attachment":[{"href":"https:\/\/devblogs.microsoft.com\/oldnewthing\/wp-json\/wp\/v2\/media?parent=110719"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/devblogs.microsoft.com\/oldnewthing\/wp-json\/wp\/v2\/categories?post=110719"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/devblogs.microsoft.com\/oldnewthing\/wp-json\/wp\/v2\/tags?post=110719"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
