So this laptop was given to me a few years ago as broken but all it needed was working RAM and I had that laying around. It hadn’t been used for the past 5 months when I pulled it out to upgrade the firmware on my router. It boot up, fully loaded and then I opened a web page. The whole thing freezes but doesn’t shut off so I hold the power button to power it down.<\/p>\n
Now, when you push the power button; there is light on the power button, The fan spins up, the HDD spins up and then quickly there is a click and everything stops. After that, the WiFi Light is on, The battery light is on and the HDD light is blinking. During all of this, nothing is on the screen at all. No beeping either.<\/p>\n
What I have tried:
\nRemoving battery
\nOnly using power adapter without battery
\nHolding power button for 1min with adapter and battery removed
\nRemoving RAM one at a time
\nReseating RAM
\nRemoving HDD
\nMaking sure only the essentials are attached when booting<\/p>\n
The last two things I can think of is, the MoBo or the CPU. I can’t test the CPU because I don’t have another laptop to put it in. I haven’t pulled the MoBo out completely but so far I don’t see any damage. Is there anything else to try that I missed?<\/p>\n
My other questions; Should I fully pull the MoBo and inspect with a fine tooth comb or does this resemble a definite CPU failure? If the CPU went out, should I suspect something is up with the MoBo also and not chance putting a new CPU in here? The CPU itself runs new @$140 and used @$60. Should I put $140 into this or go used since this Laptop is older?<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"inline_featured_image":false,"iawp_total_views":7},"question-category":[47],"question_tags":[],"class_list":["post-9083","question","type-question","status-publish","hentry","question-category-hardware"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/question\/9083","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/question"}],"about":[{"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/types\/question"}],"author":[{"embeddable":true,"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/comments?post=9083"}],"wp:attachment":[{"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/media?parent=9083"}],"wp:term":[{"taxonomy":"question-category","embeddable":true,"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/question-category?post=9083"},{"taxonomy":"question_tags","embeddable":true,"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/question_tags?post=9083"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
