Hello Everyone,
I have a HP Elitebook W8560W with Win7 Pro x64 which is my work laptop. It was not given to me as new and it looked a bit beaten up. But it was working, really hot but working. So a few months back I disassembled and changed the thermal paste, cleaned and saw that there was a resistor that one of the welding points on the graphics card was looking burnt. But everything was still working fine.
System specs:
I7 2670Q 16GB DDR3 1600MHz Nvidia Quadro 2000m Samsung 850 PRO 256GB (this is the new one) HP Dockstation Win7 PRO x64 with server based user (when I need, I can use the desktop workstation in the office with all my "User" files already synced)
The situation now is, my work laptop on a cold boot, shows the Bios screen and the initial Win7 screen loading up. Once I am supposed to see the credentials to unlock, I hear the Win7 opening sound, but I get no image on the laptop screen.
Now 2 things can happen.
1 - CONNECTED ON DOCKSTATION (or with the power chord) If I am connected on the dockstation, The external screen shows the credentials screen and I can login and everything shows up except for: - Laptop keyboard does not work; - Laptop screen is not available; - Laptop touch pad also does not work.
2 - ON BATTERY If I'm only on the battery power, I can press the power button once for the laptop to sleep, and again to wake-up, and now I have the backlight up on a black screen. If I keep trying sleep/wake-up, I can get it to actually show the login screen and go into windows on the laptop screen. and now everything works. - Laptop screen works; - Keyboard/touchpad on the laptop works; - If I connect again to the docking station, I get external monitor on top of the laptop monitor and external mouse; - Basically everything works as normal.
So, as some extra info. As the cold boot is happening, everything works because I can get into Bios and do everything (with touchpad/laptop keyboard/external mouse/external keyboard).
Also, If I go to Win boot options with F8, and I pick any of the Safe Modes. The Laptop boots Safe Modes just fine on battery, OR If I'm in the dockstation, everything on the external interfaces.
In a short summary: - If using docstation/power chord -> everything works externally - If on battery -> after some sleep/wake-up cycles Everything works internally and externally, and even connecting again to dockstation/power chord.
I tried to understand the issue, but I can't fully relate the issues. If I boot from a Windows CD on the dockstation, I also get the image/input only on the external monitor/external peripherals. Also if the boot drive is Linux based. I do the same on battery, I get the image on the laptops screen and I can use onboard keyboard and touchpad (which by the way, does not happen with external booting source on the dockstation).
In a side note, this has been happening for a few months but I only needed to do office work, but now I have a little of free time so I'm trying to fix this. And if I have to go on the field, this is going to be a disaster. Just to add up, the ssd gave the chkdsk error 766f6c756d652e63 3f1. I managed to fix it with a new ssd. I created an image of the previous ssd with Yumi/Acronis, loaded the image in the new ssd with the same Yumi/Acronis. Then booted up, still had the chkdsk error, booted from Win7 CD, made a repair, and now it is back on where it was before.
What I tried so far:
1-Fresh drivers installation (original driver release for the laptop and most recent nvidia drivers);
2-Deactivating unnecessary services from starting and apps (VPN, G-DATA, dropbox and even some windows services) once these failed to give any result, I activated them again and the issue remained;
3- System restore, but as the hard drive was always full with server backups and working projects (running simulations uses a lot of disk space) the option was not activated and I had no restore points;
4-Windows startup repair, no option from the F8->Startup repair option gave any changes.
The only reason why I didn't try to do a fresh install so far, is because I have lots of software on this, and with server managed licenses and it would be an absolute pain to install everything again. Probably would take a few days to get it back on working condition again. I already have the backups, just in preparation for the worst case scenario.
So, any ideas? I'm sorry it this was too long, but I wanted to leave (what I think) is as much relevant information as possible.
Cheers.
