It never failed, so I didn't need tot reflow anything. Luckily this one had no overheating issues, luckily because this model also has the overheating/reflowing video chip issue. The only issues were:<br /><br />1) 1 bent pin from HDMI connector, I bought it so, try to bend it back, but it broke. So I had to take a piece of the metal housing apart in order to reach the core of the connector, I glued a new pin in place from an UTP female connector and soldered it at the bottom of the connector. Works since then without issues.<br />2) 1 broken plastic core of an USB connector. Got another one and glued it in to the place. Works since then without issues.<br />3) flat band cables from touch multimedia section and power button needed replacement, got them online from dissasembly of another device.<br />4) 1 of the speakers failed, so I got another speakers section from disassembly of another device.<br />5) A fixing part of the speakers cover was broken, so I had to glue another piece of plastic to hold it in place.<br />6) The CMOS battery holder was broken, so I had to glue another piece of plastic to hold the battery in place. It gave better results than using adhesive tape to hold the battery in place.<br />7) Keyboard was originally in French. I first managed to fit my dv9000 English keyboard in it by bending the flat band cable (the same layout) to fit the connector and stuck it in place using double adhesive tape. But after a while it failed as some of the keys didn't work anymore, so I found an new original dv8 English keyboard which wroks since without issues.<br />8) I opened the laptop directly after buying it to deep clean it and apply thermal paste on all heatsinks. Never needed a deep cleanup since then.<br /><br />It is not my main laptop, but I use it when I need to do for example sorting tasks at which the big screen and the extremely comfortable keyboard and touchpad use make things faster to complete. The main laptop is an Acer Spin 5 15,4" touchscreen device with i7 8th gen and dedicated video, but although it was an expensive device it doesn't give that feeling of premium that the dv9000/dv8 still does. The complicated but succesful process of having Windows 7 on this device is worth in another post mentioning. The main idea is that the device is UEFI Class 3, so no CSM, therefore you need to use some emulator (vgashim) to get standard vga running to boot it or by slipstreaming the intergrated video driver, which you need to sign it using a custom certificate (and also slipstream the certificate using remote registry editor), because there is no official driver for integrated intel video cards starting from 8th gen, therefore you need to modify a 7th gen driver, which removes the officialy signed flag. But it's simply worth it, because Win10/11 is simplu trash.Andrewnoreply@blogger.comtag:blogger.com,1999:blog-3889671357708757904.post-84524625429110592602023-11-02T08:17:32.448-07:002023-11-02T08:17:32.448-07:00Joseph S, Thank you for posting the Equus.exe file...Joseph S, Thank you for posting the Equus.exe file. <br />I have confirmed that the Equus.exe file is the same copy as mine and matches the SHA2256 hash.<br />I'm surprised anyone is still running an HP dv9000 laptop. <br />bjohnsonhttps://www.blogger.com/profile/12732076798193822967noreply@blogger.comtag:blogger.com,1999:blog-3889671357708757904.post-53746338130854380132019-08-14T09:53:15.761-07:002019-08-14T09:53:15.761-07:00Hello, can you share equus.exe ?

I couldnt find a rrplacement board so it will go to the cemetery. I am moving to a dv8 which i found at about $250,I just can't quit these gorgeous pavilions. The owner said it had no issues or repairs and this model didn't have nvidia issues. Even if it's an old config, it will suit me fine, the i7 it has isn't very bad and the gt230m video card is pretty ok. Upgrading from dv9000 to this is like heaven for me.

In my opinion, the design of the fan didn't perform well to provide adequate airflow, even with the ACPI DSDT patch to increase the fan speed.

I'm still not giving it up, even if it's pretty damn old. I recently upgraded my primary HDD with a 64GB SSD ($25) and there is pretty much speed improvement. I might also get an ExpressCard USB 3.0 adapter for my 2TB External HDD now I have on USB 2.0, but I don't know what speeds would I get.<br /><br />Also, I forgot to say that I've changed my Intel 3945ABG Wireless card with an Intel 4965AGN ($2.5), in order to use 5GHz with my Dual-Band Router to achieve 100Mbps real speed over wireless (my ISP delivers real 100Mbps). My computer got locked because the BIOS whitelist didn't contain this card, so I needed to flash the unlocked BIOS (which also had SLIC 2.1 so I could easily activate Windows with any activator).<br /><br />All the best from Romania!Andrewnoreply@blogger.comtag:blogger.com,1999:blog-3889671357708757904.post-34640242538046014732015-12-30T09:09:22.423-08:002015-12-30T09:09:22.423-08:00Andrew,

