Press the power button once to wake up the computer. if still doesnt work then you need to do cold restart by pressing the power button for about 5-10 secs to restart

Win XP instaling problem on Hp probook 6550b

Hope you are using a fresh windows XP install of the entire system.
HP drivers will need to be obtained and installed before running. The error on the screen usually is a driver error and not a XP issue.

Guys, As usual this HP laptop so called business edition is turning out to be a junk box for me. Latest problem is if I am working for hours together on the laptop nothing happens, if I leave the...

ProBook 6550b (NO OS stated, is it WIN7 or Citrix?)
or XP, VISTA? (this PC has 4 choice new) fact.
we are USA so not much data here on INDIA PC's
Consider some facts:
learn that all PCs are junk boxes.!! that is right,(for 99% of world)
by bad design. (MS,etc)
all can get infected at the drop of a hat! (virus or malware or both)
all can,(unless run as a virtual machine or as ROM ONLY)
windows as you know it is a sponge, that attracts bad things.
all do. (linux not so)
can talk all day on that, subject, even how to build a sold machine.
but i digress....
If a PC is your life blood, (its not mine) then have 2, why not have 2.

Blue screen
no photos of it presented, by you.
is it the BSOD? with GEEK hex codes and memory dump data?
blue screens tells me , near nothing, heck my w10 shows blue screens and is doing MS updates, with clue at all its MS doing that.
cept the words, updating, MS is bad actor, here.
they pop up screens with NO LOGO or ID telling you who it is popping screens, my big gripe. for 25 years +
in the old days we got ( FNF error,or just a number )

why not post like this.
my India PC called. HP ProBook 6550b locks up
see at which point it locks up.
post a photo of hung screens or shutdown, (black) sure.
you went a way for 10m.
so did the PC go to hibernate mode?
go to CP control panel
click power
click advanced settings custom settings
mine now has , Larry Custome
and all modes say never turn off.
screen off never
pc off never
try to understand PC's have 3million transistors (1 failing is a problem)
and Windows has 3million bits to flip, right or wrong.
it's complex. it;s no toaster, that is for sure.
it could be, but isnt. (ask how, one can run linux, one can run Linus in ROM , one can run windows PE10 in ROM or on stick or CD.)
if you run Windows, 10 pE from CD, it will never ever fail again....
one can run windows in a virtual mode.
each time you boot , you got back to day 1, virgin windows.


then all these off.

if you see this then say BSOD.
blue screen of dreath
see that STOP, that is a CRASH, (the answer for this blue screen is different as is w10 blue screens , vast)
