HP/Compaq :: Dv6500t BIOS Recovery
Aug 14, 2009
I've been following the thread below, but so far have not found the key to recovering from a failed BIOS update on my dv6500t laptop:
CQ45- Insyde BIOS RECOVERY using a USB THUMBDRIVE
I can press Windows-B upon bootup and I hear a single beep followed by the USB floppy spinning up briefly. Note that if I turn on the computer without pressing those keys there is no activity or sound, so I think I'm on the right path towards a BIOS recovery.
The problem is (I believe), I don't know what filename the recovery process is looking for.
I've tried: BIOS.BIN, BIOS.ROM, BIOS.WPF
Also: 30CC.WPH, 30CC.BIN, 30CC.ROM, as well as 30CCF58.WPH.
I've tried this process with a USB flash drive and an SD card, but only the USB floppy drive gives me the feedback that file activity is actually happening (this means that I don't have enough disk space to try 50 copies of the same file with different name combinations).

Several weeks ago I replaced the power socket on my dv6500t because I had to pull the power cord in a certain directions. (see the thread here: dv6500 Power problem) For a few days it seemed to help although I moving the laptop in a few directions still cased the AC power to cut out.
Now after a bunch of weeks, it's back to where it was before. i.e. I have to pull the cord in basically one of two directions to get AC power. I'm assuming with these symptoms either the power socket on my laptop is screwed up again or there is something wrong with my power cord. Could it be anything else?
At this point, I feel like it's probably the power cord, but I don't want to pony up 150$ only to find out I'm wrong. I could send it into HP for them to fix it. It's a nice machine (core2 2.4ghz, 4 gb ram, etc)

Realizing that my computer is now a little over 2.5 years old, I had a little time to think about whether I should even think about going over to a brand new notebook. Given the specs of new notebooks these days (and a lot of people know here that I spend quite a bit of time at the HP website/FTP), I was wondering what everyone here thinks about me going for a Quad Edition notebook.
In case you're wondering, I use my dv6500t notebook extensively mainly because I am a UCSD Computer Science/Engineering student who does a lot of activities on the computer both casually and for work, for a good portion of the day, everyday. If I get a new notebook, I plan on using it extensively as well.
The specifications for the dv6500t that I currently use is listed in my sig. It additionally has a 12-cell battery which at this moment can only charge up to 58%, and a rather broken left TouchPad button. Warranty is pretty shot at this point, since I had the 1-year standard (which I have no regrets with).
Now, the Quad Edition notebook that I was specifically looking at was the pre-customized HP Pavilion dv6-2190us notebook:...........

My HP dv6500t doesn't return from standby and/or randomly crashes when I have my 2x2GB 800MHz OCZ RAM installed. I'm not sure if it's the size (4GB) or speed (800MHz) that is the issue, but it's something, so I need to make a change.
Which of the following RAM configurations would be better/faster? I don't get errors configured with them.
1x2GB 800MHz (single channel)
2x1GB 667Mhz (dual channel)

I got my dv6500t with an 8400GS card to output to my 1080p HDTV but the problem is that the image that displays on the TV is only 90% of the full image as shown on my laptop.
This is via HDMI.
I'd like the images on both laptop and HDTV to match perfectly and I've tried every combination of resolution between the TV and the laptop yet I always get the same result: a fully displayed desktop on my laptop and a cropped desktop on my HDTV.

I'm getting a strange problem on my dv6500t with my dual booted Windows 7 RC install (same issue with the Beta). My searches have been inconclusive.
Using W7 as one user is fine, but if I leave one user logged in and switch user accounts, things start acting wierd...Anti-virus fails to start (I've uninstalled AV and the rest still occur)Can't use the IE button on the task barIE doesn't log in to some websites (e.g. AOL mail)slowness Lots of permanent window and menu artifact ghosting that only clears after logging out This only happens when 2 users are logged in at one time... one user works just dandy.
I'm just suspicious of my HP... the friggen thing crashes on me enough or doesn't resume from hibernate/sleep so I'm not confident in the crap.