I gave up having Windows 8.1/10 on this laptop, not because of incompatibilities, just because of poor font rendering in Windows 8.1/10, same with Office 2013 (caused by grayscale antialiasing instead of subpixel method used in Windows 7/Office 2010). Laptop is alive and kicking since I used you patch 4 years ago. The video chip gets broken once in a while (1-2 years) so it needs a reflow. As I couldn't find a pen torch where I live and I'm sick of paying $20 for each reflow at the laptop service. Yesterday, my screen went black and didn't get back again, so I knew I had to repair it again. I was so angry that I've risked my board and "cooked" it in the kitchen oven. I preheated the oven at 200C for 5-10 minutes, I wrapped the mainboard in aluminium foil leaving a gap only where the GPU is. Then I seated the board with the GPU chip upward on 2-3 platforms made of aluminium foil in the oven's tray, closed the door and turned off the gas/fire. I let the board there for 5-10 minutes, then got it out and let to cooldown for another 5-10 minutes. Then mounted back in and... IT WORKED. Now I know how to save my ass all by myself until I will have enough money to buy a new laptop, as this is ANCIENT... The only remaining problem is I have to buy a new power flexband cable, as the sound in the speakers is not working everytime I listen to music and power LED blinks from time to time. There are some newer white flexband cables which are far better than black stock ones and I'm getting one for $2 here in my country from a laptop service and store. I already changed the media buttons cable with one of these 4 years ago and it doesn't have a problem at all after messing up with it during the many repairs. Hope my old grandfather dv9000 will still last...

I have tried removing it, until I found the right way to do it using an application. Here it is: My WCP Watermark Editor - http://download1us.softpedia.com/dl/cc5152d95eb9c8e600e52655b0491bf1/530b91b6/100210191/software/tweak/My_WCP_Watermark_Editor.exe . Just hit remove watermark information and reboot.<br /><br />Also, I'm having some issues with dv9000 drivers for Windows 8.1. laptopvideo2go.com didn't release a modified inf for the latest Windows 8.1 drivers, so I have installed my older Windows 7 driver for the Go 7600. Newer Intel drivers for Rapid Storage SATA, WLAN and LAN do not contain the drivers for older discontinued products such as the Intel ICH7M SATA Controller, Intel PRO/1000 PL Ethernet and Intel Pro/Wireless 3945ABG. And again, I had to install my older Windows 7 drivers. The same is for Conexant HD Audio. Bluetooth drivers from HP for Windows Vista/7 do not work under Windows 8.1. But the integrated drivers from Windows 8.1 seems to be enough for Mobile Phone to PC file transfer. I highly recommend to install the latest Synaptics Touchpad drivers from their website, as I've encountered scroll issues with older drivers. I am still testing the Windows 8.1 workaround with dv9000, as it seems that older Windows 7 drivers are not the best option, but hopefully in the future there will be better drivers. I guess some of the issues are related to the fact that Fast Shutdown is not truly supported with older Windows 7 drivers.<br /><br />Another thing, bjohnshon, is that I remembered my GPU failed recently when I switched to the 26C patch version from the 32C one. My GPU temps were about the same, but CPU usage is not as high as under Windows 7 and this way the Temp1 stays cooler than under Windows 7. Therefore, very often the cooler stays very slow (as slow as with no patch applied) in IDLE and GPU is more likely to overheat. Now, I don't know if this was a pure coincidence, but I'm afraid to go back to the 26C version of the patch. Sometimes the cooler spins fast even if there is barely any CPU usage or it continues to spin fast for a while after a high CPU usage period ends. This is kind of weird. I will make more testing.Andrewnoreply@blogger.comtag:blogger.com,1999:blog-3889671357708757904.post-25530685269661497682014-02-10T16:35:14.772-08:002014-02-10T16:35:14.772-08:00Andrew,

