I still remembered my earlier computer, which could run everything with significantly less Mhz and only one processor core, but never mind.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_1.jpg\" alt=\"\" width=\"1096\" height=\"290\" class=\"aligncenter size-full wp-image-18684\" srcset=\"https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_1.jpg 1096w, https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_1-300x79.jpg 300w, https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_1-1024x271.jpg 1024w, https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_1-768x203.jpg 768w\" sizes=\"auto, (max-width: 1096px) 100vw, 1096px\" \/><\/p>\n<p>In the settings, everything was set to &#8220;Best performance&#8221;. Usually, this setting already causes the full performance to be available. Unfortunately, not with my HP notebook.<\/p>\n<p>Next I looked in the power plan settings, there is usually a setting like this:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_2.png\" alt=\"\" width=\"404\" height=\"442\" class=\"aligncenter size-full wp-image-18686\" srcset=\"https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_2.png 404w, https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_2-274x300.png 274w\" sizes=\"auto, (max-width: 404px) 100vw, 404px\" \/><\/p>\n<p>Here you can set the CPU to 100%, for battery mode. However, there was no such setting. Instead, I turned to IT department (greetings go out) and after some searching on the Internet, a BIOS update should remedy the situation. <\/p>\n<p>And indeed there was improvement after the BIOS update. After all, there was now 1.2 GHz. My guess is that HP set the throttling a bit lower here because no one can work with the 0.6 Ghz anymore. With 1.2 Ghz it went then at least somewhat.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_3.png\" alt=\"\" width=\"790\" height=\"280\" class=\"aligncenter size-full wp-image-18688\" srcset=\"https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_3.png 790w, https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_3-300x106.png 300w, https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_3-768x272.png 768w\" sizes=\"auto, (max-width: 790px) 100vw, 790px\" \/><\/p>\n<p>But this could not really satisfy me in the end. So I looked into the bios again. There are various energy settings, but all of them did nothing. <\/p>\n<p>However, there was still a setting, which had not hidden in the power options: &#8220;Max DC performance&#8221;.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_bios_en.jpg\" alt=\"\" width=\"800\" height=\"600\" class=\"aligncenter size-full wp-image-18701\" srcset=\"https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_bios_en.jpg 800w, https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_bios_en-300x225.jpg 300w, https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_bios_en-768x576.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/p>\n<p>Well, and lo and behold, from now on it also worked with the maximum performance in Windows.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_5.png\" alt=\"\" width=\"763\" height=\"340\" class=\"aligncenter size-full wp-image-18692\" srcset=\"https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_5.png 763w, https:\/\/ekiwi-blog.de\/wp-content\/uploads\/2022\/02\/hp_cpu_5-300x134.png 300w\" sizes=\"auto, (max-width: 763px) 100vw, 763px\" \/><\/p>\n<p>Translated with www.DeepL.com\/Translator (free version)<\/p>","protected":false},"excerpt":{"rendered":"<p>Only little performance in battery mode on the HP ProBook?<\/p>\n","protected":false},"author":1,"featured_media":18694,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1551],"tags":[1879,1880,1558],"class_list":["post-18700","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-hardware-en","tag-hp-en","tag-notebook-en","tag-windows-en"],"_links":{"self":[{"href":"https:\/\/ekiwi-blog.de\/en\/wp-json\/wp\/v2\/posts\/18700","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ekiwi-blog.de\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ekiwi-blog.de\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ekiwi-blog.de\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/ekiwi-blog.de\/en\/wp-json\/wp\/v2\/comments?post=18700"}],"version-history":[{"count":0,"href":"https:\/\/ekiwi-blog.de\/en\/wp-json\/wp\/v2\/posts\/18700\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ekiwi-blog.de\/en\/wp-json\/wp\/v2\/media\/18694"}],"wp:attachment":[{"href":"https:\/\/ekiwi-blog.de\/en\/wp-json\/wp\/v2\/media?parent=18700"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ekiwi-blog.de\/en\/wp-json\/wp\/v2\/categories?post=18700"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ekiwi-blog.de\/en\/wp-json\/wp\/v2\/tags?post=18700"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