Today i upgraded my dv6500t again. This time i put in an OEM t8300. After putting it in the bios reads it and it runs fine ( Im on it right now ). Anyways i will be using it and it idle's nicely at 40*C to 50*C but randomly it will jump to 83*C for core 1 and 97*C for core 2 the fans will spin full speed then it will drop down right back to normal. Anyone have any idea i am running the most up to date bios F.59.

I had to upgrade my BIOS to the latest one but I found out that I was viewing a different model. Now when I bootup my laptop, all I see is a black screen with a flashing white line.
How can I recover from this error? I've been trying out several "Crisis Recovery Methods" but they don't work. I've used all key combos for boot-block but only Winkey+B makes three beeps. Maybe I'm doing something wrong? I put the right BIOS.wph in there too. I also did a CMOS reset and nothing happened. I bought a $41.99 external usb floppy drive because of this!

I changed my HP to boot with legacy CSM, but I couldn't boot from the Windows 7 boot disc. The laptop was shipped with Windows 8 configured for UEFI boot before my change.  The screen after boot is blank and now I can't even get to the bios menu.Â
Â
I have tried a Windows 8 USB recovery drive, but the computer doesn't seem to try to boot from flash, even with the hard drive disconnected and the CD tray open.Â
Â
I watched a video of a man disassembling an HP Pavilion completely down to the base plate, but I did not see a back-up or RTC battery anywhere in the computer. If I could find the bios back-up battery for removal or reset the bios somehow with the hardware, i would do that. I waited for 4 hours without the main battery attached without any change. At this point I don't know if this model Pavilion even has backup battery. How to reset the bios to default UEFI setting without a bios menu? Note that pushing F2/F8/F9/F10/F11 and a whole bunch of other keys does not bring up the bios menu at boot time (like it did when it was in UEFI mode).
Â
My next steps are to use the HP Recovery Media application on a 2nd computer to create 6 Window 8 DVDs and see if these will boot from the CD. If that doesn't work, I'll contact HP support and see if they can send me a custom recovery disc.Â
Â
It seems strange to me that I can't even get to a bios menu in legacy mode. Is this normal? I suspect that my configuration change corrupted something and no booting will work any more. If booting from disc doesn't work, I think I'm stuck with trying to drain whatever back-up power source keeps the bios in-state, however long that is.

I’ve just done a clean install of my Dell Vostro -- reinstalling vista and removing the recovery partition in the process. Outcome = a ‘cleaner’ machine with none of the preinstalled bloatware/c**p from Dell. (first time I’ve done anything like this, but followed a brill guide in the Dell section of this forum ).
I’m about to tackle my Mums Compaq Presario C310EA. The aim is to remove all the rubbish she has accumulated over the years, incl any spyware/ adware she may have, and generally have a bit of a clean sweep…. hopefully resulting in a faster laptop. I’m backing up her data, and moving some of my Dad’s stuff somewhere else.
Basically I want to clean up as much as poss, but unfortunately she has no xp disk, just the recovery disks (cds) she burned when she first got the laptop.
As she has no xp disk I guess the best I can hope for is to reset the laptop to the factory settings (?) .. not ideal, but I don’t think the (factory set) bloatware is too much of an issue for her – she’s not a heavy user.
Should I use the recovery partition for this, or do I need to use the cds she burned? .
I’d like to know the best approach – and can’t seem to find a set of instructions to follow.

Acer 9300
I was trying to play a video and the computer froze. I waited several minutes and nothing responded. I finally had to hold the power button to shut it down. Now it will not go to the bios screen and the screen shows a bit of brightening but does not go anywhere.
I've googled for a solution and there are several pieces of possible solutions I have found but as is too often the case, there were no follow up answers to make the posts helpful or, the answers came tantalizingly close like the following for a similar problem with an acer aspire 5315:
"1. first download the attached zip file and unzip it.
2. burn the extracted disc image to disc using nero.
3. place the newly burned cd into your laptop cd drive tray
4. remove the battery and power cord.
5. press and hold FN and ESC keep pressed and insert power cord and then press the power on button
6. your notebook should power up but without any display.
7. you should see the cd/dvd drive activity light blinking as it reads from the recovery disc.
8. if all is well your laptop should power itself down after about 2 minutes
9. once it has powered down remove the power cord and wait about five minutes.
10. finally insert your battery and power cord and power up your laptop in the normal way............