But, this issue started in the last 5 days, because I got random lines and artefacts on the screen at random moments. So, my GPU's BGA broke again, but there was no overheating at all, as I was running patch. I guess reflowing works for an undetermined period of time. This can be days, weeks, month or years. Today, I got it reflowed again at a local shop for $10, but not using heat gun or pen torch. They used a professional temperature monitored oven and I think this is way better than home-made methods. I hope it won't break again... As I'm really sick of disassembly as I've done this way too many times because several components got damaged. I've replaced my power jack because it got loose, I've got my two flexband cables replaced, oiled the cooler twice, cleaned the dust 3-4 times, reflowed 3-4 times, modifying according to your blog and extending cooling sensor cables, left hinge cracked, LCD cover broke 2 times (last time I've strengthen the screw mounts with melted plastic and poxiline), replaced palmrest twice because of paint erasing (now I've got it foiled up with transparent autoadhesive foil). Even most of the screws got damaged because of many times of disassembly-reassembly procedures. This laptop gave me pretty much headaches since 2008, but I really don't want to buy another laptop too soon...<br /><br />I've tested the 2009 or 2012 string, but to no extend. Only the testsigning on works. This also brings a "Test mode" watermark on the low-right corner, but I can live with it. Now I'm testing Windows 8.1 Luxury by khatmau_sr. It's very good looking, fast, light and very well optimized for older machines. There are Norton Ghost backup files of it uploaded. You simply need the bootcd of Norton Ghost 2003 and restore the preinstalled backup to your C: drive. And when you reboot, you've got yourself preinstalled Windows with additional preinstalled software. You don't have to do much after this. I also loved khatmau_sr's Windows 7 Luxury, but I wanted a lite version of Windows 8.1.Andrewnoreply@blogger.comtag:blogger.com,1999:blog-3889671357708757904.post-90465828276880530942014-02-07T17:10:35.896-08:002014-02-07T17:10:35.896-08:00Andrew,

There is a section of code that identifies the Windows version and saves it. Check out section "3.4.2.3 DSDT Patch" that talks about searching for the Device(PCI0) section and add both Windows 7 and Windows 8 support. You could try the following for Windows 8 support but I don't know for sure if this is correct, so experiment.<br /><br />If(\_OSI("Windows 2012"))<br />{<br /> Store(0x7DC, OSYS)<br />}<br />I will add a section to this blog that outlines your finding and points them to your comments. Let me know about any followup you do.<br />Thanks again Andrew for sharing.bjohnsonhttps://www.blogger.com/profile/12732076798193822967noreply@blogger.comtag:blogger.com,1999:blog-3889671357708757904.post-78117579378506925342014-02-07T08:27:26.648-08:002014-02-07T08:27:26.648-08:00So I guess the problem was not the DSDT code chang...So I guess the problem was not the DSDT code changes (they don't exist), but the fact that Windows 8 & Windows 8.1 doesn't allow overriding DSDT from the start. You must change this behaviour using the command I provided. But this is not possible due to me, credits go to the user who wrote the last post in this topic: http://social.msdn.microsoft.com/Forums/ro-RO/d2663c42-70ec-4caf-a26c-441c2088578d/windows-8-dsdt-overriding?forum=wdkAndrewnoreply@blogger.comtag:blogger.com,1999:blog-3889671357708757904.post-52120131537136851752014-02-07T08:22:56.479-08:002014-02-07T08:22:56.479-08:00As I promised, I've installed a fresh copy of ...As I promised, I've installed a fresh copy of Windows 8.1 32-bit (never getting back to 64-bit because too much HDD space and RAM used for nothing I really need). I've tried extracting the original ACPI from Windows 8.1, I decompiled it and I compared it with the Windows 7 one. It's the same! No modifications at all!<br /><br />So now I tried once again to load the modified dsdt.aml I previously and successfully used in Windows 7 32 and 64-bit. Response: Table overloading succeeded. Rebooted but no luck, Temp1 still under 30C. Then, I opened Command Prompt (ELEVATED - AS ADMINISTRATOR!!!). But the command from that topic I linked in my previous post didn't work either.<br /><br />So, I removed the key written within {} and just typed: "bcdedit /set testsigning on", hit ENTER and it successfully worked. Then typed "bcdedit", hit ENTER to check if really "testsigning" was "on"... And IT WAS!<br /><br />Now, I ran the "asl /loadtable dsdt.aml" with the patched dsdt.aml and "Table overloading succeeded" appeared in cmd. Then rebooted and... voila: Temp1 = 48C in IDLE. I must say that I tested all these with sensor wire disconnected and fan at full speed. But when I saw the Temp1 = 48C after reboot, I simply connected the wire back and the cooler was running smooth at an IDLE low speed as it was back in WIndows 7 and as it should be.<br /><br />So, in order to override DSDT, you need to enable testsignin by entering "bcdedit /set testsigning on" in a Command Prompt (CMD). Don't forget to open CMD with RUN AS ADMINISTRATOR! Then, normally apply the patch with the original method you provided!<br /><br />I also tried to set "testsigning" back to "off". But after reboot, DSDT will revert back to original settings, therefore you MUST keep testsigning on.<br /><br />Regarding to Windows 8.1, I hate the Metro UI, but I will use Stardock Start8 fot the original Start Menu and avoiding that tablet-friendly (BUT NOT PC FRIENDLY) UI. Now I'm testing this LITE version to see if it fits my needs and get accomodated to Windows 8.1. If I really don't like it, I will restore my Windows 7 backup...<br /><br />Cheers!Andrewnoreply@blogger.com
