In other words, in a single "step", it goes from bright enough to a point where you can barely see the screen (and the left of the screen is darker than the right).

Ideas/suggestions ?? I know they grabbed the LCD from a similar HP laptop (but not necessarily a 2510p).

Try disabling the LED ambient light sensor in the bios and try again. Otherwise could be is a unique circumstance introduced by the third-party LCD panel as my stock supplied HP panel does an incremental decrease in brightness when pressing Fn-F9.

Seems like the SSD has indeed broken

Maybe I'll buy a new laptop

Appears the SSD is faulty -> consider RMAing it and/or waiting for a Runcore ProIV Redux SSD to be released.

i-core based 2540P, Lenovo x201, Toshiba R700/705 or Acer 1830T all worthy system upgrades to a 2510P.

I changed my os from Windows to Ubuntu 10.04 and have the first big problem...

in 10.04 you can't load dsdt tables anymore, for using custom dsdt you have to recompile your kernel and do this at every new kernel.

This is no good solution at all ...and it is annoying of course.

Can we maybe just patch the dsdt in a bios file and flash a patched dsdt directly into bios?

or do you think of any other solutions? fan is annoying loud without custom dsdt table

thx, best regards

This 2510P bios is compressed and checksum protected, so binary changes to it are not so easy. semi could help if that was required. A kernel recompile would be easiest to add the DSDT override capability.

[Evilandi666]

Thx for your help. Will try this - even if it is annoying...

I signed up to thank Nando4 for the "INFO: Almost silent fan using a custom ACPI dsdt table" mod. My 2510p has had the noisy fan problem since I got it (refurbished) from HP. I will be taking the bar exam later this month, and needed to solve this frustrating problem before I go and sit in a room with hundreds of people who would be very annoyed by it (first of all, me). I loaded the fix yesterday, and my laptop has been blissfully quiet since then.

I bought a external USB enclosure for 14$, but not like http://forum.notebookreview.com/hp-c...ml#post5622281 without bezel, I bought one with a bezel. If someone is interested in picures/howto/test ... pls say it.

Also you can put me in your list in the first post, i've got the ebay ide caddy working with a WD Scorpio Blue 250GB Pata (WD2500BEVE).
Edit: I have nothing in my 1,8" Bay, so you can but "none" instead of "???" there
Edit2: And i have a custom dsdt table (but with -for me- better values than you put in. My fan doesn't go from 30% -> 70% because 70% is very loud (and sometimes i reached the 70% for a short time). I did a slower step like 30% -> 50%. This is better for me.)

But one thing is not good, there is this little latch between the caddy and the HP ... did someone ever try to replace the caddys faceplate with the one from the Multiburner?

[Evilandi666]

My Enclosure came today!

To say this one first: It fits nearly perfect and the quality is very good.

Here is the album..

Next step is to put the old faceplate on the harddrivebay adapter to close the latch.

HP BIOS F.0E bug? 2 healthy batteries stopped charging, orange LED continuously on.

Hello 2510p lounge,

The problem started 10 days ago: nearly 3 years old 6-cell battery would not recharge beyond 31% although a few days earlier it was fine with over 5 hours available. Orange "charging" LED remained on. Status (in Vista and Ubuntu) indicated it's charging. But the battery's charge never went up. I tried draining it completely until the laptop shutdown. Here I was with a 0% battery that would not charge itself. As dead.

I then bought a brand new (pricey) 6-cell battery. Plugged it in: 37% charge, supposedly charging. Next morning: still 37%!
My BIOS was F.04. I noticed a BIOS upgrade on HP's support site:
HP Compaq 2510p Notebook PC- Download drivers and software - HP Business Support Center

Si I upgraded BIOS to HPQFlash F.0E. ...and Hurrah! Both batteries then loaded to 100%. 5.5 hours of usage available again with my 3 yrs old battery.
Did the HP battery check software test: both batteries healthy.
But it was only a short hurrah

I then discharged the battery to 35%. Plugged the charger back in. Same problem as before: no real charging (Vista & Ubuntu), just the usual lie. I tried with the newer battery too: discharged to 93%, plugged charger: orange LED on, "battery charging", but in fact the battery is not charging at all.

I also tried the sequence: turn off, unplug. remove batt, plug in, boot, shutdown, unplug, insert batt, plug in, boot.
No success.

I reflashed the BIOS again with F.0E. No effect this time. No success.
Did the HP battery check software test: both batteries failed the test. I checked contacts with voltmeter. Voltages look good both at battery and laptop connectors.
I see other people with other HP laptops have been experiencing similar problems:
http://forum.notebookreview.com/hp-c...battery-2.html

Does anyone have an idea what's going on? How can I get my 2 healthy batteries to charge again nicely like they did the night before, less than 24 hours ago?
I like the wifi's blue LED... does my laptop need Viagra?

You probably just need to reset the battery's internal calibration. Easiest way to do that is uncheck the "Critical battery alarm" in Power Options then run your system on battery till the battery is completely flat and powers off. Then proceed to charge it which will now accurately know it's "full charge" which is likely a lot less than it was indicating previously.

If upgrading batteries to a 9-cell suggest check if the 2540P can be retrofitted. Visual inspection from youtube/web pics indicates it might be. It's a higher 93Whr spec as opposed to the 83Whr spec of the 2510P/2530P 9-cell.

Thanks Nando4 but I've tried your suggestion before and stayed with a flat battery (the older one) at 0%. Also, the new battery is stuck at 93% and there's no reason why this one would need to be calibrated.

Thanks again for your attempt to help.
